Quad Function + Quad VCF​/​VCA - Demo 02 (COMBO​/​LPG Mode)

about

This demo is simply to show what the Sputnik Quad VCF/VCA (a Lowpass Gate) sounds like in its naked form. No effects or processing was used. It was only used in COMBO mode (where it attenuates both high frequencies and amplitude, like a lowpass gate).

Patch Details:

▪ 3 Waves (Sine, Double Pulse and Sub) from the Rubicon were mixed in a Manhattan Analog Mixer.
▪ The output of this was fed into channel 1 of the Sputnik Quad VCF/VCA (a Lowpass Gate)
▪ At points a Dixie Sine wave was used to modulate the PWM on the Double-Pulse, at varying frequencies.
▪ The Sputnik Quad Function & Trigger Source provided the short envelope which opens/ pings the lowpass gate. This was a particularly exponential shape, produced by sending the output of the envelope into a bipolar mixer - with the signal inverted - and then feeding a moderate level of this inverted signal back into the envelope's Decay CV input. This turns it from the default linear shape into an almost identical clone of the fantastic Make Noise Maths exponential curve.
▪ This envelope channel was set to output +8v - which can be set via a switch on the PCB (either +5v or +8v). It was fed into the Lowpass gate's CV input.
▪ The output was recorded direct.
▪ Throughout the recording I manipulated various controls, in order to give an idea of how the lowpass gate responds to different signal levels, types of waves, and different length envelopes. I used sines at points to demonstrate whether it overdrives at higher input levels.
▪ Towards the end I manually adjusted the cutoff/ bias control on the lowpass gate, to show how it responds to slower modulation.
▪ Right at the end I flicked on the Cycle switch on the envelope, and drove it into audio rates. Well, you've got to really, haven't you?

All in all I'm pretty impressed with this module. I have tested every output and input and have noticed no issues with it. It does the "Buchla Bongo" admirably well in my opinion, and is probably cheapest way to put 4 lowpass gates into your system. When combined with the Quad Function & Trigger Source, you've got a hell of a lot of timbral and rhythmic modulation bases covered.
