I"ve made a humble toy glockenspiel library for myself. It came out rather well so I’ve made a decisions to give it away.
Toy Glockenspiel is a free NI Kontakt sample instrument that you can use in every manner you’d like, including commercial use. The one exception would be to sell it.
Instrument includes three articulations:
Hard (played with standard mallets)
Soft (played with mallets fitted with some fabric, this is the one you hear in demo)
Felt (played with drum sticks fitted with felt, great for strange percussive stuff)
Every articulation has 3 round robins.
