"Jeannie" 8 Voice DIY Teensy Synthesizer by Rolf Degen

Rolf Degen

The project is currently on https://forum.pjrc.com

"I am currently developing a new DIY synthesizer based on a Teensy 4.0 Boards. The synthesizer will look similar to the small Shruthi Synthesizer from Mutable Instruments. Compared to the Shruthi this synth will be polyphonic, have a color TFT display and other things like a 2Channel 16Bit DA-Converter, digital and analog filters. The housing and board format is similar to the Shruthi (see picture). That's why for the DIY Project I also created the Name 'Shruthi 2' selected."
