Kawai | K1r II


The Kawai K1II digital synthesizer offers 16-voice (max) poly- phonic output from Kawai's VM additive synthesis tone generator. The Kawai K1rII is the rack-mount version.


VM tone generator

The K1II built-in sound generator offers a selection of 256 basic waveforms using the two most advanced approaches to sound synthesis: 204 formed by the additive synthesis of the first 128 harmonics; 52 recorded with PCM sampling. You can freely mix up to four of these waveforms to produce an entirely new sound: a crisp digital sound, a rich analog sound, or any combination in between.

AM (Ring modulation)

The addition of ring modulation expands the K1II range to include overloaded sounds of the type that digital waves alone cannot reproduce.

Rich selection of tone patches

The K1II leaves the factory with 64 SINGLE patches and 32 MULTI patches already stored in its internal memory bank. The K1II's full editing capabilities and D08 memory cards (available as extra cost options) allow you to build up your own library of original sounds.

Built-in effects (REVERE/DELAY)

Sixteen built-in effects simulate the reverberations of a variety of spaces — concert hall to intimate studio - or add stereo or cross delays.

Separate drum section

This track, which offers a selection of 32 percussion instruments, is completely separate from the eight multi-timbre patches. This independent rhythm section may be assigned its own MIDI channel which is not affected by the OMNI ON mode.

Superb touch response

The K1 ll keyboard supports both velocity, the force with which you hit the key, and aftertouch, the pressure that you apply as you hold the key down.

Joystick for real-time control

The joystick provides real-time control over the balance between the four SOURCES of a SINGLE patch or between four section in a MULTI patch. During editing, it provides a rapid means of changing parameter values.

MuIti-tone patch LINKs

The K1II LINK function allows you to link up to eight tone patches -— SINGLE or MULTI, INTERNAL or EXTERNAL — from the 192 available and then step through the series during a performance simply by pressing the LINK switches.

MULTI patches

The K1II's MULTI patches go far beyond the DUAL or SPLIT functions of other synthesizers in that they allow you to assign up to eight different SINGLE patches to different ranges on the keyboard and divide the key velocity as well.

Variable multi~timbre operation

This function helps maximize the use of the K1II's 16-voice polyphonic capabilities by automatically redistributing unused capacity from one section to another.

Full MIDI implementation

Since each sound source can be assigned a different MIDI channel, each K1II MULTI patch can simultaneously serve as up to eight (or nine, using DRUM SECTION) different MIDI sound sources. For further flexibility, the K1" allows the musician to choose whether each sound source responds to notes received on the MIDI channel, those played on the keyboard, or both.

Interchangeability of tone data with K1, K1m, and K1r Since the K1II has interchangeability of tone data (SINGLE, MULTI patch) With those instruments of the K1, K1 m, and K1 r, the Klll can use the tone card for the K1, K1m, and K1r, or exchange the data among those instruments.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
