Stuck notes from midi sequencing

having an absolute nightmare with stuck notes from several sources(not at the same time) - pro tools/squarp hapax/i pad/ableton to the point where the super 6 is pretty much unusable.

anyone else aware of this?

have had so many issues with this synth since i got it. i thought this far down the road a lot of the creases would be ironed out. sounds incredible but it’s doing my nut in 80% of the time
