[timidity-talk] Convert midi -> mp3 while adusting for channel volume

[Martin G. <ge...@cr...>]

Hello,

I have a midi file with multiple channels (say bass, tenor, alto, 
soprano). How to produce multiple mp3s with different volume 
distributions (say b=+0, t=+0, a=+0, s=+0; b=+0, t=-12dB, a=-12dB, 
s=-12dB; b=-12dB, t=+0, a=-12dB, s=-12dB; etc)? Thanks in advance for 
any help!

Martin
