Routing Causing MRCC to Freeze

[Eamoex]

Thanks to Jesse's help, we've narrowed down the problem to improper USB host port functionality when using Arturia's KeyStep37. Which side is problematic, the MRCC or KeyStep37, is impossible for us to tell. This connection hangs the MRCC pretty fast, and it recovers by power cycling the KeyStep37. It might be a MIDI loop of some kind, but we configured a channel modifier to ensure the was no backtalk (the KeyStep37 uses an unique channel, IN and OUT), and still the problem is there.

Plugging the KeyStep37 through DIN ports exclusively completely solves the problem, though.

Thanks for great support.
