Frostwave Funk A Duck Resonant Envelope Filter

Description
The Frostwave Funk A Duck is an incredibly versatile and dynamic resonant envelope filter. The envelope is volume controlled so when the signal you put through such reaches a certain volume the envelope will flip open and send the signal via the filter. You can switch between high pass and low pass cutting off the filter abruptly when the volume lowers. This creates an excellent resonant analog "auto wah" effect which sounds as amazing on electronic drum loops, as it does on guitars, basses and keyboards.

The filter section is based loosely on the Korg MS20 synth filter. With the resonance low & envelope minimised, the unit will act as a very useful distortion device. Plus, again keeping envelope at minimum, it can be used as a tone control. It was designed primarily for tweaking loops & drum machines.

Settings:

Output Level

Sets the output level

Envelope (Down-None-Up)

Controls the amount & polarity of envelope modulation.

Input Range

Sets the input sensitivity, has major effect on intensity of effect as well as overall loudness. Important to set this so that when bypassing, the levels are about the same.

Res

Sets resonance of the filter. Can be turned up to actually resonate, either continually or when triggered by peaks of the input signal. This is one thing that makes the unit rather unique.

Frequency

Sets the filter cutoff frequency. It has a very wide range, so it is possible to have it set so NOTHING at all comes through. Also, when any of the other knobs (input, res, envelope, speed) are adjusted, the resonance freq moves, and needs retweaking.

Speed

Sets attack/decay of the envelope. When fully anticlockwise, the speed is FASTEST. Recommend using in this position, at least until one is familiar with the unit.

LP Filter / HP Filter

Selects the type of filter: lowpass or highpass. Unit will resonate in either mode.
