Re: [sc-users] make your digital oscillators sound like a moog!

["Sean Costello" <seancostello2003@xxxxxxxxxxx>]

The problem is that most people who have tried to figure out how to emulate
the behavior of a Moog modular synth haven't ever put their hands on a real
one. Most people who build their own synths use a +- 15 volt power supply,
with nice modern regulation. The Moog modular (apparently) had a very noisy
power supply, working at lower voltages, so more noise would come through
the power supply. In the Moogs and other synths, the reference voltage for
the sawtooth oscillator reset comes from the power supply without much
regulation, so noise in this reference voltage would cause the oscillator to
reset at slightly different levels each time. This seems like it would
slightly affect amplitude as well as frequency, but I'm not the guy with the
expensive modular synth and the scope, so I have no way of verifying this.
