AudioSnap: Is This Possible?

Yes and yes.

Record the guitar track. Use audiosnap to extract a tempo map as in this video.

Add ezdrummer and you're good to go.

Possibly, the tempo map is what any MIDI will follow. Any sync issues may well be a different matter.

Okay, I turned AudioSnap on for the acoustic guitar track and clicked Edit Clip Map. There's a slight delay at the beginning of the track before the guitar part actually starts.

Problem: I tried moving the 1:1 marker up to where the first beat of the guitar part is, but it won't stay there.

I don't know if this has anything to do with why the marker won't move, but AudioSnap put a transient in the 'silence' before the guitar part and this is where the 1:1 marker wants to stay. Each time I move it, it pops back there. I can't delete the transient because it's not user-created.

Anyone have any idea how to get around this so I can move the 1:1 marker to the first beat of the guitar part?

 Yeah, it does turn yellow.

I did come up with a solution, although I don't know if it was the proper way to do it. I just split the clip after that errant transient, then deleted that first segment. I bounced the clip and then I was able to line everything up.

Thanks ever so much for your help. I watched your video on editing clip maps "the easy way" a few times to get the whole process down. Now that the experiment has worked, I feel much more confident.
