Hi Tim (and other list members),

Trying to stay within the power requirements of the single A-100MNT
Power Supply, which 4 Doepfer modules would you select in putting
together a nice little pure tonal/drone synth

Would it be possible to create the effect of a two oscillator beating
drone sound by using a module such as the A-115 Audio Divider or A-116
Waveform Processor

Man, I wish I had access to these modules...I could figure all this
out in 30 minutes. *sigh*

Best, Jamie.
