MT32-PI (MT-32 Emulator) Multi Timbre Sound Module, Full Build, 32GB, .sf2, Enhanced for Musicians

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. 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.

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 Lexar 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

Optional:

Stand which snugly places the MT32-pi at a nice angle.

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.

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.
