Nice! I can see how that would play nicely with the 2s and Deluge.
You can sample as you go with the Deluge, and with the right clock and trigger settings should be able to loop - I’m sure I’ve seen some YouTube demos on it somewhere!
I don’t have experience in these but I know the 4ms looping delay and the Strymon Magneto have looping modes.
Not sure about the Morphagene for strict looping but you could definitely do some interesting stuff with it… Qbit Nebulae v2 as well.
Perhaps others will chime in with their experience of all these modules and/or others that might fulfil the brief.
Happy New Year by the way @Spiderlab!
