Display Morehere's the changelog from 12.1.2 to the 13 beta:
Audioadded: Fixed FX for PROFILER MK 2 models and Player (all Levels)
added: eight USB Audio channels (four in plus four out) at PROFILER MK 2 models
added: a few additional permanent presets at various Wah effects and Vintage Chorus (all PROFILER models)
added: Looper recording time doubled to 120 seconds, if Looper Location Input is select (PROFILER MK 2 and Player Level III)
fixed: Looper Stop button at First Recording
Are the 8 USB audio channels for the player as well? I'm a bit confused since the player is part of the mk 2 lineup according to what I've read everywhere, but the first point in the changelog goes through the effort to mention the player separately which makes it seem like it is seen as a different entity in these notes.
