Rumble K II Light is an emulation of an additive wavetable Kawai K1 digital synthesizer from 1985. This Rack Extension mimics the operation system and the naming conventions on a Kawai K1 and also contains all the default patches: 64 single instrument patches and 32 multi instrument patches.
Rumble K II Light is build as a patch or instrument browser. It is basically a rompler, but this version of the Rumble K series has some additions such as Sine, Super and Sub oscillators, a Wave Loop Shaper, an Amp Envelope section with ADSR controls, 7 effects devices and a Modulation Matrix.
The Rumble K series derives its name from the legendary guitar 101 hero and inventor of the power chord: Link Wray, who used to poke a pencil in an amplifier speaker to get a gritty, distorted sound.
