Yeah that's close. Here's the way everything is hooked up:
MIDI A is working, MIDI C is working, MIDI B RX2 from the DAW is working but I can't get data out MIDI TX2 to record in the DAW. The only way I found to record is physically connecting a wire from the MIDI A DIN connector to the MIDI B Out DIN connector and that only records what comes out of the keyboard. The main goal is to be able to record everything that comes from the keyboard & control surface so I can automate all the CC messages.
At first I was thinking that since the synth puts out everything from Notes to CC and SysEx, that I could record / capture what's coming out of the synth into the DAW. I kind of need this because there are a number of Sysex codes for patch dumps, etc...that are triggered by buttons on the control surface.
Since MIDI C is receiving everything that comes from the synth already, (I already use SysEx messages to control the LEDs and LCD) I was trying to connect MIDI C to MIDI B to go to the DAW instead of connecting MIDI A and Control Surface separately to MIDI B. This would work but would not include any SysEx. Hope this makes sense.
