Ral Ending

Yes :) Just go into the tempo map and draw the line in. This is the easiest way by far. You may want to tweak the line more precisely if you've already got it in your head.

Thanks both very much I'll draw and then probably have to change the feel (I have a 20 piece choir coming in the studio and they love ral endings)!!!!Arghhhhhh!

Yes you might want to bring the leader in and record  him singing the ending sans accompaniment by inserting  CC7 :0 in your midi file at the beginning of the ending and since they have undoubtedly rehearsed the piece and he probably "knows" how the feel of the ending goes.  Put your CC7 back to where it was or should be and then you will have a sense of where to insert your tempo changes in your midi file by matching your midi file to his vocal.   Then mute or delete his vocal. 
Since rall. and rit. are usually  "a piacere"   doing it that way should allow them to perform it and have it still sound "at pleasure" when you record the full chorus with the accompaniment.  I think. 
Or, you could do the mute thing CC7 :0 at the beginning of the ending and do your midi tempo matching sans chorus post recording the audio.  Probably expedite things that way since often the leader may not be available prior to the session. 

 

Thanks Tomas that will probably be the best option as you say It should help the feel to be more natural especially after editing.cc7=o in ready.
Thanks everyone Great to know there is great experience here on the forums.
