Delete Similar Regions/Events

_Similar_ needs definition.

When working with MIDI events (notes) the command will delete all of the events that have the same note value. I guess _similar_ means that velocity and duration are unimportant.

The ‘Delete but Keep Similar Regions/Events’ is a simple way to isolate all of a particular drum hit, like a kick drum. Select a note, use the command, all you have left are the kick drum hits.

I still haven’t been able to locate a definition of what _similar_ events or regions are. My best guess, formed by playing with regions and selection commands, is that all MIDI regions are similar. All audio regions are similar. MIDI regions are not similar to audio regions.

  Set Selected Track(s) or Channel Strip(s) to Automation Read

This is the only specific ‘set’ command for automation modes. All the other commands appear to be toggles, including the ‘Toggle … Automation Off/Read’.

I think I have learned enough about Logic to start _not_ using Logic and start using my control surfaces.

Choose automation modes in Logic Pro — Apple Support

Read: Plays back all automation that exists on the track. If volume data exists, for example, the Volume fader moves during playback, following the prerecorded automation on the track. You can’t change the value of the chosen automation parameter by moving controls when in Read mode. However, you can record region-based information directly into a MIDI region in Read mode.

There are a variety of commands available for working with automation. I have an Apple keyboard sitting at the bottom of my X-Touch. I should mark these commands, or get very familiar, so I can start to automate my mixes simply while listening. This assumes I am mixing _stems_ or subgroups.

  Set Nudge Value to 10 Ticks

Adjust the nudge value to move 10 ticks at a time. A tick is a measurement of MIDI resolution. There are 960 ticks in a beat. A one second “beat” has 960 ticks of 1.04 milliseconds. A 10 tick movement would be approximately 1/100th of a second — .01 seconds.

Move regions in the Logic Pro Tracks area — Apple Support

When you move a region, it snaps to the nearest position on the Tracks area grid, using the current Snap value. You can override the grid by holding down Control while dragging regions to move them in steps of one division, or by holding down both Control and Shift while dragging to move them by single ticks or samples (depending on the zoom setting).
