Quatrain and Boost - Delay pedal feedback patch

video upload by DecadeBridge

"Quatrain comes with Boost. A dirty pre-amp/distortion effect.

Boost can be used with Quatrain to create a feedback oscillator.
Here I'm using them and two cheap guitar delay pedals to create a variety of drones, noise and texture patches."



via DecadeBridge

Quatrain ships with Boost which is a dirty preamp/distortion effect that can also be used with Quatrain to create a feedback oscillator.

knob style and colour may vary depending on stocks.

Quatrain is a passive 4 x 4 Matrix Mixer that can be used in a eurorack system or standalone. It allows you to mix CV or audio signals together and then adjust the amount sent to the 4 outputs using the 16 pots.

Quatrain is passive and draws no power from your eurorack system.
Eurorack size - 24 HP

Features:-
4 inputs for Audio, CV or feedback paths (4 switched inputs for rows 3 and 4).
4 Outputs to route the input signals to.
4 x Linked attenuators to change the amount of the signal sent to two outputs with a single pot.
16 Attenuators.

Mute switches for inputs and outputs.
Compatible with eurorack dimensions.

When using with a eurorack system the back plate doubles up as a blank panel with some gorgeous artwork from https://www.instagram.com/jack_sl0w/

HAP - Eurorack dual Bernoulli gate logic utility

video upload by DecadeBridge

"In this patch I'm using HAP to trigger 3 Prok drum modules, 4 Rample samples 3 envelope generators and seeding Mutable Instruments Beads. The trigger input is taken from Pam's pro workout through the Coeo passive mult. One of HAP's outputs is also sent through Coeo to gate the doepfer A140 and 1 of Rample's samples.

HAP is a 1 in, 10 out, dual Bernoulli/AND gate logic module for eurorack. When HAP receives a gate or trigger at it's trigger input it randomly selects (based on it's settings) to set one of it's outputs high (2 x 2 Bernoulli gates).

It features probability (1|2) and Skip for both Bernoulli gates and switchable CV inputs for both controls.

It also features 5 AND gates that are set high depending on the state of the Bernoulli outputs and 1 extra random output that is on or off for 50% of the time."

Chance/Microcosm jam

video upload by DecadeBridge

"Chance is a random note generator for the ZX spectrum using its crude beep function. I've set it here to choose random notes from a major scale. I'm then running the spectrums output into the Microcosm which is set to Arp chopping the longer notes from the Spectrum down. I'm then using the phrase looper to layer up the audio from the spectrum, looping and overdubbing."

Noria - Jam

"I've been re-visiting Noria when I get chance. Here is the latest revision. Pam's pro workout is clocking Noria. All other elements (sequences, Beat triggers, envelope gates) are controlled by Noria."

DecadeBridge Prototypes 2024 (so far)

video upload by DecadeBridge

"Jump to the time stamps below to skip through.

A few things that have been on the Decadebridge prototyping bench the first half of this year.

I like to give these things names relatively early on in the process to remain focused on the idea itself. That doesn't mean it doesn't evolve through the process but it does help cut away any unnecessary functions and the heart of its meaning doesn't give in to the overwhelming options that could, potentially, take away from it's character.

00:00 Laconic running through a low pass filter and some stereo delay. pitch controlled with Turing machine and volts. Volume controlled using a EG triggered by the Turing machine pulse out.

00:53 Laconic. Disting Mk4 controlling pitch. Manually changing settings.

01:45 Laconic. Pitch controlled manually and with the Turing machine and volts.

02:59 Laconic. Pitch sequenced using SQ1 and Moog subharmonicon sequences. All sounds from Laconic. Subharmonicon envelopes controlling voice level.

03:58 Noria. Ongoing, analog style step sequencer project.

06:49 Untitled. Just playing around with a glitchy, Sid chip type sound. 4 step sequencer that quickly turns into erratic dronal stabs. Fun little project.

08:18 Quatrain. 4 in 4 out passive matrix mixer with a few extra bits. Creating drones with feedback paths. the only sound sources are a couple of cheap guitar pedals (reverb and delay).

11:42 Quatrain. Using the mixer in a Eurorack setup mix CV signals.

13:31 Quatrain. Pure feedback paths to generate drones and tones. Korg amp works, Behringer vintage delay and digital reverb all feedback into each other and themselves to generate drones.

16:13 Quatrain. More CV input mixing and playing on Quatrain's other qualities in this eurorack patch."

"Sn is a lofi FM synthesiser that can produced a wide range of tones, textures and noise. This video demonstrates some of the sounds when operating alone.

It features 7 algorithms, with 3 different pitch settings for each. Controls for Carrier pitch, modulator pitch(es) and FM amount. Each control also has a CV input and a trigger/gate input is available to change algorithms. The output is run through a passive LPF that turns into a LPG when the passive VCA is on and a CV signal is received at the VCA's input."

The algorithm selection can also be stepped using a trigger/gate signal.

Carrier pitch with CV input.
Modulator pitch(es) with CV input.

Albers - CV inputs Pt 2

video upload by DecadeBridge

"The version of Albers available to customers has a few more features than the one in this video including:- LFO outputs.
LDRs can be switched to control Oscillator pitch or LFO rate.
3 way range switch for Oscillator pitch instead of 2.

This is a quick chiptune style jam using Albers as the only sound source. Stereo delay has been added in Albers. Albers' oscilator volumes are being controlled by several triggers and an envelope generator. The pitch of oscillator D is being controlled by an envelope generator and the filter cutoff by the Turing Machine."

Albers - Stepped tones.

video upload by DecadeBridge

"Using audio rate oscillators patched into Albers' pitch inputs and then using the LFOs to create stepped tones. In the first part I use all four of Albers' oscillators as stepped tone generators and then have a little jam with the patch. In the second part I use a VCO to create two stepped tone generators with oscillators A and B and then use the other two as sustained notes. This is followed by another small jam with the patch.

00:00 - Patching Pam's pro workout (outputs 5 - 8) to Albers' pitch inputs.
02:58 - Adding more elements to the patch whilst having a jam. Delay has been added in Ableton.
07:38 - Using the square and saw wave outputs from the Moritz Klein VCO patched to Albers' oscillators A and B whilst using C and D to add static notes. Stepped tones and drones.
09:11 - Adding more elements to the patch whilst having a jam. Delay has been added in Ableton."
