Polysix Unision detune mod successful

2007-10-26 by gil_we

I just wanted to note that I've modded my P6 to have a trimmer 
controlling the unison detune effect. 

I must say 
(and warn) that THERE'S NO NEED for a POT to be placed on the front 
panel. 

The affect of the control on the detune is very aggressive, so I 
found no point in having that control available for the user. Just 
use a trimpot and set to the deisred position.

What I did:

Took R116 (on the main voice board) and replaced with a 4.7K resistor.
Then soldered a 5K trimpot to R116 legs, using the wiper and one of 
the trimpot ends. Set the position to the desired detune effect in 
Unison mode while having the board still outside the synth wood case 
and just then securing it into the bottom plate (the trimpot will not 
be accessible once the board is secured in)


Good luck ;)
