Muletone Audio had released Grand Glass Marimba 2 for Kontakt 5.8+.
Muletone Audio says:
In Brazil, the glass marimba was popularized by Brazilian instrumental group Uakti. Its members have built hundreds of percussion instruments, among them the glass marimba to a greater extent.
In the new session, six types of sticks were used, diversifying the textures and tones of the instrument. The library also explores motifs and grooves, including MIDIs.
Price: $24.99.
The Full version of Kontakt 5.8 or above is required (Not for Kontakt Player).
