“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 visit listing 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 visit listing 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 visit listing 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 visit listing 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 visit listing 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 visit listing 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. ” Click here to visit listing on eBay

“Keyboard is in okay condition on the top. Sides and bottom have significant damage. Turns on but the features are not work consistently. Missing disc drive would most likely be best for parts.

“This Synth has been a workhorse in my studio for several years but I need to make room for my other keyboards. The sampled instruments are very authentic and it produces a warm analog sound. I’m including all the factory disks plus some bonus purchased disks that ranged in price from $40-70 each. The Yamaha damper pedal is included. There are two rare factory manuals and two rare programming guides for the elements. The 16 track sequencer is wonderful and the drum kits are excellent. This machine has incredible programmability for making any digital patch you can imagine. I have an electronic background and the only thing I had to do was replace the disk drive belt.” Click here to visit listing on eBay

“Here’s a chance to buy my Yamaha SY77 FM synthesizer in fully working condition. All buttons work, back up battery good, screen backlight good, floppy disk cleaned and fully working.

I regret selling her as she is so powerful but I don’t have the space for her now. Never been gigged, studio use only and kept covered when not in use. This keyboard is more powerful than the DX7 and can be loaded with DX7 patches.
No user manual but it is readily available as a download online.” Click here to visit listing on eBay

” Keyboard is in good physical condition, has imperfections on it. Some cracks in the plastic along with scratches etc. Keyboard powers on, the bitch getting display says “Warning: change internal battery” most of the buttons prompt reactions on the display screen. Pitch and modulation 1/2 Wheels physically move properly and change the sound. Output volume 1 and 2 both move properly and work correctly. The dial is kind of wobbly, spins but not that smoothly. Data entry slider moves up and down, voice, multi, song, pattern, utility and EF bypass buttons all light up and prompt different reactions on the display screen. F1 through f8 buttons move physically as they should. All lights on the memory/bank section light up. Numbers 0 through 9 on the keypad section all work and display the appropriate number on the screen. Exit button works. Outputs that have been tested include output 1, left and right. Output to, left and right and headphone out. Contrast dial adjust the contrast on display. All the keys feel loose, the highest key sticks a little, F#, and G# above middle C feel a little tighter then you have the keys. ” Click here to visit listing on eBay
