We primarily develop our products for the Native Instruments Kontakt
open-format platform, so you'll need the full retail version of Kontakt
to use many Soundiron instrument presets. However, we do offer a growing line of
specialized "Powered By Kontakt Player" libraries that can be used in
the free Kontakt Player. If you see "Player Edition" in the product
name, you can use it in the both the free Kontakt Player and the full
version of Kontakt. See our Kontakt Player section for compatible libraries: http://soundiron.com/collections/kontakt-player-edition-collection
And of course, you'll need a VST, AU, RTAS or AAX compatible host
sequencer, such as Reaper, Cubase, Sonar, Reaper, Logic, Acid, Presonus
One, FL Studio, Ableton Live, or Protools. Kontakt runs as a virtual
instrument plugin engine in most major host sequencers. Our libraries
are loaded as instruments into Kontakt.
We do offer a few of our libraries in other formats, such as
Propellerhead Reason ReFills, universal SFZ for the free Plogue
Sforzando Player and more. Just look for information on each product's
page about the system requirements and formats supported by each one.
