Melodic Randomness: Chance Delay & Dual RVG (Eurorack Probability & Random CV for Generative Patches)
video upload by AJH Synth Official
"Visit AJH Synth @MachinaBristronica (UK) Saturday 30th. Experimentation with using 2 random event & voltage generator modules within a melodic, sequencer-controlled, modular synth performance. Randomness/probability/chance can form the backbone of a generative music patch, but also in more manually controlled situations, and are a great companion for step sequencers.
Here a purely analogue step sequencer is used, with the time variation function of the Dual RVG serving as the master clock, and the Chance Delay adding probability to each step occurring. In the previous video the Chance Delay was randomly passing the gate signals from a sequencer to the synth voice it was controlling, so some steps would be missing. This time the module is placed before the sequencer, so that all steps will occur, in the correct order, but randomly. Since the gates it is receiving is from the master clock, all of the sequencer steps will remain in time with the music.
The Dual RVG also simultaneously produces 2 random control voltages for each clock pulse, and so I'm using one of these to modulate the frequency of the Entropic Doom, which I'm using to generate a simple percussive sound. The new Triple Cross module is also featured here, and cross-fades between 4 pitched drones, forming a melodic chord, but with 2 separate LFOs controlling the cross-fading, so that the mix between the 4 notes/sounds is constantly changing.
2 of the VCOs from the drone sound are passing through the Wave Swarm, creating a buzz of additional sawtooths to thicken their sound. These 2 are heard through the Fixed Filter Bank 914 later on, which creates a more choir-like timbre to accompany the output of the Triple Cross. The Sonic XV is used as both a filter and a wave-folder for much of the melodic sequence, where it is at times accompanied or replaced by the same VCO passing through the Ring SM and then Transistor Ladder Filter into Low Fat VCF.
Come see and hear the modules this weekend at: https://machinabris.wpengine.com
The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.
