This is exactly what I've been planing on doing: two single pots at the wiper 
of each axis, one as a divider and one as an offset. But also having a switch 
for each axis to allow the input of signals instead of +V and -V on each side 
to allow it to be used for crossfading.

I'd change range to scale, and trim to offset.

I'll have to think about this.

Again, this is what I was thinking of since some examples off hand are gate 
an EG, clocking a S/H (with the input of the S/H from one axis of the 
joystick), and using it with a flip flop to switch between inputs with the 
MOTM 700.
