YAMAHA SK30 String Machine 1979 | HD DEMO

(c) 2018 by AnalogAudio1

Synthesizer Demo of the analog synthesizer/string machine YAMAHA SK-30. I played it along with Lexicon MPX500 (reverb) and Korg SDD-3000 (delay).

Yamaha's SK-series are string machines with additional sections (poly-synth, mono-synth, brass, organ, depending on the model). The SK30 was the flagship (the SK50 was just a double manual version of the SK30). It has "ORGAN", "STRING", "POLY-SYNTH" and "MONO-SYNTH" sections, they all are mixable. The Poly-Synth section has a nice analog filter (but only one for all voices - finally it's a string synth, not 100% a synthesizer). In one of the 8' footage/saw waveforms, it even has a bandpass filter engaged. The keyboard has aftertouch, which is assignable to LFO intensity or filter cutoff (similar to Yamaha SY-1/2 or Roland SH-2000).

A nice layer-string machine! It's a big beast, it competed with ARP Quadra, Korg Trident, Crumar Multiman, Farfisa Soundmaker and Farfisa Polychrome.
