Editing a sampled soundMain FeaturesContents Parts of the MV-8000 and what they do Sampling
This specifies the number of samples that this part will always be able to play
simultaneously. If you attempt to play more than 32 simultaneous notes (sample
voices), previously-sounding notes will be turned off according to certain rules so that
the newly-requested notes can be sounded. However, the VoRsv parameter lets you
reserve a certain number of notes that will be guaranteed to be available to each part.
You can't set the Voice Reserve
parameter in a way that would
cause the total for all parts to
exceed 32.
About maximum polyphony and Voice Reserve
The MV-8000 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
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-8000 is playing a total of 32 + 16 = 48
voices.
❍example 2
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.
❍example 3
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.
