Hey there

Yesterday I recorded midi drums to a click track for a song into my iPhone using an IK Multimedia iRig Midi.


I had the click track playing from my iPod (that I had recorded as an mp3 at 148pm) and I recorded the drum beat for the whole song at 148bpm into my iPhone using thr iRig Midi Recorder app.


I exported the file from my iPhone to my Mac.

When I play the file through QuickTime it plays fine at 148bpm OK, but when I import it into a new Garageband song (That Ive set the bpm to 148bpm) it actually plays back the midi drum beat at (approx) 183bpm.


If I import the midi file into iTunes, iTunes plays it at 148bpm, and even if I convert it to an mp3 using iTunes, iTunes STILL plays it at 148bpm.


But, like I said when I import the original midi file into Garageband it plays faster at (approx) 183bpm.


Any suggestions on whats going on here, because something isn't right.

    I assume you have checked, if your GarageBand project is set to 143 bpm?


    But even with the correct setting of the project the song may play faster, if you have changed the Master Tempo automation curve of the Master Track. Have you checked that too? I noticed that sometimes a midi file will change automation curves on the tracks on import.


    If you add an automation to the Master Track, the master tempo will show the tempo for the measure where the cursor currently is, so the part of the song with the click track may play at a different tempo.
