I found a piece of wood on the beach, round and smooth, nice to hold.
I've routed with CNC to house a proto circuit for a polyphonic touch synthesizer.
The spiral pads on the top present individualy tuned oscilators that sing when pressed and can be bent with the lower pads.
I've been playing with circuit ideas for this for a year very undecidedly. Although I wasnt satisfied with this result the open circuit on top led to realisation that I can route the signals directly to the amplifier through my fingers instead of having dicrete vcas for each oscilator . Therefore
-enabling a more sesitive touch effect
-removing unwanted oscilator noise bleeding though the vcas
-reducing the part count by 70% or more
