This is awesome, always wondered how to build one of these! Also I love the ESP32 as well! It's definitely suited for more IoT projects and really good for wireless wearables. If only physics would allow us to have less latency 😆

Embedded developer here that uses Espressif microcontrollers like the ESP32 daily, don't worry about being annoying when complaining about the ESP line's wireless latency. It's real and we all have to deal with it, even with pushing packets over WIFI using UDP. It's just not something Espressif worries about over ease of use and stability of the wireless connection. Hardware connections will always trump over the air, sadly. This is also something that plagues the enthusiast keyboard market. Getting gamer-ready performance + wireless is a serious issue and it seems companies are gravitating towards microcontrollers from Nordic. Weird bluetooth latency spikes still apply though. Maybe things will be better with future hardware (and library) revisions but I'm not holding my breath. Nearly all IoT applications can withstand latency that would be killer to a musical input tool or game controller while Teensy or STM microcontrollers seem do be fulfilling the musical demand just fine.

How about making a midi device that controls a human foot going in time with the rhythm. Then sends little electrical impulses to the toes to indicate notes beyond 8th notes. Now that would be a real breakthrough. Triplets, quintuplets, mixed in rests. That’s what we need. Don’t get me wrong I appreciate what you’re doing but I bet you could do something more on the breakthrough level if you put your mind to it. Even lights that blink in time that would be a good way to start. Taking the data out and using it as opposed to trying to put data in.

Hey! Quick question… for purposes I’m making a controller to hook up to my Mk1 octatrak to play in some samples - same as you. I have a Kenton MK3 usb host that acts as a host and converts usb midi controllers traditionally for computer to 5 pin midi. My question is will the Raspberry Pi Pico (RP2040) with this build and code be hosted by my Kenton? The chart in the link says the pico has MIDI over USB (device) but not midi over usb (host)… am I right to say that the Kenton would be the host and it would pick up the pico as a device ? Super broke dad so I’m tryna keep my costs lower than the beautiful ground. Thank you!!

Yes, device receiving MIDI messages is the host. I don’t have a Kenton but I imagine it should work without any alterations to the code. Good luck with your build!

Thanks for watching! The arcade buttons are around a dollar each on Amazon and the boards are ~$5. In all, I'd say it's around $30 if you have the tools and an enclosure. There are links in the description for most things. For the coding it took around 2 days to code, build ,and film the video. I leveraged some APIs I've used in the past.

Is it showing an error in the Arduino console when you try installing the build to your Pico? Did you also install and add the Control Surface library in the Arduino IDE too? Does it seem like it is installing but MIDI isn't being detected? I think the logs in the Arduino console will give the best clues as to what is going on.

There doesn't seem to be a clear, documented way to change the name. On Mac you can give it an alias in in the Audio MIDI Setup app > MIDI Studio. Or you can edit the name of the board in boards.txt, but that name only shows up in Arduino. I'm sure there has got to be a way to do it. Hopefully it'll become more clear in the future.

As long as the sound generation happens on the device while playing, it's fine, but if you try to use these devices as midi controllers for vst synths, the experience hurts due to the bluetooth latency.

@@dodom2863 While faster/more stable than midi-over-bluetooth, usb-midi can still create lag and timing issues when it comes to synchronized lighting (like strobe rates, moving heads syncing , etc). I am learning this now myself as I prep to outfit my Roland drum kit with sync'd UV lighting under the heads, and the guys helping me have said that (old school DIN connector) midi-serial is THE way to go for MCUs. Just requires a few parts and soldering to create the connection from the 5-pin midi jack to your MCU, and of course, your computer would have to have a midi output, which many music-minded folks might have in their audio interface. If your PC doesn't have a midi output (and you don't wanna buy one), then try "hairless midi". Check the "engineering mindset" channel for tips on serial-midi input construction. Also, if you go the arduino route, check out Lady Ada's MCU lessons. Good luck!

Hey, sorry for the delay! Yeah, you could use pots with the ESP32 but I've not made any projects with ESP32 that use them.

Like I said, I've not done it with ESP32 but it is a pretty general feature of most boards.
