Many of the samples are quite short so these likely should be considered toys rather than production ready instruments. Oddly there are several professional Gamelan instruments that sound excellent, including one from Native Instruments themselves (go there for great info on the Gamelan), if you really get serious about digital Gamelan playing. There is also The Virtual Javanese Gamelan and a handheld Gamelan. Who knew the world would become Gamelan obsessed.
Individual Gamelan Instruments
Jegogan - Calung
The Metallophones - Kontakt 5
This contains these instruments remapped to fit in one instrument.
Jegogan: C3-A3 has been mapped to C1-A1 (down 2 octaves)
Calung: C4-A4 has been mapped to C2-A2 (down 2 octaves)
Premade Gangsa: D3-C5 mapped to D2-C4 (down one octave)
Hi Gangsa has not been remapped D5 and above (no change)
The Metallotoy - Kontakt 5
Somewhat like a Xylophone every key on the keyboard (well C2-F7) has a (correctly pitched) note as I've stretched the Metallophones. This is not realistic, but it is fun.
And more Gamelan fun!
This is a weird but fun sound. From a Gamelan with the samples dropped in the closest notes (most are pretty close) and then stretched to include every note in a two octave range. It comes from The Museum Nusantara in Delft, the Netherlands, 100 years old Javanese gamelan, Kyahi Paridjata.
