The MIDI FORGE Maestro emulates a wavetable board for vintage sound cards.

A Raspberry Pi Zero 2W is used to emulate wavetable sounds using sound fonts or a Roland MT-32 device.

The SD card needs a configured copy of the mt32-pi project (by Dale Whinham) found here: https://github.com/dwhinham/mt32-pi

Some of the connectors have to be cut to size:

Front-Panel connector: Usually comes in 1x40P - you need to cut 9P for the MIDI FORGE Maestro

DAC (1x4P, 1x6P), OLED (1x4P): The SMT single row header might also only come in 1x40P. Cut 2x4P and 1x6P.

OLED Display:

The OLED displays from PCBWay have no pins soldered to the PCB - that makes it much easier to assemble:

This project is DIY! Due to the unconventional way how to place component on top of each other, assembly services from PCBWay will probably not be possible.
