It is really frustrating that when you record a long sample and then want to listen back to a specific part of the song you have to play it back from the beginning, this is most annoying when recording guitar music and then trying to program drums for it. It was so annoying I actually gave up making a song over it.
You could fix this by adding a vertical sample player that you can drag samples onto rather than having to trigger them by playing the song back from the beginning again.
