I have a track for a song a fiend and I wrote together but he is now the other end of the country so we are dealing remotely. The track is a key board track of piano and what i think is strings added as an aftertouch on the keyboard. Its not recorded to a clock track. What I'd like to do is get the chords, standardise the timing and replae the aftertoch strings with someting nicer from RTs. Then add a light percussion track and finally sing in a new vocal..

ACW and stems splitting sounds ideal. Shoud I do it in RB and BIAB - I always record in RB as Ican add several traks of harmony easily on separate tracks.

I have a freebie version of melodyne but idon't think its polyphonic and woudn't deal with a piano track bu there is one short dud note in the piano part i'd lke to get rid of. Any sugestions?
