Yamaha DX9 Operating Manual page 2

CONGRATULATIONS
Thank you for choosing the Yamaha DX9 Digital Programmable Algorithm Sy nthesizer.
The DX9 employs unique and sophisticated FM digital tone generation technology
combined with microcomputer control to permit creation of voices that are more "live"
than voices available with any other system available.
We urge you to read this owner's manual thoroughly to ensure proper operation and
maximum performance of the instrument.
Features ---------------------------------.
• The DX9 has a 20-voice internal memory, while
external cassette tape can be used to store and
load other voices. The DX9 is provided with a
voice tape containing 120 pre-programmed voices.
• Extensive microcomputer programming control
makes it possible to edit existing voices to change
their character, or produce entirely new voices.
New voices can also be created "from scratch."
• Edited or new voices can be stored either in the
instrument's internal memory, or on an external
cassette tape, so sounds you create can be saved
for future use.
