Thanks for this: I'm gonna have a look,
Just a little aside:
Some time ago,someone (not sure who) posted the notion of using dx modulation wheel as a substitute for breath control.
It suggested routing the modulation to the amplitude of the modulation index (which normally acts acts as 'lfo filter' equivalent) and setting the lfo to minimum thereby rendering increasing timbre from the modulation wheel.
I tried it,and it was a convenient substitution for bc: for those who don't have a bc.
Just thought I'd mention this as a reminder,as it might save a lot of arduous making of bc devices.
