Midi quantising

I recorded a drum midi track without using a click or tempo track. As the drummer sped up a bit I need to link the performance to a tempo track and quantise his performance. How do I do this? It would take a really really long time to use the midi editor to move each individual note!

Maybe the following topic can help?..

If you follow those steps correctly, it will create a tempo map that matches the drummer exactly, then (once you are back in regular “Musical Mode”), you can straighten out the tempo, if necessary.
