QUESTION: Can Filter Spacing or Resonance be modulated on the Minimoog Voyager XL?
A. Because the Voyager XL (and Voyager) hardware is designed the way it is, there is a control input for the Filter Cutoff Frequency, but not the Filter Spacing or Resonance. We had to draw a line as to how many dedicated CV inputs we could include. In the end we chose those inputs that we felt had the most utility and we had to remove a few that were more esoteric.
However, we cleverly designed in a few hooks that provide the Voyager flexibility in routing external CVs to controls that don’t have a dedicated CV input. This can allow external control Voltages to control things like Filter Spacing etc.
The MOD1 and MOD2 inputs accept 0 to +5V control inputs. The MOD1 input is the controller for the Pedal/On Mod Buss, normalled to +5V. The MOD2 input is selectable as a Mod Source for both Mod Busses, normalled to +5V.
Note that Filter Spacing can be selected as a Programmable Modulation Destination in either Mod Bus. Thus you could route the MOD2 input to control Filter Spacing through the Mod Busses.
Also, either MOD1 or MOD 2 inputs may be routed using the Voyager’s POT MAPPING feature to control any of the front panel knobs, including Filter Spacing or resonance.
