For nearly 40 years, Yamaha has created a host of portable musical keyboard instruments under the “PSR” branding. This article sheds light on those models, from 1984 when the first “PortaSound” models emerged, right up to the present day with versatile, high-technology instruments good for both beginners and seasoned keyboard musicians.
There have been close to 150 models with the PSR branding, including very basic keyboards but also those with more high-end features. As technology has improved and prices have dropped, later models have often included more functionality at less expense. Build quality has usually been reasonable at least for amateur home use, and they are usually marketed as being ideal for younger and beginner players.
We’ve tried our best to be as thorough as possible, but with some models now long extinct, and the diminishing availability of accurate information and resources for electronic equipment from the 1980s and 1990s, we can’t automatically cover everything in great detail. We will continue to add to this page as more data becomes available. We’ll also link to other pages, both on this site and elsewhere, when good archive/comparison information and resources are available.
The first model Yamaha released in its PSR range was the PSR-15 in 1984.
Not the lowest numbered PSR created, but the first. While basic by today’s standards, it featured 49 keys (four octaves), six sounds, accompaniments with various finger modes, ability to add an expression pedal, and battery or power adapter usage.
It isn’t clear from the manual which sound generation technology was being used, although we presume some kind of PCM but not Yamaha’s much developed AWM system as this didn’t really come into its own until the 1990s. No MIDI, as this was still a very young technology in the mid ’80s and not really of much value on such a basic keyboard.
Amount of polyphony is unknown but it certainly wasn’t monophonic as it allowed for playing at least one note alongside rhythms and accompaniment sounds. Our guess is perhaps around 8 simultaneous sounds.
MIDI and Buttons
In 1985 Yamaha launched five more PSR models, with control panel interfaces containing more buttons for tone and accompaniment and other function section. MIDI ports also found their way onto the higher end models, including the PSR-50 and PSR-60.
A very rudimentary system for saving program and performance data was introduced on the PSR-60 and PSR-70, by means of connecting a tape recorder to the special “tape” audio jacks and recording data (probably much like home computers of the era did) for subsequent retrieval.
Overall functions were still quite rudimentary but we can already see an increase in number of sounds, polyphony and overall functionality.
