OK, I just compiled the latest CVS version and tested. Taking your
above example, everything works correctly when connecting and starting
processing. There is one unexpected result for me: after the first
MIDI-CC is received, the copp jumps to the lower-bound value given in
the ctrl.

Continuing with your above example, upon connecting and starting, the
-efl starts at 1500 (works as expected), but as soon as I send a
MIDI-CC signal to increase the value, it begins increasing from 400
rather than from 1500 (not expected). Likewise, an incremental
decrease jumps straight from 1500 to 400 (also not expected).

Perhaps a more revealing example could be [...] -epp:50
-km:1,0,100,1,1 [...]. I was hoping we could not only start with a
centered pan (currently working, a great improvement!), but that we
could get a MIDI controller to function like a typical mixer pan. With
the above example and latest CVS, we jump from center (copp) directly
to hard left (ctrl lower bound) before regaining "incremental
control".

I hope that all makes sense.

Thanks again,
adam
