Send a value of 64 to the unit on MIDI controller 10. I'm not sure if MIDI
pan is recognized by the 6r, but it's worth a try.

Is there a dedicated VCA for that channel If so, that might be something to
look at as well.

Subject: [oberheim] Matrix 6R - only Left/Mono out works...

My Matrix 6R has a strange problem - no matter which preset you select, with
both Stereo option ON and OFF, only Left/Mono channel works.
On headphones, on the other hand, you can hear both channels.

I am trying to find out whether this is an electronic problem or if there's
something wrong in the setting.

I tried the following to no avail so far:

1. Full Reset ("Calibration")

2. Replaced the 3 ICs at the final amplification stage, which are a 741,
4082 and 4053. When disconnecting the "Left/Ground/Ground/Right"
wire going from the main voice board to the headphones/out board, and
checking the output jack on the voice board with an audio probe, only left
channel plays, so I guess there is nothing to do with neither the output
jack board nor the headphones board.

I can't see any component the might have an influence on the right channel
alone, beside those 3 ICs which I've replaced...

Any suggestions

Thanks
