Freezes on Clock.py late prompt.

[BeanWizard131]

Attempting to run with an original launchpad mini. Program starts but then freezes and says clock.py is running late on the tick speed. I've gotten the pad to do a sort of firework looking animation but no playing yet unfortunately. But there's a decent chance it's because I'm using the latest version of Raspbian and a port name got changed along the stream of updates.

Hi!

Would you be able to run mido-ports and copy-paste the output here?
(It's a small program that normally gets installed with the mido Python package.)

It should show the names of the devices, and there is a good chance that it will show us the name that needs to be put in the code to get the LaunchPad Mini correctly detected.

(I happen to have a LaunchPad Mini at home, but I'm currently on vacation so I can't check yet unfortunately!)

...Oh, scratch that, I just saw your screenshot on our other conversation:

OK, it looks like the LaunchPad isn't detected as a MIDI device 🤔

Could you also run lsusb to see if it was at least detected at all?

About the firework pattern: if it looks like circles (a bit like the waves when you drop a rock in a pond of water), I think it is the pattern made by the LaunchPad when it is powered on, but not connected through USB (or, at least, hasn't been "hooked" to the bus). I would try to connect it to another port; or maybe try with another cable. (This happened to me once because I had bought a very short cable to put the LaunchPad in a custom case along with the Pi; only to realize that the short cable that I had bought was defective: it brought power to the LaunchPad but didn't work with USB...)
