Can somebody help with a MIDI setup please? I play a wind controller wireless via CME WIDI boxes to a Yamaha MU100R. Below is the basic setup and it works very good: But I need also SysEx from Logic. The MU100R has two MIDI ports, A+B. They seem to be completely independent, playing on port A and sending SysEx to port B does not change the sound. Can I tell the MU100R to accept this? Another possibility would be to send the SysEx via cable to the WIDI receiver that is attached to the MU100R. But so far I can tell the box doesn't work as a merger. Did anyone manage to get radio and cable input through a WIDI box without using USB? Here are the two setups which don't work for me: I tried with a third WIDI box to reach the same port as the wind controller but this is unstable. Do I need a merge box? Any other idea how I can keep the direct connection from the wind controller and send SysEx to the synth?
