Yamaha PSS 680 & 780
Full-featured FM Yamaha Portasound keyboards from circa 1988/89.


Yamaha Portasound PSS-680 MusicStation (1988)

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, Out and Thru, 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.

This track is from the ALF album...

Yamaha Portasound PSS-780 MusicStation (1989)

The PSS-780 is almost identical to the PSS-680, aside from some different coloured pads and buttons, a few new rhythm patterns and a pointless re-numbering of all the voices, and it has the same sounds as the PSS-480 and 580, which were the next rung down in the product line. All sounds you hear in this track (other than the kick drum) come from the 780 and custom patches were made using a Ctrlr panel (a software editor that communicates between computer and keyboard via MIDI SysEx).

This track is from the Once album...

A few people had commented on the amount of FX I used in the mix for some of my early demo videos, so here is the honest mix of Splendid Larryo. The raw sounds from the keyboard were recorded into Logic and sequenced, with only a small touch of reverb to give some depth (too dry is no fun) and no other external FX used on the mix.


The video guide above is based on the PSS-480, but it's the same process.
