Last week, I watched a YouTube video of @UndulaeMusic, where he created a full track using vcv rack in 1 hour (link: ). I was inspired by his workflow and decided to use a similar technique to his to randomize breakbeats. From there on I created ambiences and a chord progression, which I afterwards made playable with my midi controller. In this post, I will go over the most important parts of the patch.
You can download the patch and break samples here: https://drive.google.com/drive/folders/1yqsZ_fzrH53AwaNA-yQBzwhQqh7XAd8n?usp=drive_link
(press run on the CLOCKED module to let the breakbeat start)
(I left in the MIDI Map module, so you can see what I have mapped)
Patch Overview
The patch is built out of three main elements:
– Random breakbeat
– Chords
– Bass
Each of these is semi-generative (though randomization or LFO mapping to paramaters) but still controllable.
The Breakbeat
I used the WavBank module by Voxglitch, where I loaded chopped breakbeat samples.
I used multiple layers of clock division and randomization (which I learnt from this tutorial: (https)
CLOCKED (Impromptu) is the master clock
A Clock dividers (8:1, Bogaudio) is used to create variations, the output of this divider is sent into the trigger input of Wavbank.
A Randomizer is used to trigger the wave selection input of the wavbank
Afterwards I sent the break into the Detritus wave destruction module, afterwards into the SurgeXT Reverb module, and lastly into the Bogaudio VCF.
Chords (Ambient Layer)
The chord section consists of two layered pads.
The first pad, is generated with the Oscillators module by Mus-X that afterwards goes into a VCF and a VCA. The cutoff frequency is modulated by ochd LFO (Instruō).
The second pad is made with the Q106 Oscillator by synthesizers.com, that afterwards goes into a High Pass filter (to cut the unnecessary low frequencies) and it goes into the Gravy LP filter by Sapphire whose frequency and resonance is being modulated by the ochd LFO (Instruō) aswell. They also go through a plateau reverb send I have on the mixer.
To make different chords, I used the PGMR module by Bogaudio (a 4 step sequencer and voltage programmer), which I afterwards sent into the Quantizer module of VCV rack (12-note quantizer and scale selector). You will send the output of this Quantizer module to either a V/octave input or any frequency related input of the oscillator
I trigger these different steps with the trigger pads that I mapped to my midi controller using the MIDI Map module.
Bass Voice
The bass is generated by two oscillators; Wavetable oscillator by tiny tricks layered with the stock VCO of Vcv (a simple sine wave that functions as a sub).
In the wavetable oscillator I modulated the position of the wave with an LFO.
The bass is pretty simple, there is not much going on.
Playable Instrument/ Midi mapping
To make the patch more performable, I mapped these parameters to my MIDI controller:
Filter cutoff on several elements
Reverb amount
Wavbank sample select knob
PGMR Sequence trigger
