Each VCA section's characteristic and thus the response to CVs can be set either linear or exponential.
Linear is better for processing the amplitude of control voltages while exponential is better for audio signals.
The initial level can be set manually with the gain potentiometer i.e. you can open the VCA manually. The CV input has an attenautor for adjusting the modulation intensity.
per VCA: input, output, CV input
