About maximum polyphony and Voice Reserve
The MV-8800 can play 64 voices simultaneously, but there are certain limitations on polyphony due to the design of
the sound generator. Audio tracks are given priority so that they will be able to play 32 voices at any time. This means
that if audio tracks are playing 32 voices, the remaining 32 voices can be played by instruments.
● example 1

Instrument Part 2

In example 1, instruments are being requested to play a total of 16 voices, and actually are playing 16 voices. Since
the audio tracks are playing 32 voices, the entire MV-8800 is playing a total of 32 + 16 = 48 voices.

In example 2, the instruments by themselves are being requested to play a total of 72 voices, producing a shortage.
The number of voices specified by the voice reserve setting of each part are allocated and the remaining requests
are ignored so that a total of 64 voices are playing.

In example 3, the audio tracks are playing 32 voices, meaning that the instruments can play the remaining 32 voices.
However, there is a shortage because a total of 72 voices are being requested.
The number of voices specified by the voice reserve setting of each part are allocated, and the remaining requests
are ignored so that a total of 64 voices are playing.
