Kawai K4 Digital Multi Spectrum Synthesizer

   (0 reviews)

This revolutionary new synthesizer uses 16-bit sampled and synthesized waveforms for optimum sound quality. The friendly user-interface and parameter structure of the Kawai K series has been retained, and new functions and features added to increase the K4/K4r is music making power.

The K4 is a touch-sensitive synthesizer equipped with a DMS (Digital Multi Spectrum) tone generator capable of up to 16 notes of polyphony when set at two Sources per tone in a 19 inch, 2U rack-mount module.

256 high quality internal waveforms The K4r has 96 DC (Digital Cyclic) waveforms composed of as many as 128 harmonics, and a total of 160 PCM waveforms, for a total of 256 waveforms. Because the K4's internal waveforms are reproduced using 16-bit quantization, noise and distortion are virtually inaudible.

DRUM Section The K4 has its own DRUM Section which can be controlled independently of SINGLE Patches or the eight Sections of a MULTI Patch. The 61 keys from C1-C6 on the keyboard may be assigned freely to produce these tones.

Realistic touch response The K4 has the feeling of an acoustic piano keyboard, a feature which has made the Kawai K series so popular. In addition, Velocity, Aftertouch, Release Velocity and Keyboard Scaling features allow the expression of the most minute touch on the keyboard.

MULTI PLAY capability Eight SINGLE tones may be reproduced by the DMS tone generator, freely combining the Layer, Velocity Switch and Split functions, enabling far more beautiful layered and split sounds than have ever been possible before.

Variable Multi-Timbral capability In the MULTI PLAY mode, each tone may be set to a specific MIDI channel, allowing the K4 to function as though it were eight MIDI tone generators (or nine with the DRUM Section). The Variable Multi-Timbral function also allows the voices of each Section to be played simultaneously.
