Keyboard is in great shape. Sounds Amazing!!

Overview: --------- The Kawai K5000 comes in three versions designated by a suffix of S/R/W for synth, rack, workstation. This review concentrates on the K5000S.

The K5000R is identical except for not having the keyboard and maco-buttons, being a rackmount unit.

The K5000W contains the same synthesis engine but also has an additional GM PCM-based synth with 32 voices and a 40-track sequencer. It lacks the macro-buttons

For the K5000 R/W you can get a separate macro-button box.

The K5000 voice isn't too far from the "standard" mould for general synthesizer arcitechtures, meaning that it has a signal chain consisting of oscillators, filters and amplifiers with modulators to go.

However it is also *very* special in that the oscillators are of the additive variety (alternatively you can choose a PCM oscillator). This means that they synthesize the waveform dynamically from a series of 64 harmonics. Each harmonic has it's own loopable amplitude envelope, and the additive oscillator as a whole can be modulated. This means that a dynamically evolving spectrum can be synthesized. You've probably seen those fancy 3-D audio-plots (FFTs)... The K5000 can make these "mountains" of sound.

T are actually two series of harmonics, one SOFT and one LOUD, which can be crossfaded by velocity - they share the same 64 envelopes.

Then t are the filters - first is a 128 band formant filter that can be used to shape the dynamic spectrum from the additive oscillators. The formant filter has its own envelope or LFO; you must choose between one of these, but the envelope is loopable.

Next is the DCF, a more tradiational filter with low and high- pass modes. It is a 24 dB/octave filter with variable resonance, and you can make it scream in self-oscillation. The DCF also has a gain control on its input.

Finally t is the DCA with its own envelope and panning.

To knit it all together t is a global LFO and a good selection of modulation sources and destinations.

This makes up what Kawai calls a "source". A "patch" can contain upto 6 sources and a "multi" can contain upto 4 patches. At patch and multi -level you can arrange the sounds in 4 zones/layers. In multi-mode you get a 4 part multitimral synth.

The patches/multis can be routed through 4 effect processors, a reverb and an EQ before leaving the box through two stereo pairs.

In the K5000 S and R models you can store 128 "patches" and 64 "multis", but it has a floppy drive so t's plenty of cheap storage available... In the K5000W the number of memories are doubled. The K5000 R/S can take an optional memory upgrade to get the same ammount of patch-storage as the K5000W. amp mod output +-----------------+----------------+ | Pan |-D +-------------+------+-------------+ | |

left rightoutputs --> The modulators come in two classes:

1 - modulation sources that are "destination-routed", fixed routings with ammount control at the destinations

2 - modulation sources that are "source-routed", variable routings with routing and ammount at the source

In the diagram above, the various possible modulation destinations are marked with D and/or S.

The destination-routed modulators are:

keyscale and velocity

Posible destinations for ks/vel are: (Kawias abbreviations: DHL = harmonic level, = DHE harmonic envelope(s), DFL = formant filter (the D probably stands for digital as ususal...))

ks -> DCO pitch vel -> Pitch envelope level,time ks -> DHL gain vel -> DHL gain ks -> DFE env-ammount vel -> DFE env-ammount ks -> DCF frequency, attack, decay1 vel -> DCF frequency, env-ammount, attack, decay1 ks -> DCA level, attack, decay1, release vel -> DCA level, attack, decay1, release ks -> LFO DCO-amount, DCF-ammount, DCA-ammount

The source-routed modulators are:

fixed macrobuttons 16 fixed destinations/levels user macrobuttons 8 destinations/levels global LFO, 3 fixed destinations/levels (DCO/DCF/DCA) modwheel, 2 destination...
