Hi Nick,
What you haven’t done is give any details about the equipment you’re using to input the music. Neither do you say whether it’s MIDI or audio you’re trying to record.
But, assuming it’s MIDI, are you using a MIDI to USB adaptor between your keyboard and the computer? The reason I ask is because if you’re using a cheap adaptor it may well be that this is causing the problem. There are more reported faults with low cost MIDI/USB adaptors than almost any other problems. They frequently have internal timing problems.It’s usually necesssary to buy a more expensive one from a known quality supplier.
