Interestingly after my last post, I experimented with certain settings and found that at the start of any session using the Oxygen 49, whatever the settings in the Controller or RB, I always obtained the default Piano Patch 1 to start with.

Previously, I followed my routine as above to get started. Now, I can open the RB Classic Tracks Window, select the Program number for a track, click to open The Patch Window, select the patch and select "OK" to close the Window to set up the connection. This sometimes works for other tracks without the need for an additional Set Up. I am using a Ketron SD2 as the synth and this seems to wake it up with no need to adjust the Midi Controller.

I have used the "Wake Up" method for sleepy synths in the past.
