there is only one problem with
the pocket control. if you use a sequencer that won't be much of a hazzle, but manually changing between presets with the pin switch is a pain.
The only easy way, is to use your sequencer and make a program change, you're gonna have the sequencer signal routed through anyway...
Personally, i only use two different presets, 16*volume and a preset i've made for my supernova, so for me, it's just flicking a pin.
If you wanna use much more than 4-8 presets (64 controllers...) and you don't use a sequencer, you'll probably want something with more easy preset change (although, your synth can also send program messages...) but it's gonna cost ya...
To be more specific... the way you change between presets is with 8 little pins.. now they follow the binary logic, so as long as your presets are the first ones, it's really easy to switch..
preset 1 = the first pin.. preset 2 = the second.. preset 3 the 1 and 2nd... this get's more annoying as we enter the 2 digit numbers. but i seriously doubt you'll have any need of that...
If you use a sequencer, i say go for it... it's a really sturdy little sunnovabitch..
