Dear Shareholder:


Continued U.S. economic growth and low inflation meant modest to strong returns
across Oppenheimer Multi-Sector Income Trust's three investment sectors--U.S.
government securities, high yield domestic corporate bonds and foreign fixed
income securities. The diversification among these sectors worked well, and the
Trust's six-month return was 3.48%, without deducting sales charges. Its
dividend return was 8.99% as of April 30, 1997.(1)

Of course, there were some strategic moves, in response to economic changes,
that helped the Trust's performance. Because the yield on U.S. government bonds
fell during the period, we reduced the duration of our U.S. Treasury holdings to
protect the Trust from excess interest-rate exposure. We've also increased the
Trust's holdings of foreign government bonds.



Investment Breakdown:
Oppenheimer Multi-Sector Income
Trust as of 4/30/97(4)


[GRAPH]



U.S. corporate bonds & notes: 31.0%
U.S. government obligations -- Agency: 20.2%
Foreign government obligations: 17.1%
U.S. government obligations -- Treasury: 13.1%
Structured notes: 6.8%
Foreign corporate bonds & notes: 6.6%
Short-term securities: 3.6%
Equity securities: 1.6%


Another factor that benefited the Trust during the period was that we were
heavily exposed to high yield corporate bonds in the telecommunications sector.
The break-up of monopolies, both in the United States and abroad, has been
beneficial for new companies in the high yield sector.(2)

In addition, our investments in dollar-denominated emerging market bonds,
particularly in Latin America, returned exceptional performance. Although yields
remain attractive, we are beginning to see high valuations and are looking to
diversify into other foreign debt instruments, such as those found in the
developing economies of Eastern Europe. Of course, any foreign investment,
especially emerging markets investment, entails greater expenses and risks, such
as adverse market changes due to currency fluctuations. But, by diversifying the
portfolio by country and industry, we aim to reduce those risks.

Finally, as the real estate market improved and strong economic growth helped to
lower office vacancy rates, we increased our exposure to a new source of
mortgage-backed bonds called commercial mortgage-backed securities. These bonds
are attractive because they provide higher yield for the same credit risk as a
comparable industrial corporate bond. In addition, the Trust's exposure to the
government sector was concentrated in mortgage-backed bonds, which maintained a
positive spread to Treasuries and provided respectable return.(3)

On the other hand, oversupply and regulatory changes hurt the performance of our
gaming sector holdings. Returns for these holdings were respectable but
disappointing when compared with some of the Trust's best performers. Also,
weaker growth in Asia and Europe dampened demand for our holdings in the metal/
mining and paper product industries. Although our investments in these three
industries underperformed our expectations, the Trust's low exposure minimized
the impact on performance.

Looking to the months ahead, we expect continued, modest economic growth, but
are cautious about too much inflation. Employment rates are reaching levels that
historically have begun applying upward pressure on wages. Although the Federal
Reserve didn't raise interest rates at its last meeting, rising wage
pressure--which is a key component of inflation--could tempt the Federal Reserve
to raise rates in the near future. Since we believe that the first rate hike by
the Fed will not be the last, we are taking steps to diversify the portfolio
away from interest-rate-sensitive investments. We remain confident that
opportunities exist both domestically and internationally to provide solid
performance in 1997.

Thank you for your confidence in OppenheimerFunds, The Right Way to Invest. We
look forward to helping you meet your financial goals in the future.

Sincerely,


/s/ BRIDGET A. MACASKILL

1. Total return is based on the change in net asset value per share from
10/31/96 to 4/30/97, without deducting any brokerage costs. Dividend return is
determined by annualizing the April 1997 dividend of $0.074 and dividing by the
closing market price on the New York Stock Exchange of $9.875 per share on
4/25/97 (payment date). Past performance does not guarantee future results.

2. Investors in high yield bonds are subject to greater risk that the issuer
will default in its principal or interest payments.

3. Mortgage-backed securities involve risks from early prepayment of underlying
mortgages that can affect the Fund's income and principal value.

