Music Thing Modular Radio Music

Open-source virtual-radio SD-card sample player

4 HP Eurorack module

Radio Music is an open-source 'virtual radio' from Music Thing Modular - a sample player that behaves like a radio dial rather than a conventional sampler. Audio files stored on an SD card are organised into 16 banks of 'stations'; the Station knob (or CV) tunes between them, and like real radio the files keep playing in the background so re-tuning drops you into a different moment. The Start knob sets a playback point recalled by the Reset button, which doubles as the bank selector when held. Built on a Teensy microcontroller, it is endlessly hackable, with a 2017 firmware adding wav and pitch support and many alternative firmwares (including Chord Organ).
