I just now downloaded Kontakt 5 Player cuz for some reason I thought I read where it could handle these 2 file formats, SF2, and SFZ.  Am I living in CO where folks smoke a lot, or what?  If it DOES support these formats, how do I convert them to NKI.  I've looked all over the screen and canNOT find the Activate button. 
 
For that matter, I also downloaded the Sennheiser DrumMic'a that's specifically for Kontakt 5.  I didn't run the little Kontakt installers in it, cuz I thought that K5 would automatically see them.  NOT! So do I have to install that extra 9Gigs onto my SSD C:Drive that only has 120Gig total?
 
Yea, I know.  Cakewalk has SF2+ (whatever)...I downloaded both versions, and installed both, but can't find hide, or hair of it ANYWHERE on my PC.  It doesn't have a .dll like most VST's.  And of course, the serial is no good after 48 hrs.  I e-mailed Sonar support immediately.  That was Monday night.  Ask me if I've heard anything from them.
 
HEP ME!

Kontakt Player limited - I think it will play SFZ and SF2 but only in demo mode, ie it will time out after 15 mins and there is limited functionality. I use full (paid for)Kontakt to play SFZ and SF2 but dont usually bother to convert to NKI. It is possible however on the full version.
 
If you are looking for a free solution for SFZ and SF2 files you can do a lot worse that TX16Wx -
 
 

• Reads multiple sample and bank formats
• WAV/AIFF/AIFC
• SoundFont 2
• SFZ Files
• Ogg Vorbis
• FLAC
• Typhoon compressed AIF files
• Original Yamaha OS Wave files

Don't forget the excellent free sforzando player from plogue - it's the same engine used by Garratan.

That TX16Wx (what a terrible name!) looks mighty impressive - for free (!). And the paid version's only 29 euros. You get a lot of Kontakt-like features (e.g. keyswitches and round-robins), including at least one feature that Kontakt doesn't have: it can actually sample.
 
Downside is there isn't the wealth of commercial libraries that Kontakt has, so it's less of a plug-and-play solution. And, of course, you won't have Kontakt's deep scripting language. However, there are lots of sfz collections out there for free or cheap, and even though you don't get scripting, the sfz format has many of the capabilities you'd normally write a script for built in.
 
If I wasn't so deeply committed to and heavily invested in Kontakt I'd be all over this one. Too bad it didn't exist back when I first bought into the Kontakt paradigm.
