Yamaha PSS-780 plus PSS-580 - Double Portasound FM action!

Music: “Architects of Magnetism“ (C) Copyright 2021 Alfonse Download the track here: Yamaha Portasound PSS-780 and PSS-580 MusicStation FM keyboards (1989) The PSS-780 and PSS-580 were a cosmetic update to the PSS-680 and PSS-480 which had come out the previous year - the 780 also added a few new rhythm patterns and a pointless re-numbering of all the voices, but they all have the same sounds. This series of keyboards has a 2 operator FM synth on board, which can be edited via the limited Digital Synthesizer parameters on the front panel. More than that, it also has Midi In and Out (as well as Midi Thru on the 680 and 780) which gives you the capability to link keyboards to each other and to other gear, as well as access even more parameters via MIDI SysEx messages; editing software exists to modify and build your own patches. All synth sounds you hear in this track come from the 580 and 780 and custom patches were made using M
