i get some noise/interference on the individual outs. i must have done it wrong, or maybe should have used shielded wire. what results are you getting?

the snare mod, absolutely should be done, in my opinion, without soldering the capacitor directly to the points shown: i found it nigh-impossible to see, let alone get the soldering done directly to the capacitor. so i took a digital i/o internal cable for computer, and cut one end off, and soldered the wires to the points.
the capacitor gets inserted into the digi i/o connector, removable/swappable. definitely easier. you don't want to hang around too long with a soldering iron: get in there, get it done (keep it simple).

it does improve it, and the snare sounds better with a bit of short reverb.

a revised/punked firmware could add midi velocity reception - if used as a slave - and also change the PCMs. it's a shame it doesn't have more patterns. also reckon that a lot of people overlooked the fact that you can 'save' sound edits in each pattern, by switching off 'Global Stutter', and recording Speed and Depth per voice, and also Pitch/Speed on the PCMs. used as a slave sound module, this give, in a small way, 'kits'. ( a firmware could also be used to create pattern changes by remote, probably).
