My pal is coming in next week to do some acoustic stuff, now I know from previous work that his timing can be a bit off and I will be looking to pull some bits back into sync...how would you guys do this?
I did something like that manually by cutting, moving and fading.
Now, with Reaper, i can create "transient guide markers" and move them to "proper" position if needed.
It is kind stretching. Works really well. Hope you can find something similar in Studio One.
Divide song into major parts and let him record multiple takes into each part. Then do comping like u would with vocals. Some parts always repeat anyway. Just dont fidle with preamp gain in between takes and make sure your friend doesnt dance around with guitar in front of mike too much so u keep consistent tone accross different takes.
Alternatively ask him to practice it well before recording.
U can do occasional punch in. U can also manualy shift notes around in Reaper, thou it depends on whats recorded it may sound odd...
