I'm working on recording with some musicians that didn't do very well playing with a metronome. Now i'm editing their tracks and I keep struggling telling the diffirence between slightly rushed and slightly dragged notes and spend too much time just trying to place the notes right eith trial and error (waveforms don't always help since the true note impact doesn't match with the start of a waveform). Is there a place I can practice distinguishing between that kind of rushing and dragging?
