Hi Alan,
For me it is easier to compare and tweak two tones, say you like patch x but you would like it with a little extra something then you can copy and paste into a new tone and tweak.
hopefully then you can name the patches.
if the computer interface would be just an exact replication of the knobs on the screen and you still have to do a lot on the pedal such as bank changes, then I am not so interested.
I guess in an ideal world i would like something such as the line 6 gearbox / workbench. they work really well as a computer interface to a musical device.
Cheers
BMF
