How can I create a tempo map for mixing drum loops to my previously recorded rhythm guitar tracks? My rhythm track includes tempo changes and tempo variations (with a good 'feel-factor'). The Beatmapper uses a single measure length for the entire song. I can drag the end of the measure selection to change the measure's length. However, changing the length will affect the entire song. Apparently Beatmapper is not the tool for what I'm trying to do? Isn't the first track Acid's master timing track or tempo track?

I could re-record the older (1998) rhythm tracks to a new drum loop as a guide track. However the feel of the old recording is good. Stylistically, live tracking is probably my preference but the loops should add an 'acid-jazz' feel to the acoustic folk/rock guitar parts.

Thanks,
Kleb

I found this post from SonicPCH in the "ACID 4 and OPT" thread.

"ACID's main time line is the master tempo map."

Could someone please elaborate for this newbie?

Thanks Iacobus,

The "Hit marker" may be just the solution! I'll let you know how it turns out!

Getting this error message at step 5: "The requested match would require a tempo outside of the allowed range."

I'm also confused! What's the difference between steps 4 & 6?? (set the cursor at measure 2, beat 1. Perform step 5. Then move the cursor to the beginning of the second measure...again?)

Joels solution reposted here:
1. Bring the song into ACID all by itself as a one-shot.
2. Set the cursor at the beginning of the first beat.
3. Press H to bring up a Hit marker at the first beat and to show the time ruler.
4. Set the cursor at measure 2, beat 1.
5. Right-click the Hit marker and choose "Adjust tempo to match marker to cursor"
6. Move the cursor to the beginning of the second measure (the fifth beat, if you're in 4/4 time), and press H again.
7. Move the cursor to measure 3, beat 1.
8. Right-click the Hit marker and choose "Adjust tempo..."
9. Repeat steps 6-8 until you're done with the song.
10. Render the song out to a new file, and you have an even-tempo'ed song.

Good questions. Sorry I wasn't entirely clear--the answer to your question about why you got that error message is that in order to match the cursor to the hit marker, the tempo would go outside of your limits (70bpm to 200bpm by default).

Please allow me to entirely repost the instructions (the previous ones weren't as instructional as I'd hoped--sorry, a bit tired):

1. Bring the song into ACID all by itself as a one-shot. (Make sure that the beginning beat of your file is somewhat close to measure 2, beat 1.)
1.5 Press F8 to turn off snapping.
2. Set the cursor at the beginning of the file's first beat.
3. Press H to bring up a Hit marker at the file's first beat and to show the time ruler.
4. Set the cursor at the ACID timeline's measure 2, beat 1 (this setting is just arbitrary, but should make sense in a bit (to alleviate the error message you mentioned, make sure that the beginning beat of your file is somewhat close to measure 2, beat 1).
5. Right-click the Hit marker and choose "Adjust tempo to match marker to cursor"
5.5 Press T to create a Tempo marker there.
6. Move the cursor to the beginning of the file's second measure (the fifth beat, if you're in 4/4 time), and press H again.
7. Move the cursor to the ACID Timeline's measure 3, beat 1.
8. Right-click the Hit marker and choose "Adjust tempo..."
8.5 Press T to create a Tempo marker there.
9. Repeat steps 6-8.5 until you're done with the song.
10. Render the song out to a new file, and you have an even-tempo'ed song.

Enjoy.

To add to what Joel said, you can adjust the project tempo range by going to Options>Preferences on the menu bar and clicking the "Editing" tab. You can adjust from 40 BPM to 300 BPM.

Awesome! That's exactly what I wanted! Tempo Markers were key.

A few notes or clarifications:

"...make sure that the beginning beat of your file is somewhat close to measure 2, beat 1" -- It took me a minute to realize that I need to begin my song near measure 2, beat 1.

"...Set the cursor at the ACID timeline's measure 2, beat 1" -- This would be the Acid Beat Ruler.

It's also handy to use F8 to toggle snapping On and Off. 'On' for selecting Beat Ruler measure markers, 'Off' for selecting the file's beat or transient peaks.

This is a great tool! Thanks guys.
