After the success of TSynth, 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
