Strange issues with my new Rev2

[Kai-vD]

I'm new to synths and just purchased a Rev2. I did the Firmware update and calibrations.

When my external step sequencer the Arturia Beatstep is running, sending on MIDI-Channel 1 as a master, I hear the steps in the Rev2 but not always: sometimes a step is missing or seams delayed.
And then suddenly the poly sequencer starts automaticly and also stops after a while, without me doing anything, and sometime there is suddenly a permanent high whistleling tone, that only stops when I change the editing layer. Even when I load a basic patch this happens - whats going on?

Seams as if it had something to do, that the Arturia got the USB-Power from a Socket of my PC. Now that I switched the power out of the PC and into a normal power plug the issue seams gone...
The P12, that I had before didn't react with issues... I'll keep an eye on this...

Hi Kai-vD, just check your MIDI slave configuration. I believe the Beatstep is sending MIDI start/stop signals when you press the play/stop button. The "normal"  MIDI slave clock (in globals) setting on the Rev2 starts the poly-sequencer when it receives a MIDI start datagram. Switch it to the next slave setting (Slave no S/S) to disable this function.
