Korg Poly800/EX800 Users

I completed another smooth mod 4 the poly800. I used a normally-closed 1/8" 
jack to cut the noise source and allow you to send an external audio source 
through the noise VCA->VCF. Also, the onboard chorus can then effect the 
ext. audio signal..nice

I tapped the audio input at the "+ input" of capacitor C24. Basically, I 
desolderer the "+" lead of C24 from the circuit board. I ran a wire from the 
now-desoldered "+" lead to the "tip" solder lug of a 1/8" phono plug. The hole 
that the "+" lead of C24 was removed from, i soldered a second wire from this 
to the "Normaly-closed" lug of the phono jack. Finally, a third wire from the 
"ground" lug of the phono jack to a suitable "ground" point inside the poly800. 
The input is suitable for line-level audio signals. The poly800 has one hell of a 
nice sounding VCF filter. In the absence of a jack being plugged into the 
phono jack, the noise source is processed through the poly800 in normal 
fashion.

Enjoy...use caution & mod at ya own risk buckeroo!