4. Portfolio composition is subject to change. Chart is based on total
investments at market value rather than net assets.

 5. Represents securities sold under Rule 144A, which are exempt from
    registration under the Securities Act of 1933, as amended. These securities
    have been determined to be liquid under guidelines established by the Board
    of Trustees. These securities amount to $20,788,170 or 6.84% of the Trust's
    net assets, at April 30, 1997.
 
 6. Interest or dividend is paid in kind.
 
 7. Non-income producing security.
 
 8. Units may be comprised of several components, such as debt and equity and/or
    warrants to purchase equity at some point in the future. For units which
    represent debt securities, face amount disclosed represents total underlying
    principal.
 
 9. Identifies issues considered to be illiquid or restricted  --  See Note 8 of
    Notes to Financial Statements.
 
10. Denotes a step bond: a zero coupon bond that converts to a fixed or variable
    interest rate at a designated future date.
 
11. Represents the current interest rate for a variable rate security.
 
12. Non-income producing  --  issuer is in default of interest payment.
 
13. Indexed instrument for which the prinicipal amount and/or interest due at
    maturity is affected by the relative value of a foreign index.
 
14. When-issued security to be delivered and settled after April 30, 1997.
 
15. Interest-Only Strips represent the right to receive the monthly interest
    payments on an underlying pool of mortgage loans. These securities typically
    decline in price as interest rates decline. Most other fixed income
    securities increase in price when interest rates decline. The principal
    amount of the underlying pool represents the notional amount on which
    current interest is calculated. The price of these securities is typically
    more sensitive to changes in prepayment rates than traditional mortgage-
    backed securities (for example, GNMA pass-throughs). Interest rates
    disclosed represent current yields based upon the current cost basis and
    estimated timing and amount of future cash flows.
 
16. Principal-Only Strips represent the right to receive the monthly principal
    payments on an underlying pool of mortgage loans. The value of these
    securities generally increases as interest rates decline and prepayment
    rates rise. The price of these securities is typically more volatile than
    that of coupon-bearing bonds of the same maturity. Interest rates disclosed
    represent current yields based upon the current cost basis and estimated
    timing of future cash flows.

management investment company. The Trust's investment objective is to seek high
current income consistent with preservation of capital by investments among
seven sectors of the fixed income securities market. The Trust's investment
adviser is OppenheimerFunds, Inc. (the Manager). The following is a summary of
significant accounting policies consistently followed by the Trust.
 
Investment Valuation  --  Portfolio securities are valued at the close of the
New York Stock Exchange on the last day of each week on which day the New York
Stock Exchange is open. Listed and unlisted securities for which such
information is regularly reported are valued at the last sale price of the day
or, in the absence of sales, at values based on the closing bid or the last sale
price on the prior trading day. Long-term and short-term 'non-money market' debt
securities are valued by a portfolio pricing service approved by the Board of
Trustees. Such securities which cannot be valued by the approved portfolio
pricing service are valued using dealer-supplied valuations provided the Manager
is satisfied that the firm rendering the quotes is reliable and that the quotes
reflect current market value, or are valued under consistently applied
procedures established by the Board of Trustees to determine fair value in good
faith. Short-term 'money market type' debt securities having a remaining
maturity of 60 days or less are valued at cost (or last determined market value)
adjusted for amortization to maturity of any premium or discount. Forward
foreign currency contracts are valued based on the closing prices of the forward
currency contract rates in the London foreign exchange markets on a daily basis
as provided by a reliable bank or dealer. Options are valued based upon the last
sale price on the principal exchange on which the option is traded or, in the
absence of any transactions that day, the value is based upon the last sale
price on the prior trading date if it is within the spread between the closing
bid and asked prices. If the last sale price is outside the spread, the closing
bid is used.
 
