Hi,
I just bought a RK-006 from Retrokits which I wanted to use to merge my 'Keith Mc Millen Softstep' and my 'Fishman Tripleplay wireless' together and send them to mulitple Axoloti's/midi units.
The Axoloti is receiving midi from both units in their respective channels via the RK-006. When connecting the USB from Fishman to the Axo USB input, the midi information is the same as with the RK-006. My patch however only reacts to the midi from the Fishman when it's connected to the Axoloti and not when it's connected to the RK-006.
Does anybody know why this is happening? Like I said, the midi information when monitored via the midi/monitor object is virtually the same.
Thanks!
Edit: unable to delete this post unfortunately so i'll just insert my findings here...
My patcher's midi device was still set to USB 
. So just here to let you know that the RK-006's midi merge function works wonders. Truly a great device.
