Hello everyone,
 
I'm hoping my fellow "SONARians" can help point me in the right direction.  I am making a new recording and the tempo of my project is 120.  I have to record an arpeggio guitar part, but my finger picking leaves much to be desired in terms of speed - so I can only physically play the part successfully at about 90 instead of 120.  It's just me, so I can't rely on anyone else with better skills.  
 
My question is......How can I get my 90 arpeggio to fit perfectly into my 120 project??
 
I know I can use the stretch tool to "squish" it in, but there is no good way to perfect the timing using that method. 
 
Thanks

OK...I realize the REAL answer is that I need to become more proficient on the guitar, but NO ONE has any suggestions on how to do this??

If the project has any/enough MIDI tracks in it for you to reference while recording the new part or if you can record it to the metronome alone, you can just:
 
- Mute audio tracks
- Change the tempo (which will affect only MIDI and the metronome)
- Record the new part
- Enable Audiosnap with Clip Follows Project in autostretch mode on the new clip
- Change the tempo back to 120
- Bounce the 'stretched' (actually compressed in this case) clip with the appropriate offline rendering algorithm to get the best result.
 
 
If the project is all audio, or you need audio tracks for reference, you'll have to first enable clip follows project in autostretch mode on all audio tracks before changing the tempo. After reverting to the original tempo, the pre-existing clips should remain unaltered and not require bouncing. Nevertheless, in order to avoid damaging the existing project (Audiosnap can be tricky, and sometimes not 'undoable'), I would probably do all this with a copy of the project, and then import the new clip into the original project when satisfied with the result.
 
The amount of audio 'stretching' needed do to get to 120 from 90BPM is considerable, and it may be difficult to get a good-sounding result, but speeding up generally works better than slowing down.
 
 
 
 
 
 

Hey Thanks Brundlefly.  I'm not very familiar with Audiosnap.  Most of what I do is pretty straight forward and simple, so I have never REALLY dug into it.  But if you think that is my tool for making this work, then I guess I will start learning.  
 
Yes, it is a considerable amount, but I can actually record and render the arpeggio guitar part in a separate project all on it's own and then import it into my main project.
 
Thanks again for your help and if you should think of any other details, please let me know.
 

The important thing is to make sure Clip Follows Project is in the Auto stretch mode so that SONAR will make no attempt to snap transients to the timeline, but will just uniformly stretch audio when the tempo changes. This is the default mode, but to be sure:
 
- Select the audio clip(s)
- Hit A to bring up the Audiosnap "palette"
- Click the drop-down arrow to the right of Clip Follows Project
- Ensure it shows a check next to "Auto stretch"
- Click the Clip Follows Project button
- You should see no change in the the relationship of clip start/end times to the timeline now or when you change tempo.
- The Now time cursor speed will just decrease/increase to play the project slower or faster.
 
 

I really appreciate your help.  Thank you so much.  I will try it out tonight when I get home.
 
Thank You Brundlefly.

 
I've just tried this with a four bar long arpeggio guitar part, recorded to a  midi drum loop  in 80 Bpm, than trimmed the clip to exact 4 bars, than turned it in to a groove clip. When I turn up the Bpm now (in my case it was 90) the groove clip follows the tempo. But you will get some pretty heavy artifacts. Too much to keep it as a take, i.m.o.  As Brundlefly mentioned above, 20 Bpm difference (in your case) is a considerable amount for audio stretching.
At least this method is a quick way to find out if the part would work.
 
Good luck
Daniel

Record one note at a time.

Audacity has very simple tools to alter the tempo without altering pitch, so you could try exporting your mix to that to make a track you play/record  with, then use it to speed the recorded track back up afterwards. I can't say that I've ever actually done it, but it's a simple thing to try without having to get into audiosnap etc.
