The XO factory library includes one-shots from the Addictive Drums range, including Reel Machines. I just did a search for reel machines samples, there are 176 of them. You obviously don't want them all, since they're velocity multisampled. The rest seem to come from Samplephonics. Together they cover a very wide range.
License transfers allowed like all their other products: https://www.xlnaudio.com/support/i-want ... rs-allowedAre the expansions NFR, or does XLN allow license transfers for all their products?
I let XO scan my foley and many sample packs have a "percussion" folder with the most random stuff in it. If a sample sounds like a major categorization you'll likely find it in that region. So thwacking a large plastic container could be in kicks or toms. Metal hit could be in hihats or cymbals. Fortunately XO accepts a lot of formats including FLAC so it finds all sorts of stuff.Is XO good for evaluating what would usually be considered "non-musical" sounds that could substitute for (or be layered into) the standard drum sounds? What about components of drum sounds?
If it really can't categorize something, it tends to be in the bottom-most region. In my experience this includes short-enough loops, especially melodic and vocals. In fact, you have to lower the "druminess" range in the filter to display them.
As for drum creation tools, if it sounds like something that's where it'll be. Quick thumpy transients tend to be categorized with cowbells and congas. Kick bodies will be with kicks. HIgher pitched transients are placed among closed hihats. Best to use the filter to narrow down, e.g., "alchemy transient", or at the folder level if you added them individually (highly recommended, don't point it at the top level).
