I am the author of eplayOrgan which uses fluid synth to produce its sound.
I am trying to implement tremolo (= midi modulation) and am using
fluid_synth_cc(synth, midichannel, 1, 100) to turn it on.
As far as I can tell this does not work, I get FLUID_OK returned but there is no modulation on the sound.
I am currently using fluidsynth version 1.1.8 on Windows.
Is this feature implemented for modulation?
If not how can I use fluidsynth to produce modulated notes in my organ. I know it can do it because qsynth provides modulation when driven by my midi keyboard and the "Modulation" wheel is advanced.
I have searched all the available documentation and your forum found nothing helpful.
