Bonedo Synthesizers Take Us from PS1 to Genos: Yamaha’s Entertainer Evolution in Overdrive

Bonedo Synthesizers throw us into Yamaha’s time tunnel, starting with the PS1—a mini-keyed, beige beauty that looks more like a ‘70s toaster than a synth legend. Early models like the PS2 and PS20 start bulking up, and by the 1980s, Yamaha are already pushing out a full family of keys, with the PS30 topping the pile. It’s a parade of plastic, but don’t be fooled: these boxes set the stage for everything that followed.

By 1984, the PS6100 lands, rocking 61 keys and a now-legendary FM engine borrowed from the DX7. Italian designer Mario Bellini gives it a slick new look, and MIDI makes its first entrance—finally, you can chain your gear like a proper studio rat. The tour blitzes through the PSR6300 and beyond, each model stacking on more features and a little more attitude, as Yamaha’s design DNA gets locked in for decades to come.

Yamaha doesn’t just stop at making beige sound machines—they start packing in real innovations. The PSR4500 shows up with a number code system for selecting voices and styles (type 00 for piano—simple, if you don’t lose your cheat sheet). More wild is the roll bar modulation—no wheels, just roll your hand and mangle away. It’s a bold move, but, like all good synth oddities, gets dropped in favour of classic wheels before the ‘90s hit.

Sampling tech creeps in, giving the PSR series a sonic boost and a glimpse of things to come. By 1991, the PSR6700 is a chunky beast with 76 keys, a floppy drive, and a display that’s finally more than just numbers. Want to store your data? Floppy disks are the future—until, of course, they’re not. Auto-accompaniment gets real, variation buttons appear, and Yamaha’s keyboards start looking a lot less like toys and more like the street weapons we see today.

Yamaha’s entertainer boards aren’t just studio curios—they’re built for the stage and have the scars to prove it. The PSR8000 was literally called the ‘Shamp’ and you still spot them on stages, battered but kicking. Karaoke, lyric displays, and vocal harmony options turn one-man bands into full-on rave bunkers.

Mid-class models don’t get left behind either. Features trickle down, so even the PSR90 and 1700 get some love: filter morphing, orchestration controls, and more real-time performance tweaks than most producers will ever use. Yamaha’s design philosophy is clear—innovate at the top, spread the goods downstream, and keep everyone’s fingers moving.
