Got AGML installed. It's a 208MB rar, 728MB decompressed. Installer includes 32- and 64-bit VST plus RTAS and AAX versions, plus a pdf showing the differences between the free and full versions (user documentation is online only). I only installed the 32-bit version, which was 701MB installed. Both a standalone executable and a VSTi plugin are included.
The installer asked me where I wanted to install it (I put it on my sample drive) but did not ask where to put the DLL, so after installation I dragged the dll into the cakewalk plugin folder and ran the scan.
I dropped it into an existing project with a finger-picked acoustic guitar and got instant gratification. First observation: it's more CPU-hungry than my other libraries. The project ran at about 69% on the first core before inserting AGML; after adding AGML it jumped to 83% and required bumping up the ASIO buffers to be able to play without dropouts.
Sound was quite good in solo, but I had to roll off a lot of low end to make it fit into the mix. This is normal and not really a bad thing, because you'll want that fat-bottom sound when featuring the instrument on its own.
AGM is not a Kontakt library. It comes with its own integrated player. That's a plus for those who don't own Kontakt. At AGM's price point ($169) it's more expensive than most Kontakt-based instruments such as Pettinhouse Acoustic Guitar at $99. It's competitive with Orange Tree Samples' product, which at $179 requires that you also have Kontakt and Vir2 Acoustic Legends ($200) that uses the free Kontakt player.
Bottom line after first impressions: if you don't currently have a nice acoustic guitar sample library, grab this freebie at once before they change their minds. If you already have a bunch of AG libraries, this won't add much to your collection (but the full product might).
