Synths ⇝ Kawai ⇝ Kawai K4

The K4 is the successor to the Kawai K1, but with higher-quality waveforms and a digital filter added. It was also produced in rackmount form lacking the effects DSP as the K4R.

It has an 8-bit processor to power what Kawai calls "DMS tone generation" and a patch can be built using one or two samples. It can save patches to a memory card, working with either a DC-16 or DC-32 RAM card.

The K4 uses a 12-volt external power supply rated for 500 mA of current (model PS-121G).
