I think i make my self clear in the subject but i will argument this:
1. The USB connection is working right now with Rig Manager based on the MIDI messages
2. Why we must use old and slow MIDI serial interface to the PC when right now Rig Manager uses USB to communicate with KPA with simple MIDI messages
3. Its a matter of simple MIDI driver Layer - one tiny midi driver and you will no need to have both Midi cables connected to you interface
Just think of this - the KPA communication is based on MIDI messages even with Rig Manager .
So this all is set up for KPA MIDI Device in PC.
Just give your +1(and like the Original Post) - so the KPA TEAM know how many likes there is from forum list) - i want to throw out this old school DIN5 cables.
