I just got the new, crowd-funded version of the HC-TT yesterday. From first blush, a really cool device. I got the Stereo Field first, which I’ve sometimes used as a mixer for a grainier, low-fi effect. Those drum-pad thingies are the Octagong from Morfbeats, plus one of their Gamelan tones. The sound of those things is amazing. Seek out a video on the topic by Hainbach. I strategically placed four pieces of high density foam tape on the underside of each, enough to suspend them from the table surface which is sufficient to achieve a clear, ringing sound. I often record them into the Cocoquantus loopers via the XLR mic input and then deconstruct the bell-like sounds accordingly.
