The Kawai K3 is a hybrid synthesizer with two digital oscillators and analog filters. Its architecture and sound is similar to other hybrid synthesizers that it competed with, the Ensoniq ESQ-1 and the Korg DW-8000.
The K3 has a selection of 31 waveforms available plus one user-defined waveform that is built using additive synthesis with 32 harmonics that can be set at a level from 0 to 31. A second user-defined waveform can be stored on a memory cartridge. Kawai later created the K5, a synthesizer based entirely on additive synthesis.
It uses SSM2044 chips for its filters.
The K3 is available in rackmount form as the Kawai K3m.
