The LMN-3 is an open source portable synthesizer to compare to the OP-1 by Teenage Engineering. Open source software and custom PCB designed by Fundamental Frequency, machine designed and built by me in Los Angeles, CA.
The body is 3D printed and made out of premium PLA material (but can be printed with a more durable material such as PETG or ABS for an additional fee at your request). It includes a 4" LCD display, 24 3D-printed player keys and 21 3D-printed function keys on green Gateron MX switches, 4 rotary encoder knobs, and a pitch bender joystick. The device runs off of a Raspberry Pi 4 4GB.
The LMN-3 software includes:
- A digital synthesizer with customizable LFO, envelope, wavelength, etc
- 4 track recorder
- Sampler
- Drum sampler
- Step sequencer
Purchase will include a video tutorial on how to navigate and use the software.
PLEASE FILL OUR SPECIAL INSTRUCTIONS SECTION. Player keys, function keys, and body can all be printed in a variety of colors and types of materials (glitter, glow in the dark, UV activated). Please include your requests in the special instructions section and I'll do my best to match what you want and let you know if there's something I can't do.
*Units are built on request and require sourcing of a few components, so expect shipment within 3 weeks of purchase.
