I made a midi in cubase and exported it, when i put the midi back in cubase it plays as it's supposed to, but when i import to utau and export the vocals it's slightly slower, after a little experimenting i found that i need to export it at 94.7bpm (instead of 94) to match the original midi, is this an issue with how i use utau or should i look into experimenting with the midi and cubase?
