Messenger crashing on MIDI incoming + arp enabled

Hi,

Ever since I purchased Messenger, I found it hanging when it receives MIDI in messages (USB/DIN, doesn’t matter) and arpeggiator is enabled. It plays for couple of seconds and then it hangs, and by this I mean it no longer responds to keys, knobs, buttons. It plays last note continuously, leds are frozen in their last state. I have to turn it off and on again.

I’ve tried to tweak config settings, like disabling MIDI in/out in various combinations (3.4), restricting MIDI filter (3.5), but to no avail.

Firmware at newest version.

Anyone experienced this or is my unit broken?
