I always use a midi controller with the pyramid… and never had an issue.
you don’t mention which controller specifically… is this directly connected to the Pyramid via DIN, or are you connecting the controller to a computer, and then the computer to the pyramid?
(or using something like iConnect midi)
so i can only suggestion normal troubleshooting rules
- check cable and controller with another midi device
- use another controller to check to see if the pyramid is ok
- if your using any ‘intermediate router’ (midi router/computer) remove this from the setup.
if your having the sequencer start when your just playing notes, then that indicates that the midi is becoming corrupted on its ways to the pyramid (which would also explain the note-on/off getting dropped) … midi over din, is not a very robust protocol to hardware faults.
anyway, id test with another controller and cable, and if it still there, then its possibly a hardware fault, and id contact squarp support via email.
