The Gritty 80s Digital Synth Nobody Talks About | Kawai K1m


video upload by Ian Dixon

"The Kawai K1m is a 1988 digital synth module with no resonant filters and no built-in effects, but it still has a distinctive late-80s character that makes it much more interesting than the spec sheet suggests.

In this video I take a first look at my Kawai K1m, explore the four-source sound architecture, PCM samples, additive-style wave building, joystick control, factory presets, multi mode and external effects, then try building a new patch from scratch.
