Figured I would reply to this here, rather than the sale thread.
Longer samples are no issue. I have a directory of field recordings that are 30-40 minutes long. Aside from taking a moment to draw the wave, it all works great.

In addition to managing regular sample libraries: If anyone finds themselves with folders upon folders of old projects that never went anywhere, just point Sononym at the highest directory level and you’ve got instant access to all the source audio and snippets from previous projects. Super easy to listen to and find projects to come back to, or to use that audio elsewhere.
