prophet REV2 16 -- 8 out of 16 voices not working (SOLVED)

[vlazzarini]

Hi All,

I have a problem which appeared today switching the synth on after a month away, 8 out of the
16 voices are not working.

The first 8 eight notes do not sound, 9 - 16 are OK. It looks like I lost half of the voices.

This synth was originally an 8-voice, in which I installed the 16-voice expander. When I boot it, it shows
16 voice as expected. I installed this expansion over six months ago and it worked fine.

Is there any routine to try and diagnose this here? Any thing I should try?

Thanks

Fixed. I plugged the outputs in the output B.
