Discussion about the Korg PolySix synthesizer

Just noticed on my polysix that the ensemble effect doesnt
seem to work. Chorous and Phase work fine, but ensemble doesnt
seem to have an effect regardless of the position of the 
speed/intensity pot. Any tips as to what I should look for?

Thanks Ian.

I would start on KLM-367, CN03 (the one connecting to the effects board),
contact 4. This one enables the Ensemble effect. Is there any change when
switching to Ensemble?
This is also an area that could possibly be affected by a leaked battery.
