Sequential Circuits Prophet 600

“This vintage synth exhibits slight signs of cosmetic wear consistent with its age but remains fully operational and functions as intended.

I replaced the key contacts, two weeks ago.

The synth is missing 1 screw on an end panel, as you can see from one of the photos.

I have had this synth for about 20 years and hate to see it go. I just have too much STUFF and I need to let some things go to a new home.” Click here to visit listing on eBay

Sequential Circuits Remote Prophet

“This Prophet Remote serial number 4 has a completely reversible MIDI modification using a PreSonus PS-49 midi keyboard. It currently provides note on/off with velocity. More importantly it reduces the overall weight by just over 5lbs which brings it down from 13-14lbs to just over 7lbs in total weight.

I will ship the remote in the stock configuration since the PreSonus keyboard is much lighter. When the PreSonus keyboard is mounted in the case the original circuit board and switches will not fit and needs to be kept out. This modification while providing note on/off and velocity is incomplete. The next step would be to wire in the 3 mod wheels and create a new circuit board to provide access to the 4 pots, data slider and other buttons. If you’re able to finish up that project you’ll have a cool vintage MIDI keytar.

Vintage Sequential Circuits Prophet remote for the rev 3.2 Prophet-5 and comparable revision Prophet-10. Uncommon 49 key, 4 octave C-C pratt-reed j-wire keyboard. Components look to be intact, but is being sold as is. The keyboard will likely need buss bar and j-wire cleaning as well as new rebound bushings.

the remote also has three wheels of which pitch self returns and a switch matrix similar to the Prophet-5/10.

Based on the physical condition and the above I’m selling it below Ebay prices. Note it’s a heavy item so shipping is slightly higher but flat rate.” Click here to visit listing on eBay

Ensoniq Mirage

“Ensoniq Mirage DSK-8 with Gotek floppy emulator. The previous owner put in a new fuse, cleaned the contacts, and installed the Gotek floppy emulator. For some reason the little screen is displaying data upside down although that didn’t bother me. I was told it has something to do with the setup of the device which can be tweaked but I’m not an expert on Gotek emulators. All the buttons and keys work, it loads samples from the USB with no problem (you can hear me going through some of them in the video). Clearly for a keyboard released in 1985 it has several scuffs, scratches etc as you can see in the pictures. However none of them affect its play-ability.

Also included are 3 floppy disks with sounds and the original disk drive, although I was told that it doesn’t work anymore hence why the Gotek was installed. But if you want it you can have it.

I know what this sampler keyboard is capable of and the filters on it are nice, but it’s not my cup of tea hence why I’m selling it!” Click here to visit listing on eBay

and I think it is very effective in approaching newage

and vaporwave sounds from synthesizers rather than sampling.

Roland Super JX

“This is marked as Parts/Repair due to issues with some of the buttons not functioning properly. The actual keyboard keys are fully functional even the after touch feature (which can go on these). The patch buttons (that change between the various voices created) are all functional (sometimes can take more than one press), so you can get all the different sounds out of it but of the remaining buttons, maybe 1/3 are functional (the num pad included). The dial, the analog nub, and all the sliders on the left, are totally functional. Aside from these issues, the synth is fully functional and sounds absolutely gorgeous.

I haven’t even cracked it open to take a look, so maybe these are easily repaired, but I would expect to have to replace the switches to get it back up to 100% functional. ” Click here to visit listing on eBay

Korg Poly-61

“**Local pickup only**

Here we have my

Working KORG POLY-61 Vintage 1980’s Synthesizer Keyboard

I have had this a long long time, and over the years it has seen more action than Axel Rose.

Over the years I have had hard Red Oak sides put on, as the chipboard that was originally there was just falling to bits as they all do.

I have not used it for over a year, but it is fully functioning. Just needs some switch cleaner in the volume knob as it is a little scratchy when turned. With time and use this should dissipate.

Also, where the modulation/Pitch bend joystick is, the panel does move a bit. It has done this since the sides were replaced but it does not affect playing or using of the joystick. It could use some shorter screws in it I think. Just never bothered with it as it did not detract from its use. Just thought I would mention it as someone may want to fix that.

Other that what I have mentioned , it is working as it should.” Click here to visit listing on eBay
