So I'm charting a song.
Got the BPM set to what I'm 99% sure the BPM is.
I preview the chart in Reaper, all checks out. Looks mighty sweet.
Send it to my 360. It starts off fine, then will get out of sync about 5 seconds in where I have to be hitting the notes very early and then another 5 seconds and the song will be back in sync and 5 seconds later, out of sync again.
I'm not really musically inclined so I'm having a hard time figuring out why it's fluctuating like this.
