Any way to have a MIDI region on one track be a master to a MIDI region on another track?

[bhuether]

This would be sooooo useful.  I often have some melody on a given track. Then I double that melody on other tracks.  Depending on that melody I often then have a counter melody on other tracks as accompaniment.  It is so time consuming to change my main melody and countermelody, and then go through all other tracks to propagate the changes.

That is why I was wondering, is there a way to set up master - slave regions?

If not, I think implementing that would be such a major feature, that Logic would have to have a new major release. Like Logic 11.

You can create aliases of MIDI regions (Shift-Option-drag a region) however then the notes in the aliases are exactly the same as the ones in the original.

Ok, I see it stays on same track.  Would be so cool to have master-slave relationships between regions on separate tracks.

That is really great! Would be cool if Logic in some future release gave settings for how that works. Like alias the notes, but not automation, etc.

Aliases have been part of Logic since the first version IIRC

Best way to do this would be to have separate regions, one containing only the note events (and possibly MIDI controller messages) and one containing only the region automation (would be best to keep them on separate tracks using the same channel strip). You could then alias only the region containing the note events.

Ok, that sounds great. So I take it I can have overlapping MIDI regions on one track, or do you suggest one track with note data, then track below it with automation?

Been using Logic for a couple years. Starting to like its approach.

Both approaches work (overlapping regions, or having them on separate tracks which use the same channel strip). I suggest the latter for better visibility though.

Great! You're welcome! 😀

As a complement to the above (in Logic X v.10.7.4):

 

You can create an alias for a MIDI region or a folder. An alias is a reference to a region, and looks similar to a normal region in the Tracks area. If you alter the original region, all aliases of the region are similarly altered.

Aliases can be useful when you want to repeat a phrase or riff in different parts of an arrangement. If you make changes to the original region after creating aliases from it, the changes apply to all its aliases throughout the project. If you want to edit one of the aliases without changing the others, you can turn that alias into an independent region (a region copy) and edit it independently.

Aliases do have some differences from their “parent” region: you can give each alias its own name, and edit region parameters for each alias independently.

Alias names appear in italics to distinguish them from normal regions. If you name an alias, its parent region name is shown below the alias name (provided that the zoom level is adequate).

Any changes made to the parent region name appear on all its aliases.

Create an alias

In Logic Pro, do one of the following:

• Option-Shift-drag the region to the position where you want the alias to start.

• Select the track you want to create the alias on, position the playhead, select the region you want to create an alias from, then choose Functions > Region Alias > Make Alias (or use the Make Alias key command).

  You can also use the Repeat Regions command.

If several regions are selected, their relative time and track positions are retained. The selected track is the destination track for the first region along the Tracks area.

Reassign an alias

You can assign a new original region to an existing alias. This is exceptionally handy for arranging tasks where the structure is right, but the specific part is wrong. You can copy a region to a new track, create an alias, mute the existing region, and click Play, or use the far simpler method below:

1. In Logic Pro, select both the alias and the intended new original region.

2. Choose Functions > Region Alias > Re-Assign Alias (or use the Reassign Alias key command).

Search for an original region or alias

If you forget where the original or source region is for a certain alias, you can search for it. In Logic Pro, do one of the following:

• Select the alias, then choose MIDI > Alias > Select Original (or use the Find Original of Alias key command).

• Choose Functions > Region Alias > Select Aliases of Region.

Convert aliases from deleted source regions

If you delete the original or source region used by one or more aliases, a dialog appears, asking whether to convert the aliases to independent MIDI regions or to keep the aliases. In Logic Pro, do one of the following:

• To cancel the procedure: Click Cancel.

• To change all alias MIDI regions into real copies: Click Convert.

• To delete the parent region, and retain all (orphaned) alias regions: Click Keep. Although such orphan aliases serve no useful purpose, Logic Pro doesn’t automatically delete them, in case you decide to reassign them to new originals at a later stage.

Select and delete all orphan aliases

If your project file contains unneeded aliases, you can quickly tidy up by selecting and deleting all orphan aliases.

1. In Logic Pro, choose Functions > Region Alias > Select Orphan Aliases (or use the corresponding key command).

2. Choose Functions > Region Alias > Delete Orphan Aliases (or use the corresponding key command).

Convert an alias to a normal region

You can create a real region from an alias; its contents are identical to those of the original region referenced by the alias, but its playback parameters are those of the alias. After it’s been converted to a real region, you can edit it (or the original parent region), without affecting the new real region.

You can also double-click an alias to open a dialog that asks whether you want to create and edit a real copy, or edit the original.

If you double-click an alias to edit it, Logic Pro assumes that you either want to edit the original, or turn the alias into a real region. You are asked whether you want to create and edit a real copy, or to edit the original.

• In Logic Pro, choose Functions > Region Alias > Convert to Region Copy from the Tracks area menu bar (or use the Convert Alias to a Region Copy key command).
