Boulder Sounds has released Mini Sax - a free sample library that captures the sound of Juan Del Rio's Mini Sax.
The sound of the mini sax has been described as somewhat of a cross between the clarinet and the sax.
It is in the key of Bb and is an octave in range. For this sample set, the range has been expanded to 2 octaves, going from G2 to G4, using polyphonation from Redmatica Keymap.
Bo Clausen has also contributed his usual wonderful KSP Kontakt scripting, which is explained in the .pdf manual.