Securities Purchased on a When-Issued Basis  -- Delivery and payment for
securities that have been purchased by the Trust on a forward commitment or
when-issued basis can take place a month or more after the transaction date.
During this period, such securities do not earn interest, are subject to market
fluctuation and may increase or decrease in value prior to their delivery. The
Trust maintains, in a segregated account with its custodian, assets with a
market value equal to the amount of its purchase commitments. The purchase of
securities on a when-issued or forward commitment basis may increase the
volatility of the Trust's net asset value to the extent the Trust makes such
purchases while remaining substantially fully invested. As of April 30, 1997,
the Trust had entered into outstanding when-issued or forward commitments of
$42,041,615.
 
In connection with its ability to purchase securities on a when-issued or
forward commitment basis, the Trust may enter into mortgage 'dollar-rolls' in
which the Trust sells securities for delivery in the current month and
simultaneously contracts with the same counterparty to repurchase similar (same
type, coupon and maturity) but not identical securities on a specified future
date. The Trust records each dollar-roll as a sale and a new purchase
transaction.

Oppenheimer Multi-Sector Income Trust
 
Security Credit Risk  --  The Trust invests in high yield securities, which may
be subject to a greater degree of credit risk, greater market fluctuations and
risk of loss of income and principal, and may be more sensitive to economic
conditions than lower-yielding, higher-rated fixed income securities. The Trust
may acquire securities in default, and is not obligated to dispose of securities
whose issuers subsequently default. At April 30, 1997, securities with an
aggregate market value of $34,000, representing 0.01% of the Trust's net assets,
were in default.
 
Foreign Currency Translation  --  The accounting records of the Trust are
maintained in U.S. dollars. Prices of securities denominated in foreign
currencies are translated into U.S. dollars at the closing rates of exchange.
Amounts related to the purchase and sale of securities and investment income are
translated at the rates of exchange prevailing on the respective dates of such
transactions.
 
The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Trust's Statement of Operations.
 
Repurchase Agreements  --  The Trust requires the custodian to take possession,
to have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Trust may be delayed or limited.
 
Federal Taxes  --  The Trust intends to continue to comply with provisions of
the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required.
 
Trustees' Fees and Expenses  --  The Trust has adopted a nonfunded retirement
plan for the Trust's independent trustees. Benefits are based on years of
service and fees paid to each trustee during the years of service. During the
six months ended April 30, 1997, a reduction of $2,505 was made for the Trust's
projected benefit obligations and payments of $5,021 were made to retired
trustees, resulting in an accumulated liability of $142,606 at April 30, 1997.
 
Distributions to Shareholders  --  The Trust intends to declare and pay
dividends from net investment income monthly. Distributions from net realized
gains on investments, if any, will be made at least once each year.
 
Classification of Distributions to Shareholders  -- Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
primarily because of paydown gains and losses and the recognition of certain
foreign currency gains (losses) as ordinary income (loss) for tax purposes. The
character of the distributions made during the year from net investment income
or net realized gains may differ from their ultimate characterization for
federal income tax purposes. Also, due to timing of dividend distributions, the
fiscal year in which amounts are distributed may differ from the year that
 
                                                                              27

the income or realized gain was recorded by the Trust.
 
Other  --  Investment transactions are accounted for on the date the investments
are purchased or sold (trade date) and dividend income is recorded on the
ex-dividend date. Discount on securities purchased is amortized over the life of
the respective securities, in accordance with federal income tax requirements.
Realized gains and losses on investments and unrealized appreciation and
depreciation are determined on an identified cost basis, which is the same basis
used for federal income tax purposes. Dividends in kind are recognized as income
on the ex-dividend date, at the current market value of the underlying security.
Interest on payment-in-kind debt instruments is accrued as income at the coupon
rate and a market adjustment is made periodically.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates.
 
2. SHARES OF BENEFICIAL INTEREST
 
The Trust has authorized an unlimited number of $.01 par value shares of
beneficial interest. There were no transactions in shares of beneficial interest
for the six months ended April 30, 1997 and the year ended October 31, 1996.
 
