I need to get back to this page to watch the video about creating stems…

Stems In Music Production — Everything You Need To Know | Production Expert

Stems are submixes of a larger mix, that when played together at equal volume will exactly recreate the full mix.

Typically, this will mean dividing larger ensembles, whether recorded naturally or artificially, into smaller subsections. An orchestral mix might be stemmed into strings, brass, woodwind and percussion, or a rock band into drums, guitars, keys and vocals. Crucially, stems are groups of elements that make up the final mix, not the individual elements themselves.

The main thing to bear in mind is that you’ll need to duplicate some resources here. On a regular mix you only need one of every effect, say reverb and one delay. But when stemming you need one of these for every stem, routed to the relevant stem bus. Otherwise, you’d have the effects of all the different stems on one stem, and the point is to separate things. So if you’re creating four stems you’ll need four sets of effects busses. You can imagine how quickly this will start to take up system resources if you’re printing a lot of stems, and especially if you’re working in 5.1 or 7.1

Simple enough to create effects tracks for each stem. Just have to remember to do it when mixing the project.

In the Logic Pro X world, if you’re using summing stacks, you might simply want to insert the effects on the stack and use the mix control knob to adjust the levels appropriately. If the recipient of the stems insists on separate effects tracks per stem, well, OK…that’s just not that hard to do.

A good practice would be to create a track for the effects bus (need to do this anyway if you want to bounce the stems) and place it right along with the summing stack in the arrange area.

  Export All Tracks as Audio Files…    ⇧⌘E

Export all audio, software instrument, and Drummer tracks as audio files. This command can be used to export effects buses as well — make sure the effects channel has a track created for it.

Fast and efficient way to create “stems” for sharing with others.

Export tracks as audio files in Logic Pro — Apple Support

You can export one or more selected tracks as audio files, or export all tracks (all audio, software instrument, and Drummer tracks) in a project as audio files—one file per track. When you export tracks as audio files, you can specify the naming of the audio files using filename elements.
