There is a snapshot functionality within Surface Builder – you can set 12 knob states up for instant recall. But every NTS-1 will be unique if it has user oscillator/mod/delay/reverbs installed. That makes sharing patches more difficult. But for your own use, snapshots would seem to be the way to go. I’ll play with it and if it makes sense to make snapshot recall part of the interface, I might release a 1.1 version.
