Kawai K4r 16 Bit Digital Synthesizer Module
This used K4r is fully functional and in good condition. The "value" slider cap and tip of slider post has broken off - It is still usable as it is.
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.
