ST Modular - MIA 2x2 Channel Mixer

Published on Feb 6, 2020 Stefan Tretau

via http://www.st-modular.com/mia.htm

Details:
•2x2 Channel Mixer
•Volume Control for each Channel
•2 Channel Fader
•Fader Volume
•Wrong polarity protection
•Skiff friendly
•3U Eurorack module, 5 HP wide
•Power consumption: 35 mA at +12 V and 25 mA at -12 VThe module consists of two boards:
•Front PCB Panel
•Main PCB

MIA 5HP 2x2 Channel Mixer with Fader MIA is a fairly simple, but very handy 2x2 channel mixer with an optional fader output. CH1 & CH2 have two input jacks with VOLUME control potentiometers each. The signals inserted here will be mixed and supplied at the CH1 & CH2 outputs. Simultaneously the signal will be routed to the FADER. The summed signal of channel CH1 & CH2 will be available at the FADE output. Using the Fade potentiometer you may mix the two channels to taste. The overall FADE volume may be adjusted using the FADE VOL potentiometer. If there is a cable plugged into the IN A or IN B jack, the connection of the mixer channels to the FADER is interrupted. Thus you can mix 4 sound sources and fade two additional signals at the same time. Originally this mixer was designed to mix several VCO waveforms with the ability to route each of the mixed signal (from CH1 OUT & CH2 OUT) to external modules, such as effects and filters, and then again mix the externally proccessed signals (using IN A & IN B) to one single output (FADE out) via the fade circuitry. In some cases it might even serve as a stereo mixer.

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.

Just a Minute - GIVE II VCO melodying

ST Modular GIVE II posts

Some info on the module via ST Modular

"Give II12 HP Classic Analog VCO with additional Frequency Divider and Waveform Mixing OptionsIt is not a substitution for GIVE I, but rather another version as it is based on the same core circuit. Actually both versions complement each other very well building a powerful complex oscillator.The VCO provides five outputs, the last four of them can be mixed with an integrated mixer: PULSE, SAW, TRIANGLE, 3x PULSE SUB & NOISEPatching a voltage/audio source into FM you can frequency modulate the oscillator. Incoming voltages can be attenuated with FM CV. In the middle of the module you will find the PWM potentiometer. Here you may change the pulse width of the pulse wave. The width may also be controlled via external voltage with the PWM jack and the PWM CV attenuator.Just like all other classic analog VCOs GIVE II also tracks one volt per octave with the help of the 1V/OCT input jack. Each wave can also be hardsynced by an external wave patched to the SYNC jack.In addition to the classic VCO functions GIVE II also provides an integrated frequency divider. The MIX output jack will not only supply the waveforms SAW, TRIANGLE and NOISE, but also provides up to 3 sub octaves derivated from the PULSE waveform. The volume of each suboctave may be adjusted with the potentiometer SUB 1-3. ORIG will adjust the volume of the original PULSE signal. Using the switch ORIG SQU you can flip the SQUARE waveform."

ST Modular - EFI (4HP Analog Filter)

Published on May 4, 2019 Stefan Tretau

"Dual-Mode Analog Filter

EFI is an analog multi-mode filter that is loosely based on the KORG MS-20 filter, but has been improved to fit into a 4 HP module.

It has a Low Pass and High Pass Mode which you may choose via Switch on the front panel. Additionally there are two CV inputs with an attenuator each.

Resonance can self-oscillate and there is a third mode that you may choose via jumper on the back. In this mode Resonance will be overdiven very quickly in Low Pass Mode and you will get some nice liquid sounding overtones.

This module is very easy to build and only needs 24 different components that are quite easy to source.

Details:
• Analog Dual-Mode-Filter
• Filter Modes: LP, HP (+ LP Overdrive via Jumper)
• Resonance Control
• Two CV Inputs
• Two CV Attenuators
• Wrong Polarity Protection
• 3U Eurorack module, 4 HP wide

The module consists of two boards:

• Front PCB Panel
• Main PCB

"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)."
