Module 80-6L		VC Low-Pass Filter
	The 80-6 was available in four variants, the 80-6L Low-Pass was the most commonly used of these. Utilising the CEM 3320 VCF IC found in many synths of the era with a fairly standard 24db/octave response. The filter could be driven into self-oscillation for use as a sine wave  source if the tracking was calibrated to 1V/ octave correctly.
