I just made first proof of concept test with above configuration.
I designed layouts in Ipad Air 2 with Midi Designer for the BeatBuddy and Chase Bliss Wombtone mk ii.
I connected over bluetooth to Puc+ which was connected to Beatbuddy.
Beatbuddy Midi out was in merge mode.
Beatbuddy was connected to Empress Audio Midi box which was connected to Wombtone.
Empress Audio Midi through was connected to Infinity looper.
Everything worked fine.
I coud send commands to Beatbuddy and Wombtone.
Wombtone received midi clock from the Beatbuddy.
Sync between Beatbuddy and Infinity worked fine.
This is really great
