Kawai K5000
The K5000 was Kawai's top of the line music workstation digital synthesizer when it was released back in 1996. It's a bold and elegantly designed synth with a large LCD display, realtime controls and incredible sounds! The look and functionality is rivals the competition from the time...the Korg Trinity and Kurzweil K2500.
Programming sounds with the K5000 can be a breeze (once you learn how) although it has over 1,000 parameters per patch! That's plenty to play with. It combines additive synthesis and PCM sampled waveforms for you to layer and combine to design a whole range of sounds. Plenty of LFO modulation, filters and envelope controls allow you to shape and morph your sounds further. On-board multi-effects add the final touch of life to your sounds.
Once you've created some sounds, there's the on-board sequencer (K5000W only) for creating songs or loading Standard Midi File sequences (via disk-drive). It has a 40,000 note capacity and 40 tracks. Real-time record and step-edit modes are available and the sequencer is pretty straight forward.
The K5000S (pictured above) adds 12 dedicated knobs for hands-on control of filter, LFO and envelope parameters. There are 4 user-definable knobs and 2 assignable switches. The K5000S also has a 40-pattern arpeggiator on-board with 8 user-definable patterns too! K5000's have been used by Kraftwerk.

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. But other controllers such as Encore Knobby or Keyfax Phatboy can also do the trick.

The sounds that ive heard that stand out the most of this board are really awesome square and attack basses and some crazy pads (reminded me of Transwave technology style pads).
I will definitely try to pick one of these up eventually - they are quite a neat combo when paired with the similarly underrated Yamaha EX7/Ex5R synths
Additive has such potential, and so much more could be done with the technique, and with the power of todays DSP chips, the possibilities are endless.
Until then, I shall hang onto my K5000R...
Nearly 15 years later, I am still amazed by the K5000s. Nothing sounds like it. The knobs allow tone sculpting both subtle and extreme. The keys are beveled for fast action and respond to aftertouch by modulating the sound further. Many patches are elaborate soundscapes to be explored.
The factory patches provide immense variety when you consider the insane warping potential of the controller knobs. Every patch is inspiring and you can find thousands more online and load hundreds at a time via a single 3"1/2 floppy.
In short, I love this keyboard. Have I mentioned the midi-syncable arpeggiator? You control the pattern (preset or user defined), octave jumping, speed, and hold via 3 knobs. No menus required for anything but patch programming.
Comparisons in sound? Well, it does a mean resonant bass growl that sounds like an analog synth overdriven with tubes. To my ears, some flowing water-like accents can be heard in many patches. I've heard it do screaming leads with shrill crushing modulation, or waves of mechanical atmospheric ambience, or even standard instuments like trumpet. Though it offers few precussion options, it defies categorization.
My only complaint? It weighs a ton, about as much as an Ensoniq Mirage. On second thought; this could discourage a hypothetical burglar from snatching it easily, so I guess the weight counts as a feature.a
So, yeah. The K5000s is rad.
