joeSeggiola | Terry Riley - In C - Modular synthesizer performance using a DIY module @joeSeggiola | Uploaded February 2020 | Updated October 2024, 1 hour ago.
Made in February 2020 with Eurorack modular synthesizer and Minibrute 2.

The system implements five separate synth voices (shortly described further down), plus the eighth note pulse. CV/gate for every voice is provided by a custom-made module powered by Arduino (link below), which is controlled using manual buttons to advance through the 53 melodic patterns of "In C".

Bass (1) is from Minibrute 2 double VCO, with both on-board VCF and VCA controlled by the on-board ADSR. Mild resonance and Brute Factor are used to shape the tone.
Mid-bass (2) is from MFB OSC-02 third VCO. It is filtered by WMD/SSF Pole Zero with an ADSR envelope from Stages, which is also used to open a VCA in Veils.
Mid (3) is from MFB OSC-02 second VCO. It is filtered by Bastl Cinnamon in band-pass mode, with slight distortion (drive plus character). The AD envelope from Pico MOD modulates the VCF and open the VCA in Veils.
Mid-high (4) is from MFB OSC-02 first VCO. Maths CH1 is used to open the first LPG in LxD, sometimes configured like a normal AD envelope, other times like a ramp LFO. The output signal is sent through Pico DSP for a tempo-synced echo effect.
High (5) is a looping stage from Stages used as a VCO. It is not filtered. The VCA in Veils is controlled by the spare AD envelope on the Minibrute 2. Notes are occasionally randomly skipped, by filtering gates with a Branches clone module. The output signal is sent through Pico DSP for a tempo-synced echo effect.
The eighth note pulse is ModBox Skew LFO used as a VCO, passing through the resonant LPG in LxD opened with Maths CH4 (which is also used as a master clock signal). The S&H from ModBox is scaled in Stages and used to randomly change the pulse volume in Veils.
The audio mix is sent through a couple pedals for reverb and optical compressor. A stereo-widener VST is used to process the mono signal.
