Help with dynamic split -> Add Stretch Markers

jzucker · 07-28-2020, 04:08 PM

Use case, I import a drum track which is recorded at a particular tempo but is slightly off. Ideally, I'd like to use the dynamic split -> Add stretch markers and then stretch markers->align to grid. Unfortunately, the dynamic split doesn't work right in that case because it puts stretch markers on 8ths notes when I'm just trying to align the 1/4 notes with the grid.

Is it possible to do this in reaper?

surely someone in this forum does this?

There are quite a few settings in Dynamic Split.

Are you happy with the Stretch Markers that it is placing? Are they all placed at quarter note positions?

Wrong!In Quantise Item Positions, is the setting in the option box 1/4? If it is set to 1/8, then it will quantise the stretch markers to their nearest eighth note, although that would need timing drift to the grid or seriously bad timing on behalf of the drummer.

Have you watched Kenny's video on drum quantising? There are two: Drum Editing - Stretch Markers and Drum Editing - without Stretch Markers. Watch these for a step-by-step guide on how to quantise using Dynamic Split and Quantise Item Positions.

Edit: This has reminded me -for Stretch Markers, use Stretch Markers in selected items / Snap to grid instead of Quantise Item Position. QIP is for items when you've used Dynamic Split to split your drums into slices to reposition rather than stretch. With Snap to Grid, of course, you need to check that the grid is only displaying quarter notes if you want to exclude eighth notes...

No, i'm not happy with where it puts the stretch markers. I have not watched the drum quantisizing videos. I watched another of his stretch marker videos. Thanks for the tip!

If you’re not happy with where Dynamic Split places the stretch markers, you need to adjust its detection threshold so it picks up the right transients. These will be detected using levels, though, so you might need to manually remove some if you can’t stop it picking up eighth note beats to start with.

Hey jzucker,

I would go for a more advanced solution (scripted one):

MK Slicer, an awesome script that let's you split or add stretch markers based on several conditions. You can, of course, also quantize the results:

Definitely also check the videos in the first post of the linked thread.

Looks amazing. where do I download it ? Do I download the whole gitlab repo? I'm not sure how to install/configure reaper to use it. Some details would be nice for noobs...

It's available via ReaPack, it's a package manager for REAPER addons (scripts, JSFX, themes, etc...).
Here's a tutorial on how to install it:

When you have it installed, enter "MK Slicer" in the search of ReaPack
and just install it. After that you will find it in your action list.
I would suggest to either create a shortcut for the script or add it to one of your toolbars. Hope that helps!
