Korg Poly800/EX800 Users

hi olaf,

thanks for those descriptions, they ought to make mods much easier :)
but one thing came to my mind looking at the sketch you drew: 
wouldn´t it be easier to solder the original trimpots out and then use 
*them* as resistors? would spare the hassle to measure them and buy 
resistors of the same capacity.... just a thought....(so don´t "just 
destroy them before you damage the PCB!" hehehe) anyway, i read 
somewhere that there are even more trimpots which could be redirected 
to external pots, here´s a list: 

VR1 - DCO Pitch adjust 
VR2 - VCF Frequency adjust 
VR3 - White Noise level adjust 
VR4 - DCO Fine tune adjust 
VR5 - VCF resonance adjust 

does it make sense to , err.. whats the word.... "externalise" the 
other three? 

i´m eagerly waiting to get my poly800 delivered (thinking of all this 
without even having one :) ), i´ll let you know what i did to it when 
it´s here.... hehehe modding all over.....
