The Resonators section is set of three 12 dB/oct bandpass filters with a high amount of resonance (hence the clever name). The use of "vactrols" (aka, light-controlled resistors) in the original instrument gave these a pleasantly gooey, phaser-like tone. We've reproduced it super-accurately, if we say so ourselves.
There are three Resonator bands, all operating simultaneously. They can be set to a static settings or modulated via Mod Generator 2. These are similar to the famous Polymoog resonators, but unlike the Polymoog, they are easily modulatable, resulting in tons of awesome phaser-like tones.
Res Intensity- Simultaneously adjusts the overall depth of all three Resonators.
Resonator 1/2/3 frequency- Adjusts the frequency of each resonator from 10-20kHz. The front panel of the original PS-3300 says 10 kHz at the top end of the knob scale, but in our measurements, the resonator frequencies actually go up to 20 kHz, so we kept the original panel markings for authenticity but programmed the actual frequency response to be correct. Note that the popup tooltip displays the actual correct frequency when the knobs are turned.
Peak Freq Mod by MG2- Switching this to the down position enables modulation of all three resonator frequencies simultaneously via Mod Generator 2.
Resonators CV Jack
This jack is located at the bottom of the Mod Generator 2 section.
Ext Resonator Peak Freq Control- Allows modulation of all three resonator frequencies simultaneously. This is a bipolar input that accepts CV's from -5V to +5V. Negative CV's will decrease resonator frequencies; positive CV's will increase resonator frequencies.
