Hi

Nice projects, love the sequencer.

Your ideas for 3.3v should work, but if you use a level shifter  there is no need to sacrifice one LED.

I have experimented with an ESP32 as synth using mozzi, and a I2S DAC for sound out, but I also like the idea of wirelessly delivering Bluetooth audio to BLE speakers. Maybe one day…

If I’m not misunderstanding you a TTL 2 DIN midi is just a few components, (diode, resistor & optocoupler) and should be easy to add. LEET is built with MIDI over USB, but the devices should be easy to tweak if you want to add MIDI in or out.
