Wavelore has released an updated version of Slide Whistle, a virtual sampled whistle instrument previously released in GVI/GS3 format.
This instrument, (~30 megabytes zipped), uses extensive formant-corrected portamento scripting with 8-way round robin staccato samples, expression filters, and other controls to allow you unsurpassed expressive capabilities in a small, free instrument.
It also comes with a 5-page manual in .pdf format. Check it out!
Slide Whistle is now available as a free download for Kontakt 2 and higher and GVI/GS3.
