SQ-1 doens’t save sequences, right?
There are sequencers and synths with memory if you don’t wanna spend much - Beatstep (Pro) + synth, or Korg Monologue, Novation Circuit or the new Arturia Microfreak for example. Even Korg Volcas have 16 memory locations.
Btw, sure you wanna witch patterns? Sounds dangerous…possibly great outcome, though^^
