Sometimes soft and smoky... sometimes eerie and disorienting...
The vibraphone provides constant modulation of its resonator tubes using motorized fans and bulbulators.
The resulting tone is the famous tremolo effect: shimmering, shaky, floating, flying... and you can come up with 27 more epithets yourself.

Soniccouture's Vibraphone features True Tremolo and 23 layers of velocity that bring metal to life.
Samples with 24 bit 96 kHz quality may please some people.
