i used to have a row of switches along the bottom of mine, but i took
them out to mount the pots. i bet there's enough room for a switch
next to each pot. or you can rip out the cartridge slot like i did
before i found out the rom switching wouldn't work. right now i've
got the 9 knobs on the bottom, 3 vca input mini-jacks on the back
next to the ride output, and 4 decay knobs and 3 vca input switches
on the right side. i still have the cartridge area and the whole left
side to fill up, probably with bends and switches for future trigger
outs. oh and maybe pan pots. by the way, if there are any jacks on
the back that you don't use, you can cut the traces around them and
wire other things to them; i use the tape in and out because my
patterns don't save anymore but there's also the start/stop jack
which i've never needed. i'm going to need jacks for triggers
somewhere.
