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

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

  • 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.

  • 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.
  • More features than BulkyMIDI-32 and half the size!

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

Assembled Parts Include

  • Raspberry Pi 3 A+
  • 32GB SD Card
  • Custom MIDI "hat"
  • Long Micro USB Cable for Power
  • 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)
  • TRS 3.5mm Cable
  • A Stand

Does not include

  • Power brick - I recommend a 3 amp 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 .sf2 soundfonts or use your own by adding them to the soundfonts folder.

MT32-Pi Code

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. Github

Also compatible with MiniDexed!

Minidexed Controls Note:

Use the Minidexed build and config file here.

Use the knob and knob button to navigate, 1 click = select, longclick = back, double click = home

In Minidexed turning knob sometimes doesn't register that it should change right away but it works well enough. There is no such issue when using this as intended for an MT32 device!
