Hi David,

["base reverb level" in soundfont + CC91] level does not make
mathematical sense to me.

Base reverb level is given in % value, CC91 is 0-127. What is the conversion?

(CC91/127 * base level) would seem to give us the 20% added to make
the maximum of 40% in your example...

So would it be (Soundfont Level % + [CC91/127*Soundfont Level %]) * FS
(global) reverb level?

Kind regards,
