Erasing midi events in step program works similar to erasing events in sample banks. But in live (pattern) mode, the midi events can only be erased outside multimode.
So I run the sequence in pattern mode. Activate recording, activate multimode pitch. Then I press and hold erase while pressing a pad that corresponds to the pitch of the recorded midi event. The events are not erased. This issue includes the ‘basepad’.
This might be related to:
But @rudyrhythmz has not supplied more info yet.
I recorded the midi events using the S2400 pads, so it might be unrelated though.
