- Quirks is an utility module that provides 3 signal processing operations based on Mutable Instruments' Kinks.
- Quirks is sold individually and as part of Malleable Instruments Bundle.
- SIGN SECTION
Inverted output. Besides the typical CV applications (invert the direction of an envelope or LFO), inverters are useful for creating interesting waveforms from VCO outputs.
For example, invert the sine output of a classic analog VCO, and mix it with its sawtooth (or triangle) output. This is equivalent to attenuating the fundamental frequency of the
sawtooth (or triangle) waveform, creating a more nasal sound. Half-wave rectified output. The negative half of the signal is clipped to 0V. This can add many harmonics to audio signals. Full-wave rectified output. The negative half of the signal is inverted. On symmetric waveforms like a sine or a triangle, this doubles the frequency of the signal (“octaver” effect). Another interesting application is to pre-process a random signal before sending it to a quantizer or digital VCO - some of these don’t handle negative CVs! The monitoring LED indicates the amplitude and polarity of the input signal.
- LOGIC SECTION Signal inputs, normalized to 0V. Analog OR signal (maximum, peaks). Analog AND signal (minimum, troughs). The monitoring LED indicates the amplitude and polarity of the sum of the two input signals. A few interesting observations: Since the inputs are normalized to 0V, if you patch a cable into only one of the inputs, MAX will output the positive half of the waveform, and MIN will output the negative half of the waveform. You can of course use these for manipulating digital triggers, gates or clocks. With audio-rate signals, the resulting waveforms have the same kind of inharmonic partials and side-bands one would obtain with a ring-modulator. A classic “Buchlaesque” application is to combine various AD envelopes or triangle LFOs to create very complex shapes. Another interesting patch is to use a slow LFO to clip a triangle or sine wave creating a PWM-like effect.
- S&H AND NOISE SECTION On each trigger received on the TRIG input, the output voltage takes the value of the input voltage and holds this voltage until a new trigger is received on the TRIG input. Signal input, normalized to the white noise generator. Trigger input when >=2.5V. Noise generator output. Sample and hold output. The monitoring LED indicates the amplitude and polarity of the output signal.