3. UNREALIZED GAINS AND LOSSES ON INVESTMENTS
 
At April 30, 1997 net unrealized depreciation on investments and options written
of $166,149 was composed of gross appreciation of $5,469,502, and gross
depreciation of $5,635,651.
 
4. MANAGEMENT AND ADMINISTRATIVE FEES AND OTHER TRANSACTIONS WITH AFFILIATES
 
Management fees paid to the Manager were in accordance with the investment
advisory agreement with the Trust which provides for an annual fee of 0.65% on
the Trust's average annual net assets.
 
Mitchell Hutchins Asset Management Inc. serves as the Trust's Administrator. The
Trust pays the Administrator an annual fee of 0.20% of the Trust's average
annual net assets.
 
The Manager acts as the accounting agent for the Trust at an annual fee of
$24,000, plus out-of-pocket costs and expenses reasonably incurred.
 
Shareholder Financial Services, Inc. (SFSI), a wholly owned subsidiary of the
Manager, is the transfer agent and registrar for the Trust. Fees paid to SFSI
are based on the number of accounts and the number of shareholder transactions,
plus out-of-pocket costs and expenses.
 
5. FORWARD CONTRACTS
 
A forward foreign currency exchange contract (forward contract) is a commitment
to purchase or sell a foreign currency at a future date, at a negotiated rate.
The Trust uses forward contracts to seek to manage foreign currency risks. They
may also be used to tactically shift portfolio currency risk. The Trust
 
28

NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)
Oppenheimer Multi-Sector Income Trust

generally enters into forward contracts as a hedge upon the purchase or sale of
a security denominated in a foreign currency. In addition, the Trust may enter
into such contracts as a hedge against changes in foreign currency exchange
rates on portfolio positions.
 
Forward contracts are valued based on the closing prices of the forward currency
contract rates in the London foreign exchange markets on a daily basis as
provided by a reliable bank or dealer. The Trust will realize a gain or loss
upon the closing or settlement of the forward transaction.
 
Securities held in segregated accounts to cover net exposure on outstanding
forward contracts are noted in the Statement of Investments where applicable.
Unrealized appreciation or depreciation on forward contracts is reported in the
Statement of Assets and Liabilities. Realized gains and losses are reported with
all other foreign currency gains and losses in the Trust's Statement of
Operations.
 
Risks include the potential inability of the counterparty to meet the terms of
the contract and unanticipated movements in the value of a foreign currency
relative to the U.S. dollar.
At April 30, 1997, the Trust had outstanding forward contracts to purchase and
sell currencies as follows:

6. FUTURES CONTRACTS
 
The Trust may buy and sell interest rate futures contracts in order to gain
exposure to or protect against changes in interest rates. The Trust may also buy
or write put or call options on these futures contracts.
 
The Trust generally sells futures contracts to hedge against increases in
interest rates and the resulting negative effect on the value of fixed rate
portfolio securities. The Trust may also purchase futures contracts to gain
exposure to changes in interest rates as it may be more efficient or cost
effective than actually buying fixed income securities.
 
Upon entering into a futures contract, the Trust is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are
 
                                                                              29

Oppenheimer Multi-Sector Income Trust

made or received by the Trust each day. The variation margin payments are equal
to the daily changes in the contract value and are recorded as unrealized gains
and losses. The Trust recognizes a realized gain or loss when the contract is
closed or expires.
 
Securities held in collateralized accounts to cover initial margin requirements
on open futures contracts are noted in the Statement of Investments. The
Statement of Assets and Liabilities reflects a receivable and/or payable for the
daily mark to market for variation margin.
 
Risks of entering into futures contracts (and related options) include the
possibility that there may be an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

At April 30, 1997, the Trust had outstanding futures contracts to purchase and
sell debt securities as follows:

7. OPTION ACTIVITY
 
The Trust may buy and sell put and call options, or write put and covered call
options on portfolio securities in order to produce incremental earnings or
protect against changes in the value of portfolio securities.
 
