    "summary": "Yamaha PSS 590 + Patch Bay Mod. Yamaha. PSS 590. Keyboards and Synths. Keyboards and Synths \/ Synths \/ Keyboard Synths. available from reverb. price range 200.4 USD. condition Excellent. The Yamaha PSS 590 is a rare 1990 digital keyboard which implements Advanced Wave Memory synthesis- the use of real world instrument and voice samples which are looped and\/or blended with digitally generated sound. The unit features a custom built 25-point ROM processing patch bay with four preset FX switches. This feature unlocks an endless array of other-worldly soundscapes, bizarre loops, weird sample hybrids, drones, warped digital distortion, garbled and staccato FM sounds, ethereal effects, powerful unison patches, strange percussion hits and grinding bass tones. When utilising the patch matrix, each configuration of the included stackable patch cables (with inline on\/off switches) produces an often multitimbral range of sounds across the keyboard. The percussion pads and onboard rhythms are also affected. The capacity for the generation of unusual pads, noise and percussive hits is immense; this modified PSS 590 is a source of distinctly different sounds which any alternatively minded electronic producer will find inspiring. The keyboard functions as normal when the patch bay is not implemented. Specs: 25-point ROM modulation patch bay. 4 preset effects switches (momentary and latching capabilities). 4 stackable patch cables with custom inline on\/off switch.
