Tried this after reading about it this morning.
SEQ 1 - Mod Matrix > Set CV A to SEQ CHANGE
SEQ 2 - Mod Matrix > Set CV A to SEQ CHANGE
Sequence Playback Mode = SEQ
Main SEQ length = 1
Connect attenuator (UNI Mode) to CV A
Attenuator at 0 = SEQ 1
Attenuator at Around 10 O’Clock = SEQ 2
Works like a charm.
Initially I got hung up because the sequence would play 1 and switch to 2 then stay there… This was because I didn’t set the second sequence up in the Mod Matrix.
Also handy is to stay in SEQ mode so we can watch the pattern numbers change from 1 - 2 - 3 etc.
Just in case you want to know where you are and what’s happening.