The Trust generally purchases put options or writes covered call options to
hedge against adverse movements in the value of portfolio holdings. When an
option is written, the Trust receives a premium and becomes obligated to sell or
purchase the underlying security at a fixed price, upon exercise of the option.
 
Options are valued daily based upon the last sale price on the principal
exchange on which the option is traded and unrealized appreciation or
depreciation is recorded. The Trust will realize a gain or loss upon the
expiration or closing of the option transaction. When an option is exercised,
the proceeds on sales for a written call option, the purchase cost for a written
put option, or the cost of the security for a purchased put or call option is
adjusted by the amount of premium received or paid.
 
Securities designated to cover outstanding call options are noted in the
Statement of Investments where applicable. Shares subject to call, expiration
date, exercise price, premium received and market value are detailed in a
footnote to the Statement of Investments. Options written are reported as a
liability in the Statement of Assets and Liabilities. Gains and losses are
reported in the Statement of Operations.
 
The risk in writing a call option is that the Trust gives up the opportunity for
profit if the market price of the security increases and the option
 
30
 
<PAGE>

<PAGE>
NOTES TO FINANCIAL STATEMENTS (Unaudited) (Continued)
Oppenheimer Multi-Sector Income Trust

is exercised. The risk in writing a put option is that the Trust may incur a
loss if the market price of the security decreases and the option is exercised.
The risk in buying an option is that the Trust pays a premium whether or not the
option is exercised. The Trust also has the additional risk of not being able to
enter into a closing transaction if a liquid secondary market does not exist.

Written option activity for the six months ended April 30, 1997 was as follows:

8. ILLIQUID AND RESTRICTED SECURITIES
 
At April 30, 1997, investments in securities included issues that are illiquid
or restricted. Restricted securities are often purchased in private placement
transactions, are not registered under the Securities Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as reflecting fair value. A security may be considered
illiquid if it lacks a readily available market or if its valuation has not
changed for a certain period of time. The Trust intends to invest no more than
10% of its net assets (determined at the time of purchase and reviewed from time
to time) in illiquid or restricted securities. Certain restricted securities,
eligible for resale to qualified institutional investors, are not subject to
that limit. The aggregate value of illiquid or restricted securities subject to
this limitation at April 30, 1997 was $18,018,798, which represents 5.93% of the
Trust's net assets. Information concerning restricted securities is as follows:

OPPENHEIMER MULTI-SECTOR INCOME TRUST
 
GENERAL INFORMATION CONCERNING THE TRUST
 
Oppenheimer Multi-Sector Income Trust (the Trust) is a closed-end diversified
management investment company with a primary investment objective of seeking
high current income. In seeking its objectives, the Trust may invest any
percentage of its assets in at least three of the following seven fixed-income
sectors: U.S. Government, Corporate, International, Asset-Backed, Municipal,
Convertible and Money Market. Current income, preservation of capital and,
secondarily, possible capital appreciation will be considerations in the
allocation of assets among such sectors. The Trust may invest in a number of
different kinds of 'derivative investments' and may also engage in certain
special investment techniques, including repurchase transactions, when-issued
and delayed delivery transactions and hedging. The investment adviser to the
Trust is OppenheimerFunds, Inc. (the Manager).
 
The Portfolio Managers of the Trust are Robert E. Patterson, Thomas P. Reedy,
David A. Rosenberg, Ashwin K. Vasan, Carol E. Wolf and Arthur J. Zimmer and who
also serve as Vice Presidents of the Trust and of the Manager, and are officers
of certain mutual funds managed by the Manager (Oppenheimer funds). Messrs.
Reedy, Rosenberg and Vasan have been the persons principally responsible for the
day-to-day management of the Trust's portfolio since August 1993, June 1994 and
August 1993, respectively. During the past five years, Mr. Reedy served as a
securities analyst for the Manager, and, prior to joining the Manager, Mr.
Rosenberg served as an officer and portfolio manager for Delaware Investment
Advisers and one of its mutual funds, Mr. Vasan served as a securities analyst
for Citibank, N.A. and Mr. Zimmer served as a Vice President of Hanifen Imhoff
Management Company.
 
