Logic RAM issue

I am not sure if this is normal for Logic Pro X but, right now, I have Logic open but not currently playing or actually using it

The project that is open is a 1 minute long, 4 track project containing 2 MIDI tracks and 2 audio tracks (from Apple Loops (1 of the audio tracks is merely 1 beat long)) --There is automation on each track

Project:


Project Information (however, Reorganize Memory was grayed out and did nothing when I pressed it):




Here is what I have tried so far, with mixed results:

Closing logic, then reopening it: It brought the RAM usage down to 2.3GB

Checked the mixer window to make sure there weren't any hidden channels with tons of plugins loaded: Nothing hidden

Closed the original project and opened a completely blank project: This brought it down to 1.8GB RAM -- When I then reopened the original project, it showed 1.4GB RAM (Why would a completely empty project show more RAM usage than the original project?)

Disconnected the audio interface prior to opening Logic: Tried this and when I reopened the project, the RAM was at 2.2GB

I just checked the RAM usage and it is back up to 3.1GB, despite my having changed nothing in the past hour

Any advice you might have would be appreciated.

My system:
• Logic Pro X 10.4.8
• OS X Catalina 10.15.3
• iMac (late 2015 27" Retina)
• 4 GHz Quad-Core Intel Core i7
• 32GB RAM
• Apogee Element 24

The issue was that Logic was taking up a large amount of RAM despite no tracks playing - it was merely open in the background
oh I see.

I couldn't find in your original post how much ram it was using so I wasn't sure how much is a large amount.

In my experience logic seems to use the same amount of ram whether the project is playing or just open.

I believe it keeps everything it needs for the project loaded in to ram so that it will play without issue.

I was just playing around to see what sort of results I had.

Most of my projects seem to use anywhere from 2-3.5 GB of ram.

I also don't think it releases ram when you close a project.

I have it open right now with no project open and it it using 1.89 GB of ram.

I don't think any of these are large amounts, especially since your machine has 32 GB of ram at its disposal.

Did you manage to resolve the issue?

Yeah it seemed to resolve all on its own

Now if I could only change my writing habits so that I actually finish a song rather then getting a new idea and writing the first 1 minute of a new song each time I open an old project -- right now I have 23 projects started with anywhere from the first 30 to 90 seconds complete

Maybe I can combine all 23 into one magnum opus? :)

ha!

I have this problem a lot.

My writing partner has the opposite problem. He will keep adding more and more parts to a song to the point that I have to convince him to break them up in to separate songs.
