I’m having the same trouble. Tried everything I can think of but still can’t get the midi thru to work. I’m trying to send midi from Ableton, through the keys or rytm into my downstream midi synths (Juno 106 roland and cs1x Yamaha).
I have ableton (triggered by push as the key player), sending midi out to elektron keys or elektron rytm, then midi thru from either of these into my Roland Juno 106, or Yamaha CS1x.
I can get the keys to receive and play the notes via USB midi in (when i say accept note data, so i know the signal is there and the cable is working), but can’t get the midi message past the keys via thru into the Juno or Yamaha. I’ve tried sending out from ableton on a channel that is not used by any of the keys or rytm tracks (e.g. 14) and having the thru going to midi in of the external synths, but still nothing. I’ve tested the midi signal from the keys to the juno / yamaha by choosing the midi-ext button and the key presses send data, so again, this confirms the functionality of the cables and the ability to receive signal…
Anyone experienced and/or solved a similar problem?
