Introducing the MT32-Pi, hand crafted, fully assembled and ready to use. Sounds amazing! Full bare metal hardware.

Small code improvements have been made, with more code improvements planned.

Code improvements: Clicking encoder button (knob) shows the currently active soundfont. Clicking encoder button (knob) twice displays the internal Pixel Pet.

Ready to plug in and play, designed for musicians. Compact form factor. Also compatible with MiniDexed!

Better latency and faster than the devices built with the Pi Zero 2 W! 40% faster CPU speed! 4 x 1.4 GHz vs. 4 x 1 GHz. Get it in any color you like. Lower cost!

This unit does NOT require a mister FPGA and is fully standalone.

Assembled Parts Include:

Raspberry Pi 3 A+ 32GB Lexar SD Card Custom MIDI "hat" Long Micro USB Cable Full Custom Shell Rotary Dial (Volume) and 2 Buttons for switching between Sound fonts or ROMS. LCD Screen High Quality Audio out DAC TRS Type A MIDI (in, out, thru) Stand (optional)

Does not include: Power brick - I recommend at least a 3A compatible USB brick.

This device not only mimics the MT-32’s signature sound but also supports soundfont emulation for a variety of soundfonts. Experience classic retro audio with this solution, which delivers authentic MT-32 and general MIDI sounds while costing considerably less than the original hardware. It can be easily connected to new or older computers equipped with MIDI out.

Can play Soundfonts with a MIDI keyboard in fluidsynth mode (default): Use up to 16 MIDI channels with up to 128 programs. Comes with a variety of soundfonts or use your own by adding them to the soundfonts folder.

I have added a Pixel Pet to keep you company while composing, with several randomly changing animations.

I have published a version of MiniDexed that works on this mt32, just need to extract the contents of the zip to a FAT32 formatted SD card. Use the knob and knob button to navigate, 1 click = select, longclick = back, double click = home Turning knob sometimes doesn't register that it should change right away but it works well enough. https://github.com/eggstoastbacon/MiniDexed-MT32/releases/tag/beta
