Kawai K4

Kawai K4 Image

The K4 from Kawai can be thought of as a warm and fuzzy digital synthesizer. A sample-based digital synth, its sounds are those typically weird industrial type sounds that can still be useful in lo-fi, big-beat and trip hop music styles. The sounds are 16-bit preset PCM samples of acoustic instruments. However, unlike its predecessor the K1, the K4 adds a welcomed digital filter section. This truly makes the K4 more flexible, fun and useful for today's filter tweaking music effects!

The K4r is the eight output rackmount version which has all the same features except for the effects processor. Both feature 8-part multitimbrality which is great for stacking, splitting and layering sounds. The K4 will give you strange, new and unique sounds with plenty of flexibility and analog-style sound shaping and control at an affordable price. It is used by The Chemical Brothers and ATB.

Hi K4 folk, just got a K4r again after years since i sold the last one, this one was dead as far as sound and the display only said Kawai K4r or similar for all the sounds, you can download the factory sound set from the Kawai site with a utility to dump the sysex file to the K4r, upon doing that it still didn't sound right even though the sound names where there etc, all it needed was a power off then on again and all working fine, hope that might help any future buyers of this little gem, looks like they can lose there sounds settings etc if not used for a long time even if battery is ok.

@Nick Waves:
You can combine up to 4 oscillators to create a so called single sound, and up to 8 single sounds to create a so called multi sound (for split, layer, different MIDI channels, what ever you want).

I bought a K4R module last week for 100 usd. This is a great gear. How have I been able to live without it in so many years? :) I didnt know that such a beatiful creature exists.The sound quality is amazing. I already own a Triton rack with expansions, a Roland xv-3080 with expansions, a Motif rack and a Proteus 2000. I want to buy a K4 keyboard ås well ås soon I find a one.

Hello, anybody knows how many MB of samples has got internal ROM of K4 ? I'm curious and it's difficult to find out the truth. Thanx
