Korg 707

“Korg 707 FM Performing Synthesiser 1987. Purchased as a repair project but I now have too many and something has to give. Cool FM synth increasingly hard to find for sale. Has the same 4 operator FM chip as Yamaha DX100/27. Powers up to an almost blank screen (black squares actually) and the coloured buttons flash briefly, so not booting up properly. One black key is broken and spring terminal for the batteries snapped off as shown in last photo. ” Click here to visit listing on eBay

“korg 707 performing synthesiser for sale in perfect working order and good clean condition, bought new in 1989 from tempo music in London and owned by me ever since.
The keyboard actually uses a Yamaha licensed circuit board inside and it sounds very much like a 4 operator dx100/27 fm synth.
On the top panel it has a pitch bend and mod wheel which can be reversed if wearing as a keytar, and there is a volume control and 3 slider controls which allow you to create new sounds easily without having to delve in to submenus like other keyboards do.
This keyboard was launched by Korg just before the m1 was released and it shares the smooth phillishave appearance of the m1 with its smooth round edges and teddy bear eyes tactile push buttons.
The 3.3 volt battery was changed last year and 1 key was replaced and I had all the electronic components tested for functionality by my technician and everything is working fine.
The keyboard comes with a paper manual a power supply and software on a disc which I bought on here that will allow you to transfer sounds and System exclusive data between computer and keyboard and allows ds8 sound patches to be loaded in to the 707.
There are sound cards available but they are rare and hard to find so luckily there is a free sound editor available to download for mac and pc which will allow you to create your own voices without loads of button pressing and going through sub menus.” Click here to visit listing on eBay

“Ah, the Korg 707. This is an expandable FM synthesizer first produced in 1987. It has 49 pressure- and velocity-sensitive keys and 100 user-editable presets. It even comes with strap buttons so you can wear it around like a guitar. There are quite a few scratches on the bottom, so maybe the original owner wore it and a big belt buckle on stage. Who knows? It also features a slot for a memory card, though I’m not sure which type of card it takes, and no such cards are included.

Please note that there is a chip on the underside of one of the keys; please see photos. There also seems to be a short in the AC adaptor, which may need replaced. This will also run on six C batteries. There isn’t any corrosion in the battery compartment that I could see. ” Click here to visit listing on eBay

“Korg 707 Strappable Synth. Condition is Used. I’ve had this synth since new 1989 and for many years it was my main keyboard for sequencing and triggering my other rack mount synths. It has its own set of fm based sounds… one or two are quite good and you can also use it live with a guitar strap should you wish as it works both on batteries and power supply. The spring has gone on the first D key…. happened once before back in the 90s and I had it fixed: unfortunately it seems to have gone again. Simple fix apparently but beyond my skill set.” Click here to search for synths on eBay

“Korg 707 Vintage Synthesizer KEYTAR w/pwr supply TESTED Works -no headphone jack. Condition is Used.

I tested this keytar/synth and found all of the voices to be working. I tested everything that was east for me to test and found only the headphone jack not working. Someone had removed it. I bought a new jack perfectly matched to the others on the synth, but I did not install it. The jack will be included with the sale along with the synth/keytar and power supply. The case has lots of scratches all over it, but I didn’t see any significant cracks or chips. The LCD panel works, but it is the original low light type, not the bright replacement type. ”

“Korg’s version of an FM synth , easier to operate than yamaha FM but less complex also.

Includes rare memory card

Sounds great and can be smooth or noisy & rough , similar to dx100 in terms of aliasing and good bass sounds.

Has quick edit sliders for envelopes and timbre so you can tweak as you play.

49 keys with velocity and mono aftertouch. Pitch and mod wheels.

It has been circuit bent with 8 switches on the data lines to make some weird noises.

This sometimes corrupts patches but all patches can be backed up and restored from the memory card.

A few scratches but no cracks in the case, buttons all work. See images . Sounds good, but I have to many FM synths.”

“This Korg 707 needs about half of the buttons on the control panel replaced. It works great as a sound module, programming patches over MIDI with editor software. Until the buttons are replaced though, you will not be patching on the unit itself. Things look fairly clean inside. ”
