"Electrotechnique Momentum - 12 voice virtual analogue, digital polysynth - DIY or buy.
All sounds from Momentum using built-in effects. Multitracking, EQ and panning on Ableton Live.
Momentum uses a PJRC designed Teensy 4 microcontroller platform on a Sparkfun designed Micromod: https://www.sparkfun.com/products/16402
Available on Tindie: https://www.tindie.com/products/elect...
Github repository: https://github.com/ElectroTechnique/M...
Thanks to Time Travel [TT] for inspiration."
"After the success of TSynth [see previous posts here], Electrotechnique brings you Momentum.
Momentum is a powerful, low-cost, 12-voice digital virtual analogue polyphonic synthesizer. It’s features rival those of synths costing many times more. Momentum builds on TSynth, Electrotechnique’s first synthesizer and adds additional features.
Sound:
12-voice polyphony, velocity sensitive
Stereo analogue audio plus 16 bit 44.1kHz digital audio via the USB port
2 oscillators and state variable filter per voice, with comprehensive modulation
Stereo ensemble and reverb effects
Three Simultaneous MIDI ports:
USB HOST MIDI Class Compliant (direct connection to MIDI controller, no PC needed)
USB Client MIDI In from PC
MIDI In TRS —supports both type-A and type-B TRS leads
MIDI Out/Thru TRS - configurable as a MIDI Thru with filtering options
Patches, Performance, Arpeggiator and Sequencer:
8 user banks with 128 nameable patches, recallable via MIDI
128 performance memories—store patch and choose parameters for encoders to control and MIDI settings, recallable via MIDI
Simple step sequencer with up to 64 steps and 128 sequencer memories
Arpeggiator—simple arpeggiator with six styles, choice of ranges, base octave and tempo divisions
Simple 8 note polyphonic keyboard with scales and octave choice
Storage:
Removable SD card for patches, performance and sequence memories
Momentum is easier to build than TSynth and has a simpler case consisting of a 3D printed tray and a PCB front panel. The software is open source and user development is encouraged - TSynth gained new features from users.
Options
Momentum can be purchased as:
a full kit including components and case, but without a Teensy Micromod or Micro SD card. This can be bought from Sparkfun directly or another source if you wish. Micro SD cards can be bought everywhere
a full kit with a programmed Teensy Micromod and Micro SD card
fully-built and tested with Teensy Micromod and Micro SD card"
