This is a Minidexed with Raspberry Pi 3B using a PCM5102A module, a Pico RP2040 PC USBMidi-Interface, and a 6N137 Midi 5pin DIN Input
This is another variation of the Minidexed DX7-Synth by Probonopd and Circle which runs the RPi as a if it is an MCU.
It uses the excellent snap-close 3d-printed case presented by dhstsw here, and the top and modified bottom (the trimpot was replaced with a 6N137 Midi Interface and a 5pin DIN socket added) STL files are in the STL folder. The modified case here is still a WIP.
The Pico and Minidexed Tx-Rx Midi interface is discussed here.
