Thanks a lot for this!<p>I've done this before manually to convert an Arturia Minilab MkII into a wireless MIDI controller. Turns out there's enough space inside the Arturia to fit a Pi Zero W and a flat Lithium-Ion battery.<p>I can now use GarageBand on my iPad, MacBook and iPhone without always having to connect a USB-C hub or camera adapter.
Oh, man, I'm glad you cracked this. I spent days getting the Neuma stuff to work and I think I finally got it sorted out, but it was such a bear that I didn't bother sharing it with anybody else.<p>My own use case for this is that my main synth tool is my 2nd gen 12" iPad Pro, but I hate having to deal with the Camera Connector and the irritating fact that it won't recognize my higher wattage USB-C power adapter and USB-C to Lightning cable. So if I want to use it for any length of time I have to use the factory power wart, which actually loses power if I'm running the iPad at full brightness and using a lot of CPU on synthesis. Which makes it really annoying to work on stuff for long periods, and I can't plug in my iRig Pro and a synth unless I'm using a powered USB hub.<p>But this is great. I can just keep the Pi running and hooked up to the synth, even power it off a USB power pack for doing stuff on the go. Thanks for sorting this out!
Thanks for checking out my weekend project everyone!<p>All credit due to <a href="https://neuma.studio/" rel="nofollow">https://neuma.studio/</a> who blessed me taking their guide and wrapping it up into a small Python script.<p>My next step is to see what other devices I can run this on. Looking for the smallest device with USB host capabilities, Bluetooth, WIFI and Debian !
