polyphony varies amplitude
I am working on a polyphonic synthesizer and I am wondering if there is
a generally accepted way (method and degree) for automatically
lessening the output volume as the number of sounding voices increases
in order to avoid distortion.
Thank you, community, for your help; and thank you, Cycling ’74, for
the new web site and forms.
If I understand what you’re proposing, the voice number output by poly
does not necessarily = the number of voices. However, I have worked up
a patch that does indeed divide the the amplitude by the number of
voices (derived from the busymap thru iter which may be a round about
way for all I know)).
This curve 1 1/2 1/3 1/4 . . . sounds too drastic to me though. Before
I get into experimenting with different curves, I thought that I would
see if there was a standard that I could Simply adhere too.
I will try out normalize~, it hadn’t occurred to me.
Try sqrt(1), sqrt(1/2), sqrt(1/3)…

that’s a better andwer, but tim place’s [tap.elixir~] is very nice.
i have worked up a method that iterates and counts a busymap from
poly~. i am happy with the sqrt(1) sqrt(1/2) curve but since it’s not
at audio rate, it is not near as smooth as tap.elixir~. i haven’t been
able to think of another method of determining the # of voices sounding
in a polly~. i still haven’t tried normalize~, which may be my best
