KeyStep Arp not in rhythm

Hello everyone,

I’m using the KeyStep as a MIDI slave, and I want to use the arp according to the clock sent by a computer (using FL Studio). Unfortunately, as the song progresses the keystep arp shift and is no longer in rhythm with the song (even if it was the case before).

Anyone had the same problem? I tried the same thing with a MiniFreak, and I had no problem, which make me think the problem comes from my Keystep…
