Very Strange Filter 2

I decided to put this into a case.  I get these boxes at Office Max for about $1.50.  They drill out pretty easily with the Dremel dry wall attachment.  Have all the hardware attached at this point but still need to add the wires.

The top of the box.

This shows the circuit board in the box.  No wires attached yet but all of the components are in place.  This is basically a three part filter.  Probably a bit silly of me to make this without breadboarding it first since I don't really know what it will sound like.

Created some sound in Csound based on this video I found on Youtube:

Planar Crystal Live Rig

Demo of the rig.

Planar Crystal Live Rig

My planar Crystal live rig consisting of Waldorf Pulse processed by Lexicon Vortex, Korg MS2000, MPC500 for sampling and sequencing, Thing 2 and Sequencer processed by Kaoss Pad.  Midi clock originates with MPC500 and controls arpeggiator speed on MS2k, Pulse, and KP3. I used Velcro to connect the Vortex to the pulse.
