Has Support for Custom Icons Been Removed in LogicPro X?

Yeah, I can't figure out where they put them either. I'm choosing to be encouraged that they copied the icons to the Audio Music Apps folder, but so far I see no way to use my many icons.

I've been thinking of trying this, but I can't figure out ow to make a multilayer tiff on a Mac. You can look at the layers of the factory icons in Preview, but making one of my own is eluding me so far. Photoshop and Pixelmator can't create multilayer tiffs. Presumably Apple used a Mac to make the factory ones, but how?

I'm not saying I endorse messing with LogicPro X's app package, but I've at least figured out how to make a multi-page TIFF (it's not really called a "multi-layer TIFF," apparently).

You need a photo app like Pixelmator or Photoshop variant, and Preview. Amazing little app, that one. You'll need to know how to use your photo app.

Here's what you do.

You open the image you want to use as an icon in your photo app and size it so it's 512 x 512 pixels at a resolution of 72. Make everything around the actual content transparent, flatten the image, and save it as a TIFF, preserving its transparency. Go back into the Image Size dialog, and change the image's size to 256 x 256, keeping the resolution at 72. Save this version as a second TIFF. Repeat three more times, at 128 x 128, 64 x 64, and 32 x 32 pixels, all at a resolution of 72.

Launch Preview and open one of the TIFFs. Open the Thumbnails pane. Open one of the other TIFFs and show its Thumbnail pane. Drag the thumbnail of the second TIFF ON TOP of the first TIFF's thumbnail, not underneath or above it. Repeat with all of the TIFFs until all five are visible in the first TIFF's Thumbnail pane. Drag them around until they go from smallest on top to largest on the bottom.

Export the result as a new TIFF; Preview will make it a multi-page TIFF for you. Once you've saved it, you can re-open it in Preview to verify that all the sizes are there.

Well, that's one part of the custom icon nightmare riddle solved anyway.

Again, I'm not sure I'm gonna mess with my own LogicPro X install, and this should definitely not be taken as a suggestion that anyone else should.

Let me add that you should use LZW compression when you save your TIFF from Preview.

Let me also say I tried the steps linked to above for actually installing the icons and editing the plost file, and they didn't work for me.

Okay, after hours of fiddling, I got this working and I now have custom icons. I'm not sure why I finally succeeded, though I do think two things were/may have been deciding factors:

1. When Preview exported my TIFFs, it set the permissions for Staff to Read-Only. They need to be set to Read-Write.

2. I suspect that TextEdit mucked up my edited plist file, causing dialogs in LP X to be green (!) at launch, and then the app to crash. When I switched my plist editor to TextWrangler, which is freeware, the green issue went away. Coincidence? Dunno.

Hopefully I haven't de-stabilized LP X. Not for the faint of heart.
