Thanks. Yes, the harp is me...stumbling along.
About the timing, the acoustic guitar riff is definitely off beat, sometimes....it's a weird, unusual but really cool timing, that, when coupled with a steady always on the beat riff that the bass plays, will sound off beat...because it is. I guess the only way to see if I'm right is if I recorded a bass track totally in synch with the riff to see if it would work, which, I might be able to do...
I don't know how to use audio transients to check the timings...Cheers!
