I had this problem for a few weeks. First I blamed the hardware synth I triggered with the Keystep, a few weeks later in Ableton I thought my new audio interface was responsible for glitch sounds once in a while... As I'm still in the middle of connecting my new set up I wasn't sure about the glitches but I didn't blame the Keystep until tonight.
While recording a simple beat the sound in Ableton froze for 1 second. First I thought it was a latency issue but after checking the recording I saw the pattern actually received extremely fast and random midi notes from a key I pressed before. The same "freezing" I had while triggering my analogue synthesizer via midi (CV works fine btw).
Is this a known bug or is my unit broken? Thanks in advance!
