The TronPi - A Raspberry Pi Mellotron Emulator

The TronPi is a Mellotron emulator, based on the $35 Raspberry Pi computer.

The TronPi has the 4 classic Tron sounds: Choir, Strings, Brass and Flute. The TronPi is controlled with a standard USB/MIDI Keyboard and doesn’t have any perceptible latency.

All the audio in this video was taken straight from the Raspberry PI’s audio output, no further processing was added to the source. It’s straight out of the computer. The reverb ambience you hear on the recordings is built in the sampler and adjustable.

The computer boots in 30 seconds or so. It supports MIDI program changes and once loaded, program changes are instant, no lag.
