[LAD] Software sound

Hi Nick,
Sounds interesting, but also rather vague. What was the base waveform, the cutoff freq, the quality factor, the kind of internal filter distorsion? If the differences between Moog and Chamberlin are 
subtle, then Moog isn't worth its extra CPU cycles.

'Warmth' depends on the lower harmonics. If you are aiming for warmth then start with a base signal with more lower harmonics, e.g. a square wave i.s.o. a pulse. Also equalizing and a suitable 
amplifier are important. And the ultimate way to get warmth is to add a small amount of 1/2 or 2/3 harmonics. In software this is easy, for real instruments it's impossible!
