[sdiy] New Insanium Layouts and DIY Board Information

[Lorin Edwin Parker]

Romeo,

	The headers near the PIC chip are connection points for wiring the  
pots, CVs and buttons. Essentially there are 10 ADC converters that  
turn the CVs (0-5V) into 16 bit numbers -- these are manipulated in  
the firmware to send instructions to the speech chip or other  
circuitry. So, frequency of the voice, modulation, etc can all be  
controlled with a CV between 0 and 5V. Simple mode changes and events  
are triggered by momentary switches which send high or low pulses  
(these could be gate triggers) and change the operation of the firmware.
