In 1997 a rack-module version of the K5000 was released. The rack version shipped with Kawai's more stable OS 3.0 software. The latest is 4.03 and is free to upgrade via download from Kawai. The rack offers all the same power and flexibility as its keyboard counterparts. To get a more hands-on-knobs control of the K5000 (like the K5000S) there is a Knobs Macro box.
The K5000R is an Advanced Additive Synthesizer Module that combines unique synthesis capabilities and wide range of control into a single rack unit.
ADVANCED ADDITIVE TONE GENERATOR
The K5000 series updates the famous K5 synthesizer tone generator and its unique additive harmonic synthesis approach. The Advanced Additive Tone ' Generator contains 32 source generators, which depending on how they are used, can yield up to 32 voice polyphony.
PCM samples can also be mixed with additive sources. As few as one or as many as six sources can be used to make a single sound. For example, a PCM wave of a piano hammer can be superimposed with the sound of the piano string created by additive harmonics.
128 BAND FORMANT FILTER
A new addition to the Advanced Additive tone generator is the 128 Band Formant Filter, which can used as a Parametric EQ or several other con?configurations. The Formant Filter is completely controllable by envelopes or LFOs.
The K5000R Programmable Arpeggiator, features a wide range of control, ideal for use in Tekno and other modern musical styles.
DIGITAL EFFECTS SYSTEM
The K5000R contains an advanced digital effects processor (DSP), which allows four individual effects of chorus, delay, distortion, etc., in addition to reverb and a graphic equalizer.
When playing a single sound, individual sources can be routed to individual effects; when playing multiple sounds in Multi mode, individual sounds can be routed to individual effects.
