midiclock.py not detecting beat packets

[maaraneasi]

Hey!

I am trying to use midiclock.py with my pair of xdj 1000's but I found that the script is not detecting the tempo for some reason.
If I use any of the monitor packages, these detect the master player and its current tempo just fine but not the midiclock.py. midiclock.py detects the players, it sends the initial bpm (I can see the connected midi device to receive the initial clock, but the tempo doesn't follow the actual tempo of the players.

Any idea or debugging steps for checking what is wrong?

Thanks for help!

midiclock was still using a callback that was removed from the internal API a long time ago. Unfortunately I forgot to remove the function to set that callback, otherwise I would have noticed that earlier. Can you try commit 832db37 and see if it solves the issue for you? This is not yet on the master branch as I'm currently working on restructuring the whole project.

Hey!
Thanks for getting back to me and checkking the issue!
The new commit works fine and sends the midi clock as expected. One issue I found is that pressing pause on the player crashes the script:

[flesniak]

Ah, division by zero. A classic.
This should be fixed in 02b7dcc, among lots of other things. Can you try if the overhauled version works for you? Sorry for the delay.