Dividend Reinvestment and Cash Purchase Plan  --  Pursuant to the Trust's
Dividend Reinvestment and Cash Purchase Plan (the Plan), as to shares of the
Trust (Shares) not registered in nominee name, all dividends and capital gains
distributions (Distributions) declared by the Trust will be automatically
reinvested in additional full and fractional Shares unless a shareholder elects
to receive cash. If Shares are registered in nominee name, the shareholder
should consult the nominee if the shareholder desires to participate in the
Plan. Shareholders that participate in the Plan (Participants) may, at their
option, make additional cash investments in Shares, semiannually in amounts of
at least $100, through payment to Shareholder Financial Services, Inc., the
agent for the Plan (the Agent), accompanied by a service fee of $0.75.
 
Depending upon the circumstances hereinafter described, Plan Shares will be
acquired by the Agent for the Participant's account through receipt of newly
issued Shares or the purchase of outstanding Shares on the open market. If the
market price of Shares on the relevant date (normally the payment date) equals
or exceeds their net asset value, the Agent will ask the Trust for payment of
the Distribution in additional Shares at the greater of the Trust's net asset
value determined as of the date of purchase or 95% of the then-current market
price. If the market price is lower than net asset value, the Distribution will
be paid in cash, which the Agent will use to buy Shares on The New York Stock
Exchange (the NYSE), or otherwise on the open market to the extent available. If
the market price exceeds the net asset value before the Agent has completed its
purchases, the average purchase price per Share paid by the Agent may exceed the
net asset value, resulting in fewer Shares being

acquired than if the Distribution had been paid in Shares issued by the Trust.
 
Participants may elect to withdraw from the Plan at any time and thereby receive
cash in lieu of Shares by sending appropriate written instructions to the Agent.
Elections received by the Agent will be effective only if received more than ten
days prior to the record date for any Distribution; otherwise, such termination
will be effective shortly after the investment of such Distribution with respect
to any subsequent Distribution. Upon withdrawal from or termination of the Plan,
all Shares acquired under the Plan will remain in the Participant's account
unless otherwise requested. For full Shares, the Participant may either: (1)
receive without charge a share certificate for such Shares; or (2) request the
Agent (after receipt by the Agent of signature guaranteed instructions by all
registered owners) to sell the Shares acquired under the Plan and remit the
proceeds less any brokerage commissions and a $2.50 service fee. Fractional
Shares may either remain in the Participant's account or be reduced to cash by
the Agent at the current market price with the proceeds remitted to the
Participant.
 
Shareholders who have previously withdrawn from the Plan may rejoin at any time
by sending written instructions signed by all registered owners to the Agent.
 
There is no direct charge for participation in the Plan; all fees of the Agent
are paid by the Trust. There are no brokerage charges for Shares issued directly
by the Trust. However, each Participant will pay a pro rata share of brokerage
commissions incurred with respect to open market purchases of Shares to be
issued under the Plan. Participants will receive tax information annually for
their personal records and to assist in federal income tax return preparation.
The automatic reinvestment of Distributions does not relieve Participants of any
income tax that may be payable on Distributions.
 
The Plan may be terminated or amended at any time upon 30 days' prior written
notice to Participants which, with respect to a Plan termination, must precede
the record date of any Distribution by the Trust. Additional information
concerning the Plan may be obtained by shareholders holding Shares registered
directly in their names by writing the Agent, Shareholder Financial Services,
Inc., P.O. Box 173673, Denver, CO 80217-3673 or by calling 1-800-647-7374.
Shareholders holding Shares in nominee name should contact their brokerage firm
or other nominee for more information.
 
Shareholder Information  --  The Shares are traded on the NYSE. Daily market
prices for the Trust's shares are published in the New York Stock Exchange
Composite Transaction section of newspapers under the designation 'OppenMlti.'
The Trust's NYSE trading symbol is OMS. Weekly net asset value (NAV) and market
