I’d really love to see a MIDI looper on the MOD platform, particularly with quantization. Bastl’s MIDILOOPER hardware certainly makes an argument for there being a use case.
I would also love a midi looper. I have a few already, but the only one I use is the Squarp Pyramid because it has a recording mode that constantly over-writes content, and therefor acts exactly as an old-school tape loop. This method is far better for live use than anything on an MPC, Maschine, or most other tools which are not ‘live friendly’.
