That's not the only condition that triggers that bug, but it definitely is one.

Yes, you could do that, or use track volume automation, and make sure you maintain a constant level throughout the transitions.

Logic Pro for Mac 11 requires macOS Ventura 13.5 or later. I suppose that means you can run Logic Pro 11 on an Intel machine! 😃

I've added the requirements info to the OP.

It's apparently a free upgrade. Apparently, some features are Apple Silicon only, such as Stem Splitter for example, not sure if you'll still be able to install LP 11 on Intel or not.

Logic Pro for iPad 2 was announced! https://www.apple.com/newsroom/2024/05/logic-pro-takes-music-making-to-the-next-level-with-new-ai-features/ Logic Pro for iPad 2 is available on May 13 as a free update for existing users, and available on the App Store for $4.99 (U.S.) per month or $49 (U.S.) per year, with a one-month free trial for new users. Logic Pro for iPad 2 requires iPadOS 17.4 or later.

I've created a Logic Pro 11 thread:

Yes!! Let's use my official announcement for the Logic Pro 11 discussion:

Logic Pro 11 was announced today, it will be available on the App Store starting Monday, May 13. https://www.apple.com/logic-pro/ https://www.apple.com/newsroom/2024/05/logic-pro-takes-music-making-to-the-next-level-with-new-ai-features/ Logic Pro for Mac 11 is available as a free update for existing users and for $199.99 (U.S.) for new users on the Mac App Store. Logic Pro for Mac 11 requires macOS Ventura 13.5 or later. New features: With ChromaGlow, add the texture of tubes, tape, and other coveted analog hardware to bring more depth and color to your tracks: Stem Splitter: separate nearly any mixed audio recording into four distinct parts: Drums, Bass, Vocals, and Other instruments. Virtual Bass Player: Virtual Keyboard Player. Chord track: Chord Track adds and edits the chord progression of the song, so Keyboard Player follows along. Studio Bass instrument plug-in Studio Piano instrument plug-in

Make sure you never open more than 1 project at a time in Logic Pro. Opening 2 projects or more simultaneously is known to create unexpected behaviors that include mixing up channel strips between the projects.

The regions are indeed corrupted, and creating new regions with the "+" button next to a region creates corrupted regions as well. Converting to MIDI and back to Drummer does not help. You can Control + click to create new Drummer regions, and that works as expected.

Note: this is the kind of information you can learn from my book! 😉 https://www.logicprohelp.com/logic-pro-book/ Click the name of a cell to select it. Choose Logic Pro > Control Surfaces > Learn Assignment for "Live Loops Cell (Column #)". Hit a pad on your controller.

Can you reproduce the issue without the Little Radiator plug-in?

Save the project as a copy and as a folder, and in the copy, remove everything that's not necessary to reproduce the issue, and attach only the Logic project (not the audio files).
