There is a small group of us working to translate Kontakt only instruments to the free SFZ format. Join us! I look at the Kontakt instruments (click the wrench) 15 minutes at a time in Kontakt player and translate them into SFZ. Unfortunately I don’t have as much spare time as I would like.
Then upload the SFZ as: Original Instrument Name (SFZ version)
I just did Gentle Vibes by Jon Meyer. It should be on the site soon.
