FRES: Filter Resonance Modulation

In this mode the Oscillator 2 modulates the Filter 1 Resonance.

Notice that the OSC Mix is fully set to OSC2, which means OSC2 is fully audible but also used to modulate the Resonance of Filter 1. This wiring (which is similar to the internal filter setup of the Roland TB-303) allows very high and well controllable resonant peaks.

As a matter of course, Filter Resonance Modulation has only effect, if a Filter is applied (see screen shot).


For best results, use Filter Resonance values between 50 and 100 and high OSC MOD values.


Controls the depth/amount of the Filter 1 Resonance Modulation (OSC2 > Filter 1 Resonance).
