Arduino Mega clone clone running our MIDI processing and spark trigger signal synthesizer software.
One ATX power supply
MIDI control via Arduino - Note on and off only at present, MIDI note stack, Voice allocation heat-load distribution algorithm
Custom polyphonic digital pin oscillator (because arduino's tone function is mono! boo!)
Variable duty cycle (to strike the arc on higher notes)
Proper antennae for the arcs!
As someone dropped the Arcophone, the case is much worse for wear. Christopher Hall and John Parker are designing a new one involving glass sounding boards also known as “Test Tubes”.
Current CorelDraw 16 files here:arcophoneboard.zip
Voice stacking + detune
Choreographed voice allocation modes, selectable by MIDI CC.
Frequency dependent duty cycle (to help charge the coils for the higher spark rates)
Velocity sensitivity by recruiting extra coils for notes
Mod wheel support
