Physical guitar synth project

I am working on a "super sustainer guitar" but with a twist.

there is a lot of electronics, including 6 LM1875 amplifiers(chipamp.com) an AD/DA converter with 8 channels and ADAT, (fostex VC-8)modified) roland hexaphonic pickup and preamp (GK-2A) and an arduino mega programmed to output MIDI for the keys.
on the "box" side is a mini ITX PC with a SSD hard drive and a creamware pulsar board. and power supply for the onboard electronics.

it has keys to play the strings via very strong (for a sustainer) amplifiers and electromagnets, and the feedback signal to the strings is not just itself, but DSP modified, and other signals can be injected.

One could play normally as well and it would be much like "moog guitar" but with a lot more options for how the feedback works.

The keys allow it to be played with different attack signals than the normal plucking. below the keys normal stroke (like a keyboard) there is a long throw pressure sensitive range. it could be used to control something as simple as volume, or inject "pushes" depending on how fast you are moving it. then you can hopefully get a violin bowing effect a la "gizmo" (of course i wont know till i get it going)

anyways the project is at http://neutron-sound.blogspot.com

the DSP is done on an old creamware/soniccore pulsar on a mini ITX board. i have the SDK for it, and its the easiest way i could think of to do the guts of the system. (and i know it, as a long time owner of 36 DSP worth of 3 scope boards)

Thanks to brianGT for the chipamp.com lm1875 boards. he was super generous
