Patch Notes #26 - Generative Eurorack Jam


Published on Nov 25, 2016 Voltage Control Lab

"Exploring a generative patch using the Ornament & Crime Turing Machine mode along with some slightly randomized drums from the Varigate and some smooth tones from the DPO and Clouds.

The Ornament & Crime is in Quantermain mode, generating a single Turing Machine on channel D, clocked by the Make Noise Tempi and Turing probability modulated by a channel on Analog Memory. Tempi is also clocking Brains and Pressure Points, one channel of the connect Analog Memory module is routed through channel 3 on Maths, and then into the Ornament & Crime CV4 input.


This is the crux of the generative voice. The slowly stepping Analog Memory switches the O&C 100% chance of a randomized value on one step, then around 5% chance on the next step, and 0% chance on the last two steps. This means every 4 bars or so, the phrase is randomized to a degree.

The generative sequence is routed to the Make Noise DPO, onto the MMG filter via the Final output and then to the Optomix. The signal is then passed through Mutable Instruments Clouds running the Parasites firmware in Oliverb mode (updated this easily via the SpektroAudio ALTRNT website), and on to the Malekko Mix4 and out. The Malekko Varigate 4 is triggering an envelope on the AD/LFO, which is opening the Optomix.


Clouds is being heavily modulated. A sine wave LFO from the TipTop Audio Z3000 is modulating the decay time control, while the triangle wave is modulating the pre-delay. The right output from Clouds is fed back into the Z3000 waveshaper input and the sine wave out from the DPO modulation oscillator is routed to the FM input as well, further complicating sine and triangle waves. The stepped and smooth random outputs from the Make Noise Wogglebug are also modulating Clouds reverb size and damping filter respectively.


Tempi is clocking and resetting the Varigate which is already triggering the generative voice. In addition, one channel is triggering the Noise Engineering Basimilus Iteritas which is acting as the snare. The BI is then passed through Mutable Instruments Warps in Parasites firmware delay mode, and out to the Mix4.


The kick and hihat are both sequenced on the Varigate as well, triggering the Roland Scooper via a few envelopes on the ADLFO.


The bass is sequenced via the DU-SEQ (clocked by Tempi), which is playing Mutable Instruments Braids. A looping envelope on the Intellijel Dual ADSR is modulating the Braids color input, giving some motion to the bass tone.
