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.

Tengo uno desde 1991 y fue mi primer synth. Me encanta su sonido limpio. No me voy a deshacer jamás de él.

Gre za res hudo klaviaturo, z neomejenimi možnostmi izdelave zvokov, s svojo starostjo in analogno digitalno mešanico pa sije v svoji veličini. Nekje sem prebral, da gre za revežev M1, ampak ne bo držalo...To je klaviatura za entuzijaste in eksperimentatorje vseh oblik in veličin od progressive sound do techno house varijant. Palce gor, če jo kje vidite jo zgarbite, zaradi nje vas bodo gledali drugače...

I had one of these in the early 90s. The drum sounds are dated, but useful. The pads are really sweet, although as someone else mentioned the k4 can be a bit noisy. I loved playing live with this keyboard-the warm sounds were awesome. This is also a nice set of keys to take to a gig b/c it's light weight. After lugging around a Korg DSS1, an Emax and K3 back in the day, the K4 was just heaven! Unfortunately, I sold mine when broke in grad school, but will buy another soon. Great vintage keys!

This was my first synth, i bought it used in 1995 from a proffesional band in my country (actually they recorded many songs using it). I still own it and will never sell. Pretty unique synth, its like the robot from "forbidden planet", technologically aged but with a very own character. Soon i will buy a roland g6, im looking also for and old oberheim, but will never get rid of this one.

I noticed issues with some of the factory sounds when I was in a recording studio. The engineer pointed them out (pops and clicks). After editing I made them acceptable. The drum section has a sound similar to what is used in rap music. Editing is easy. The airy string sounds are its forte.
