I tried switching back to the Akai (which I had gotten working before with the same basic code), and now it was hanging up, with Usb.getUsbTaskState() returning 0x12, 0xf, and 0x3e, switching between these randomly on resets.ĭoes anyone have any insight? Anyone have examples of usb-midi with the new library for this? I’m at my wits end trying to break through this, especially after 2 weeks of nothing.

About 10 minutes later, I reset the arduino and tried it again with the same code, and now I’m getting nothing. My final straw that has officially driven me insane was a moment where after days of searching usb specs, looking through the library, and looking for examples, I reverted to the basic example provided with this link and got the OP-1 talking. The three devices I’ve been testing are the Akai MPK mini keyboard, the Korg nanoPad, and the Teenage Engineering OP-1. I’ve been poking at this for a while now (2-3 weeks, everyday), and I keep getting sporadic results.
