This is a sound module (a MIDI expander) ; it converts MIDI into audio. You can use it with any device that has a MIDI output (piano, synth, MIDI controller, etc).
The hardware is a simple Raspberry Pi A+. If you already have one, just order the firmware or SD card ! The firmware reads SF2 files, MIDI mapping/bank assignments and audio settings from the SD card, and loads them into a software synthesizer. The result is that you can edit and play your own SoundFont collections, in a tiny, cost-effective device.
Personally, I designed it because 1. I love my 88-key Roland, and I wanted to expand it with classic synth sonorities. 2. I wanted to try experimental SF2 sounds of my own. 3. I usually had to mess up my PC audio server each time I played piano. 4. I needed a portable device, to bring it to band rehearsals.
Don't look for buttons, there is none. Instead, use the "Liane" Python configuration tool on the SD card : For each MIDI channel (max 16), you can assign one sound (SF2 file, bank number, program number). When playing music, just switch MIDI channels from your controller, and the expander will play the corresponding sound.
