Hi Guys,

I’m new here.
I was searching for mods of the Micro Synth.
The most interesting mod was the extention with the EXP pedal …

So first of all I modded my FV300 Boss/Roland volume pedal to an expression pedal.
Secondly I drilled a hole in the chassis of the Synth, added a switchable stereo jack connector.

An expression pedal is nothing more than a potentiometer, similar to the sliding pot of the stop freq.
So, cut 2 tracks connected with the slide “stop freq” pot. and connect the wires to the jack connector.
In that way, when no jack plug is inserted the switchable connector makes the connection again of the cut tracks. When inserting the jack, the “stop freq” pot will be disconnected and the tracks will be connected with the EXP pedal.

I will try to add some pictures on the forum.

The mod is really great and quite easy! Took me 20 minutes, a stereo jack connector and 5 wires.

Ciao.
