Tom:

Using the Modulation control with the FluidR3_GM soundfont, causes a 
distorted sound for melodic instruments with vibrato. The creator of the 
FluidR3_GM soundfont, went with the idea that a sampled vibrato is 
better than what you get using the modulation control, so if you use 
modulation with it, you get a distorted sound.

I originally tried using the modulation wheel to control the relative 
loudness of the foreground and background voices,  as some other VST 
instruments do, but it also distorted the sound (because of the above), 
so I used the Balance control, which had no discernible side-effects.

Regardless, you can do whatever makes sense to you.  I am just 
indicating there are users taking advantage of the way things currently 
work, and changes may 'break' things that are working now.

Keep in mind, that you can do a lot with a MIDI router (such as 
qmidiroute), as I have already done.  Maybe some of these things are 
best done with a MIDI router, rather than in the synthesizer.

If you would like to look at my article explaining how to implement 
layered (composite) voices, using Qsynth, qmidiroute, and the 
KeyMusician Keyboard, you can read it at:
