INTernal source
A SWEEP OUT signal is available on the VCF IN BNC (GX 305/310)
or VCG IN (GX 320).
It is a proportional signal with a generated frequency, amplitude from 0 to 2V.
EXTernal source
The generated output frequency is proportional (according to a linear or
logarithmic rule) to the voltage on VCF IN (GX 305/310) or VCG IN (GX 320).
The command signal is sampled on 8 bits using a frequency of 60 kHz.
