I have a Intellijel Tetrapad that I just put up for sale.
While it’s possibly not as cool looking as the ones on your list, it’s a pretty versatile module. The feel and response of the touch pads are really nice, it’s super fun to slide your fingers and get such a detailed non-stepped response on it. The finger tapping and keyboard modes are super useful.
I actually found myself using the stored CV value mode a lot as a sort of patch recall thing. You would select one “preset” location, dial in settings with the encoders within your patch, then then hit another location and dial in completely different settings. Then if you set a really slow “fade/slew/transition/whatever” time it would slowly morph between them as you hit each pad. Fun way to perform evolving drone stuff. Really smart.
I’m selling it because my case is super small (just like I like it) and ever since I got my CV.OCD’s I have a bunch of external MIDI controllers that serve a similar function as the Tetrapad, so it makes more sense to reclaim the hp in my case.
