We have a Roland A-80 connected via a midi cable to a Proteus/1.  The 
Proteus Mono out feeds into a line balance transformer and into 
the balanced input on a Yamaha 24 channel mixer board.  
We have the following problems:
1) The 6 lowest base notes drive the mixer board crazey.  It looks
like spikes are being inserted into the signal at about 2 hertz.
2) Every so often during performances, the synth surges - that is
if gets really loud and then returns to normal volume.  I have
seen it do this when noone was even touching the volume pedle.

Any suggestions?
