Ok, it's been a couple of weeks since I asked for help, and I see that more than 50 people have viewed my request, but nobody has responded. I'm assuming that either all those people viewing think my question is too elementary and I'm unworthy of help, or they're newbies and have the same question. Probably both.
I've done some more work to answer my own question, but I still can't get SL to work in Ableton. Hopefully this will help any lurkers who have the same question. Any maybe it will help SL people improve the documentation so we don't have to ask here just to get SL working in Live.
Here's what I did:
I found the help .txt file "README_AudioUnit.txt. It says:
INSTALLATION-- Just copy the SooperLooperAU.component file to the
Library/Audio/Plug-Ins/Components/ folder beneath your home directory
or your system disk. If it doesn't show up in your plugin host, you
might need to log out then back in.
I found the .component file and moved it to that directory. Fired up Live and tried it. No luck.
Went to Live Preferences | File and turned on "Use Audio Units." Also did a Rescan Plug-Ins. No luck.
I opened up the Live manual to see what it said about AU installation.
Audio Units presets have an .aupreset extension and are stored in the following directory
according to their manufacturer’s name:
[Home]/Library/Audio/Presets/[Manufacturer Name]/[Plug-in Name]
Ok, so Live is looking for .aupreset files, and SL comes with a .component file and an .app file. I put both in the /Presets directory, and to be safe in about 3 other places under the Audio folder, including the Apple folder. No luck. Rescanned Plug-ins in Preferences. No luck. Exited Live and re-started. No luck.
When I say "no luck," what I'm doing is clicking on the Plug-in Device Browser and looking for anything that might be Sooper Looper. The Apple AU devices work. Aha! I'll see where the Apple devices are stored. Did a Spotlight search for "AUBandPass," the first Plug-in. Nothing. Did a search for the extension ".aupreset." Nothing. So now we have two mysteries--how to get SL to install, and where are the AU presets installed by Live on my computer. I dragged some the Apple AU devices into a track, and they are there and work.
Please, somebody who knows the answer give me some clues. Obviously I'm not lazy and I'm willing to dig in. But I've tried everything the manuals say to do, and can't install SL. I've heard some very good things about Sooper Looper and saw it in action. I really want to install it, because I love looping with my Echoplex, but now I'm migrating everything to Live. That's what a support forum like this is for, right?
I'm running Live 8.1.4 on a fairly recent Macbook. I've gotten everything else to work, though this is first time I've tried a plug-in.
