To get this now you need to select Unison, and start bristol with the parameters
below. In the current release the code does a default invocation of the emulator
parameters which limit the voices to something like the original, eg, the mini gets
a single voice (that rolls all the time irrespective of what notes you give it) and
the Prophet-5 gets, er, five. It should introduce a little 'detune' to make the sound
move a bit more but. It is pretty arbitrary detune, it doesn't change with time, only
with key events and I was considering making it a bit more like temperature drift
over time which at the moment it isn't.
startBristol -prophet -voices 32
When you select the emulator I configure some defaults that get reported in the
output. The assigned voices should all get a different amount of detune as that is
how it is coded.
Andrew reported that this 32 voice unison, dual oscillator synth, currently uses
about 65% CPU on a 2.X GHz processor, or about 2% per voice although you
will need a late 0.50 or 0.60 to do that. Previous releases (0.40) required a bit
more CPU, about 10% per voice, which means this same attempt would make
Jack very, very unhappy - a realtime thread asking for 320% CPU. This was one
of the main reasons bristol was not really considered to be RT safe (there were
other reasons too but they should also have been removed in the later releases).
The CPU footprint can be reduced further by selecting -lwf, or light weight
filters, they should cut a half off again for a small change in quality. If you
want to use more CPU you can too, documented in the ChangeLog.
