“Plays great, with a few quirks since it is vintage equipment. What I’ve noticed are things that are fixable: one sticky key, volume sliders are a little scratchy, and the headphone jack has to be fussed with to work properly sometimes. Haven’t tested all functions like the jacks and the floppy drive.”

“Excellent Vintage Yamaha SY77 Music Synthesizer Made in Japan Works great. Condition is “Used”. Local pickup only.

I have no way of testing the floppy drive or Midi outputs and inputs. But it turns on, I can switch patches, and make sound through the headphone input. One little problem is that the D# an octave above middle C gets stuck. It makes sound, but it gets stuck so you have to lift it up to make it stop playing. I’m sure this just needs some cleaning and tlc. Otherwise everything works great.”

“I installed a gorgeous new black and white screen, a long and laborious task that is worth paying someone else to complete. Because the new screen is installed, there is no annoying converter whine. The keybed is fantastic, and there are no issues with it – the keys all work, the aftertouch feels great, and the velocity works perfectly. I’ve experienced no jitter/noise with any of the faders or the jog wheel. Comes with original Yamaha sustain pedal, as well as the SAX 1 and DRUMS 1 wave and voice cards. The onboard sequencer is very similar to Yamaha’s QY line (think Squarepusher), and integrates very well with the internal RCM synthesis engine.” Click here to visit listing on eBay

“Yamaha SY77 Synth/Workstation , if you are looking you probably no more about it than me. I bought this from Facebook market place without being able to test but told it all worked. It doesn’t….. so here are the good and bad points that I can tell

Bad or not so good:
Not all the buttons work when pressed
The disk drive doesnt make any noise or light up
Few of the sounds are available are not as you would expect, i.e piano sounds like a drone, but drum sounds work ok.
On some voices / sounds the screen shows random text, Im not sure why.

Good:
It turns on and boots up fine.
It makes some sounds.
The data dial and sliders all seem to work.
Some of the push buttons work.
The outside of the keyboard is pretty good and all a few small age related marks.
The keyboard action on all keys seem fine. “ Click here to search for synths on eBay

“Anyway this thing is in pretty good condition, it sounds amazing and responds predictably to all incoming midi. I paid a guy to install the usb floppy emulator but haven’t figured out how to wrk it yet. Ive been loading sounds and setups via sysex. This thing is a monster, especially with the ipad control apps. I’m selling just because I got the rack version because my studio is super tiny b I’m not much good at keys. It sure has a great keyboard though so if you can play at all, this is your synth. Its very responsive even to light touch. Not real sure what else to say, the backlight isnt working but thats an easy fix according to the internet. Guess thsts about it. ” Click here to search for synths on eBay

“This keyboard works but is well-used as you can tell from the pictures. There is a crack on one corner. It has a headphone jack, three MIDI ports, and plugs for both a foot controller and a foot switch. It comes with a carrying case with a shoulder strap. The case is dirty on the outside from being in the garage.” Click here to search for synths on eBay

“USED YAMAHA SY77 61 KEY WORKSTATION KEYBOARD SYNTHESIZER with ATA ROAD CASE
Just obtained from a large backline rental company that was closing up shop.

In great condition, very clean all around.

New internal battery just installed.

Tested and working, all functions working fine.

Probably could use a new backlight for the display as most keyboards this age do. Display is clear and easy to read.” Click here to search for synths on eBay

“Yamaha SY77 in fair condition.

Cosmetically, it’s in nice shape. There are no major scratches or dents seen among the surface of the synth.

All synthesis parameters have been tested and are working great. The battery is also fine.

Issues: There is a missing slider cap, a broken key that has been glued by the previous owner, and the disk drive is unusable. (A replacement for it can be found online.)

Despite the broken disk drive, all parameters are still accessible, and the synthesizer can still write a full song, however it just can’t save the song due to the broken disk drive.” Click here to search for synths on eBay

“Hey, eBay! Up for grabs is a semi-working Yamaha SY77 61-key FM synthesizer, listed in “for parts or not working” condition. She powers on, the LCD works (though the backlight has gone out), and all 61 keys sound when depressed. Technically, she does work. The issue is that the microswitches beneath the panel buttons all need replaced, which is typical of Yamaha gear. The same thing happened to my Yamaha RS7000 and Yamaha Motif ES6, so my assumption is that Yamaha uses the cheapest and least reliable tact switches possible in the manufacture of their gear. I don’t have time to disassemble, desolder, and solder in new switches, so I’m passing this project on to you and selling her at a loss! Also, I have no way of testing the 3.5″ floppy diskette drive built-in to the unit, but I’m sure most people will replace this with a USB FDD emulator. ” Click here to search for synths on eBay

“This is one of the greatest, most underrated synths of all time. Functionally perfect, all keys, knobs, sliders, and buttons work. The display is still nice and bright, the disk drive works great, and I’ll even include some SY77 preset libraries on floppy disks! Cosmetically, there is a minor chip on the lower left corner of the keyboard chassis, has no effect on sound or operation. Power cable, manual also included.” Click here to search for synths on eBay

“For sale yamaha SY77.

For parts or repair.

Fully working besides DM1 board.

I fitted new battery but there is an issue with one chipset. Needs to be reprogramming. I replaced that board from my SY77 just for check and synth worked fine so if someone have good DM1 or some skills to repair the board will be fully working again :)” Click here to search for synths on eBay

“Very good cosmetically overall – Can be used as it is but has some non-critical issues – the case bottom/end cap is missing a small section as shown in the last photo. LCD display backlight is out and there is small darkened spot in the LCD display. Battery needs replacement. Also, part of the assembly for the power cord is out of the back. No effect on function but it should be re positioned in the body.

I believe that due to the battery being dead, settings are lost when the synth is powered down. When its restarted, they have to be re-set as they default to some wacky values – for example, the master tuning defaults to +63. Also, I am not well versed in this synth, but I have to mess around pressing different buttons before it gets to the mode where it sounds. Once it sounds, it plays great, sounds amazing. Losing the settings should resolve with replacement of the battery. ”
