VCAs are the heart of any system and the K6100 offers a small and flexible design that offers excellent performance in a small package. It looks great and sounds great, offering several different modes of operation. You can use it as two independent VCAs or combined for ganged / stereo operation. Each channel has an offset control that can be used to tailor the rponse based on your CV input source, or used as a manual volume control.
By using internal normalling connections, the input signals and CV signals are normalled to the second channel when only the first channel inputs are used. This allows you to use the K6100 as a dual VCA with the same source, or as a stereo VCA with the same control voltage signal. Or, for that extra level of dimension use the PAN IN control to adjust the relative balance between the two channels.
