How do you adjust the MIDI tempo?
 
I have these renditions of the same song that play at exactly the same tempo to the ear, but one person recorded their version at 160BPM and another at 80BPM.
In other words, the person who recorded their MIDI file at 160BPM was actually playing in half-time. So now the songs dont sync in Sonar or ACID because one is twice the speed of the other. It makes sense to want a different MIDI tempo when the tempo difference is a double or half.
 
Is there a way to change the version from 160 BPM to 80 bpm or vice versa ? Being able to slow a MIDI loop by half or speed it up 2x comes in handy sometimes.

- Open the 160BPM file as a new project and set the Now time at 3:01:000
- Hit Shift+M to open Set Measure/Beat At Now, and enter Measure 2, Beat 1, and OK.
- SONAR will change the tempo to 80 without altering the absolute timing of the playback (start times and durations will be adjusted accordingly).
- Import the 80 BPM clip into that project (or export and bring them both into another 80 BPM project), and they should play together.
