I gave this a shot with the SQ-1, and it does look problematic. The issue is the SQ-1 enumerates as 2 separate MIDI devices (which I first noticed on the iMac), one for input, and one for output. By default the Organelle selects the first one on the list (in this case the input), but even worse the output device doesn’t show up at all in Pd… so SQ-1 as Organelle to CV doesn’t seem promising atm…
