Original Braids
- AN ATLAS OF WAVEFORM GENERATION TECHNIQUES
- Braids is a voltage-controlled monophonic digital sound source.
- Sound source… like an oscillator? Not really.
- Most of the timbres it generates are so complex that approaching them with a classic analog modular setup would require a full case of oscillators, filters, VCAs, waveshapers and ring-modulators – that’s why we call it a macro-oscillator – intricate digital synthesis algorithms wrapped in oscillator’s clothes.
- 2 KNOBS TO RULE THEM ALL
- Each algorithm is controlled by two continuously variable parameters, TIMBRE and COLOR, both of them voltage controllable.
- Instead of being directly assigned to the intricate details of the synthesis algorithm, they work as meta-parameters going through all the sweet spots.
- Very often, these parameters simultaneously affect several dimensions of timbre, creating very complex movements which would be hard to generate with a traditional setup.
- 16 HP
- 25mm deep
- +12V@100mA, -12V@15mA

- Get the PCB set with panel and both PCBs for 9$ at Kristian's Tindie store
- Tindie store
- (Or) Download the Gerber files
- 5pcs Red Common Cathode 7 segment display - MAKE SURE TO CHOOSE COMMON CATHODE
- Get a STM32 Programmer here
- STM32F013CBT8 (128kb version) on ebay... not that many to choose from :/
- The STM32F103C8T6 is the 64kb version and thus too small but SOMETIMES they are 128kb
- Front panel gerber by MyModularJourney
- Braids illustrated. all the waveforms explained
- Emilie Gilet / Mutable Instruments modules Github
