First off, can I ask if there are actually any instrumentalists/singers/rappers on here? I haven't really seen any (a few MCs maybe), but that's not quite the same kinda thing. If there are, I could do with some tips: Despite a fair few years of playing solo, plus a fair few group performances, I try to record some stuff playing along to a metronome on headphones and it's still a little bit out of time when I add a programmed drumbeat. I can't play the drumbeat whilst playing cause my piano is in a different place to my PC, and anyway I think it wouldn't help cause I'm already using a metronome. Is this me, or is combining live and recorded material just really unforgiving on otherwise unnoticeable slip-ups. Does anyone have any tips on preventing this from happening? Have I just got to record everything a dozen times to get it perfect? How do the pros do it?
