I have a problem with tempo syncing Ableton with the KeyStep 37.
When I play Ableton, my KeyStep starts playing and syncing and showing the same tempo as Ableton on its display. But then the sound start glitching / crackling, and after a glitch I see the tempo on the KeyStep display go up and down, and then resyncing to the Ableton tempo. This while on Ableton I do nothing. It even happens when I have an empty Ableton set, while listening to Spotify (the Spotify sound glitches and same behaviour on the KeyStep).
I have the jumpers on USB. USB Cable connected to my Mac, directly in the KeyStep USB slot (via a usb dock, but I feel the same happens when taking the dock out).
I use a Fireface UC on a Mac (Catalina)
I did the latest firmware 1.0.4.
Strangely, I believe this does not happen when I use my onboard sound card on the Mac.
Also, when in Midi control center I store to working memory (with Ableton not running), I hear Spotify glitching.
