another thing that you may want sooner rather than later is a way to control the modular with your foot - especially if you are playing guitar into it... addac and doepfer make one and there is a diy one available from thonk by a company called 7 dials

look at them carefully though, as you may find that you already have all you need other than the module to get that to work - usually a passive volume pedal - but iirc some of them can also take a switch

Thanks for this info. I actually do have a passive volume pedal.
