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.

@ pete: Check to see if it was set to local off. Hit "SYSTEM" a couple of times until you get to the page that says "LOCAL: __". if it's set to OFF, then turn it ON and play the keys. You should hear something now. If you hear nothing (or if it's already ON), then something else is going on and it may require you to have it looked at.

Good Luck

Hi there
I just got an old Kawai K4. I plugged it in but no output. It lights up but there is no output either from the phone jack or any of the other outputs. Any suggestions?

David Wright's 1991 electronic music CD Marilynmba was done using only a Kawai k4 synth multitracked. Considered a a classic em album!
