The most in depth collection is probably Eduardo Tarilonte’s Accordions 2 by Bigfish Audio but it is expensive - about $200. It is my all time favorite go-to when I want something more unusual sounding and at $29 hard to beat.

I have a few other products from other companies - like Boulder Sounds - which have some rather eclectic choices, but one of my all time favorites is Little Pump Reeds by Soundiron. I also have a Korg bundle with Triton and Triton Extreme as well as my still in daily use Korg Triton Rack and all of these have some great instruments in this category.

As others have commented, Sample Tank has several free-reed aerophone type instruments available.
