[T DSS-1 memory arrangement and data storage
■ DSS-1 internal memory is divided up into three main
sections; These are wave memory, program
memory, and the program output buffer. This ar
rangement is shown in the diagram here.

■ Wave memory is used for three purposes. First, it is
used to hold and edit sounds. Second it is used to
make single multisounds. Third, and finally, it is used
to store a number of multisounds.
Wave memory has a capacity of 261,000 “data
words” or samples. This is about enough for a
16 seconds digital recording at a 16kHz sampling fre
quency (since 16,000 samples per second times 16
seconds equals 256,000), or 11 seconds at 24kHz, or
8 seconds at 24kHz, or 8 seconds at 32kHz, or 5*5
seconds at 48kHz.
This same wave memory can be used to hold up to
16 multisounds as long as the total data does not ex*
ceed this capacity* (Therefore, OSC-1 and OSC-2
can each use any one of these 16 multisounds.)
■ The point is that wave memory can not be used for
more than one of these purposes at a time. (Nor can it
usually be used to process different data at the same
time even if the purpose is the same.) For example, if
you try to make a new multisound when wave
memory is being used to store a number of multi-
sounds then you will destroy all of your stored mufti-
sounds. Similarly, if you have completed a multi-
sound in wave memory and then try to make another
multisound or edit a sound, you will destroy the com
pleted multisound. Use the disk for storage of
memory contents when you want to use the memory
for another purpose or to process different data.
• Uses of Wave Memory
i) For temporarily storing and editing a sound.
ii) For making a multisound.
iii) For storing a number of multisounds.
• Wave memory capacity is about 261,000 words*
• Wave memory maximum multisound storage capaci
ty is 16.
• After completing one multisound, if you try to use
wave memory to complete another multisound, the
first multisound will be destroyed.
