Re: [fluid-dev] fluidsynth tremolo (modulation)

[S. Christian Collins]

You can set up a modulator in the SoundFont to route a MIDI CC to the 
mod LFO volume, which will create a tremolo effect. However, as with the 
vibrato, this effect is aligned independently with the start of each 
note, which is not usually the effect you want for an organ, where a 
single tremolo effect should modulate all notes simultaneously.

Have you considered adding a tremolo effect plugin to the audio chain 
after FluidSynth?
