I'm missing something, somewhere. I've looked at the manual and youtubed. (I have the Reaper licensed version and it's up to date.)

In Reaper, I want to change an existing wav file track from its current 163bpm to 170bpm. I've tried just reseting the Project Settings in Project BPM (as a test) test 50.000 and 200.000, Timebase for items/env/markers to Time, and the next Timebase for tempo/time sig envelope to Time. (In case this helps - Proj start time: 0:00.000, Set 0.00 to edit cursor, and Project start measure: 1. Playback resample mode: Medium).

All the instructions (manual/youtube) seem very simple, either changing the proj bpm to whatever, 50bpm for example, or inserting a Tempo/Time Signature Marker. But, I don't get results. The playback tempo is still 163bpm, and song play length is unchanged.

Any suggestions?

Thank you.

P.S. I am aware that the pitch setting needs to be set to not change the track key.

Andy,

Try the following.

1. Turn on the grid and activate 'Snap to grid'. (The shortcut ALT+G will do this.)

2. Drag the right end of the wav track until it snaps to the nearest beat. (Let's say it's beat 1 for reference purposes.)

3. Change Reaper's tempo to 170.

4. Now hold down CTRL+ALT and move the cursor around the right end of the wav. The cursor will change to a hand. When that happens, grab the right end of the track and drag it to the left (since you've made the tempo faster) until it snaps to the new beat 1 in the same bar number as before.

5. Lastly, in the 'Project settings' make sure that the 'Default pitch shift mode' is set to 'elastique 3.1.4 Pro'. (I find this a good stretching/shrinking engine.)

That should do the job for you.

Regards,
Noel

EXCELLENT!!! That did it. (And those a completely different instructions than I found anywhere.)

You ARE a Reaper expert!

Thanks, Noel!

Hey, Noel. For vocals using the 3.1.4 Pro Algorithm, how many ms would you set the Attack time? Like my vocals, not Beyoncé. Old, beaten-up, fossil guy vocals. A range would be helpful. Thanks.

Andy,

For manually tuning vocals, I set Reatune to the following...

• Attack time = 50 - 80 ms (I mostly use 50)
• Stereo correction = off (since I only record mono vocals)
• Elastique 3.1.4 Solo -- this definitely works better with vocals than Pro
• Parameter = Monophonic

Hope this helps,
Noel

Excellent, Noel. I had nowhere to start. I could use 2000 and I just needed those range numbers. Thank you.
