"18 minutes of random wiggling with the FLITZEM DEFÖR Sequencer being triggered from the Westlicht PERFORMER. The Oscialltors used are 2x Cyllene and 1x GIVE II.

Yes, there are some atonal and dissonant passages here, but thats part of the game when wiggling around. Any quantizer would solve that immediately (just didnt have one at hand)."

ST Modular - STEREO COMPRESSOR with Boba Fat, HH, Pyxis and Phoebe

Stefan Tretau

„Stereo Compressor“ is a classic analog feedforward compressor, which takes its sidechain split directly from the input signal. It is based on the THAT4305 Analog Engine® single-chip with integrated Blackmer® VCA. It has two independent signal paths in order to process stereo signals. The left input is normalized to the right, if you want to compress mono signals instead. The module has three controls and a switch:

THRESHOLD determins the level at which the compressor starts working. This can be set from -40dB to 20dB.
RATIO sets how much the compressor turns down the volume when the threshold is reached (INF:1 to 1:1).
GAIN regulates the amount of make-up gain (-20dB to +20dB) that is applied to the signal.
Additionally there is an ON/OFF switch that makes it easy to compare the dry and compressed audio signal.

Please note that if you turn THRESHOLD counter-clock wise to the left, you reduce the threshold from 20dB (fully cw) to -40dB (fully ccw). Hence the compressor starts working earlier. If you turn RATIO counter-clock wise to the left you increase the amount of compression from 1:1 (fully cw, no compression) to INF:1 (fully ccw, infinite compression). So turning the knobs down corresponds to compressing the signal. The pictures below show the knobs in a neutral position where no compression is applied.

STEREO COMPRESSOR has a similar design as the STEREO SUM CHANNEL modules. If you want to add some compression to your mix STEREO COMPRESSOR is a perfect addition to your STEREO SUM Mixer.

ST Modular - CV SCAN, TRYFELO and EUROKASTLE


"Using CV SCAN to scan through different CV sources from Tryfelo to control EuroKastle Pitch. And using CV SCAN to route one CV source from Tryfelo to different CV inputs of EuroKastle. Scanning manually and via CV, using the Volt Output of CV Scan to change EuroKastle CV with the Scan knob and interrupting the CV SCAN route via gate signals and manually via the dedicated OFF button.
I´m also using the new Balanced Output Module "UIT" here.

This is not supposed to be musical ;-)"

ST Modular - Rocinante´s Gate

Published on Dec 16, 2019 Stefan Tretau

"LPG with Envelope Generator and LFO

Rocinante´s Gate is not a classical low-pass gate (LPG) using vactrols, but goes way beyond that providing an adjustable envelope to control the "gate" through an analog filter. Sending a gate or trigger signal into the GATE INPUT will create these envelope shaped sounds you know from other LPGs.

The LOWPASS knob adjusts the range of frequencies being affected by the gate. If you turn it fully counter clockwise the whole frequency spectrum will be gated. Turning it clockwise will slowly add low frequencies to the gated singal until the whole spectrum is not affected anymore.

ENV AMT sets the amount of how much the internal envelope affects the low-pass gate. RISE sets the time how long it will take the sound to go from silent to the loudest level. Just like the time it takes the LED insight of a vactrol to start lighting to its full potential. DECAY controls how long it takes to go from an intial peak to the "gate-phase" level. The length of this phase is varied by the LENGTH potentiometer. Finally FALL changes the time your sound will need to return to silence after the "gate-phase". Just like the time it takes the LED insight of a vactrol to shut down.
RESONANCE sets the amount of filtered audio being fed back into the filter input. It can´t go into self-oscillation, but is able to create very crunchy and juicy overtones when turning clockwise.

The internal Trigger Generator is being controlled with TRIG RATE and the RE-TRIG/LOOP SWITCH. Adjust the rate of the trigger and apply the singal to either a re-trigger circuitry that repeats the "gate-phase" as long as a gate signal is being applied or to a loop functionality that will create cycles of gates without an external gate or trigger. The ENV/INV SWITCH enables you to alternatively route an inverted envelope to the low-pass filter. This way you may create "ducking" or "side-chained" sounds.

An internal triangle LFO can be routed via the LVL ATT attenuator to vary the amount of envelope that is being passed to the gate. The LFO will be deactivated if you turn the LVL ATT attenuator fully counter-clockwise or if you use an external signal to control the envelope amount by patching a CV signal into LVL CV.

In addition to the Audio IN and OUT jacks you may take the signals of the internal envelope and LFO from the ENV OUT and LFO OUT to controll external devices. In combination with the loop function Rocinante´s Gate is not only a Low-Pass-Gate, but also an LFO and ADSR Generator.
