[sdiy] Modulated ADSR Generator

[Matthew Smith]

Hi Folks

Just working on a PCB design for a digitally controlled ADSR 
generator/LFO. (The LFO is just a wavetable setup - I've got spare FLASH 
  available in the microcontroller, so thought I might as well chuck 
some wave data in there.)

Current concept is an ATMega128 reading 8 parameter pots, doing some 
sums/lookups, sending values via SPI to a Microchip MCP4821 12-bit DAC, 
which then outputs a 0-5V control voltage.

I was wondering if there would be any value in sacrificing one of the 
pots in favour of sampling another control voltage, which would be used 
as a multiplier for the value already being fed to the DAC.

Cheers

M
