Any MIDI heads out there have a recommendation on the cheapest way to get a programmable MIDI processor box? Is there something out there that has MIDI In/Out and a programmable microprocessor?

I’m looking to have something that delays Program Change messages, with a delay speed calculated by the rate of incoming MIDI clock messages. I have the algorithm figured out, and just need something simple to implement it on. #askfedi

@chorist one of these "RP2350-USB-A" things:

@tecteun I’ll look closer, but I need something without USB needs… this thing is going to sit between a hardware sequencer and a synth, no computer.

@chorist usb device side can be power only, and use host to get midi din in/out, or without usb (any rp pico would do) I found these very elegant:

@tecteun That does look neat. I’m pretty novice on the hardware (as opposed to software) side of things so some of this is a little unknown to me. I’m looking at this (https://www.adafruit.com/product/4740) along with one of their dev boards… Seems like about $20 all in? And more beginner friendly? But outside of Adafruit I’ve barely ever bought hardware components for personal projects, for context.

@chorist any pico would be good, as you can choose to use micro/circuit python (very easy to maintain) or the arduino ide/c. This adafruit feather stack seems like a great choice, and not expensive, good support 👌
