looking for uptempo swing / bop jazz drum loops

[azureblue]

short ones a measure or two long will do, but they need to work at 310 +BPM. For practice purpose, so free is good....

You should have little trouble coming up with your own here:

Monkey Machine - online drum machine

bpm goes to at least 500 if you're of that ilk. You can also do odd time sigs by editing the length of the pattern.
