Oberheim Matrix 1000

“1000 Classic Analog Synth sounds from the Oberheim Matrix 1000! Works great (see photo with power on – Patch 745 was my favorite!). Includes all ORIGINAL manuals, cards and the original box. Only issue is cosmetic – a bent rack ear and scratches on top and bottom panels. A truly special tone module.”

Casio CZ-5000

” Very nice vintage Casio CZ-5000 digital synthesizer. The flagship of Casio’s professional line of Digital synths in the mid-1980’s, this is a surprisingly deep and unique synth. In very nice used condition – all sliders and buttons are there, all keyboard keys function. The paint and button markings are also very good. Very nice cosmetics in general, just some scuffing, smudges, light scratches and an area of speckling from use and age. With 2 original manuals (see pic), and even the original Casio carton. I have not tested all the functions (not sure how the sequencer is programmed, for example), so I can’t guarantee absolutely every control, but everything I have tried seems to be working fine.”

Teenage Engineering OP-1

” Teenage Engineering OP-1 Keyboard Synthesizer. Used. I am the original owner and unit has only been used by me.Works great. Good battery life. Comes with carrying case, keyboard layout plastic, USB cable, and 2 spare knobs. Selling because I just don’t use it in my workflow at all.

Has a slight defect as pictured that does not effect operation or performance of the synth. The defect is next to the braille on the back side of the unit. The plastic is slightly cracked. I am convinced this happened because of the stand I had the unit on, but the unit was never subject to impact. Again, the unit works fine.”

Moog MG-1

“Moog Realistic Concertmate MG-1 synth – vintage analog synthesizer in very good condition, see pics. All keys work, all sliders and knobs work. I used it to trigger it from a Eurorack modular, so CV/Gate input works great as well, stays in tune nicely. Big, fat, warm old Moog sound I can’t seem to replicate exactly with my Sub Phatty, but I don’t need 2 bass synths now. I recently opened it up to clean the grimy foam off, and upon putting it back together the far right key went askew; not sure what happened there, but the key plays fine. There is a missing silver decal off of one of the slider caps”

“This is a vintage Roland SH-101 (*Note: this is NOT the new boutique model, but the original from the 80’s). It’s been very well-cared for and looks, plays, and sounds amazing. It’s a great substitution or companion for the TB-303, as it’s capable of producing amazing sounding acid basslines. It’s also much more flexible than the TB, and can create bubbling chaotic effects, funky leads, and smooth synth arpeggios with ease. Most of all, the ergonomics are very easy to dial in new sounds in seconds”

Yamaha CS01 Project Machine

” Yamaha CS01 vintage analog monophonic synthesizer. This synth is mostly broken, and is really suitable only for parts, or only if you really like the sound of an analog keyboard that’s on its last legs.

The good news is that there are no dead keys and the outputs work.

Here’s what’s broken that I’m able to identify:

• The internal speaker is not in great shape.

• There is a quiet (but noticeable), high-pitched tone at all times, modulating up and down in pitch, like a quiet siren.

• The white noise generator is broken in a way that affects overall operation. It doesn’t reliably produce white noise on its own. In addition, an amount of white noise comes and goes at random (and especially when adjusting the VCF EG slider), even while using other wave forms (triangle, pulse, and so on). The sound is akin to laptop speakers failing.

• The VCF EG slider doesn’t seem to apply any kind of envelope to the filter: just random white noise.

• The VCO Pitch slider I believe is broken.

Does not include power supply.”

Yamaha TX216 with 4 TF-1 Modules

“Yamaha TX216 with (4) TF-1 modules. Condition is Used.

This is a vintage Yamaha Pro keyboard rack mount piece used in all the top studios from way back in the 80s…still in use today. If you are reading this, you probably know what this monster can do. This is basically 4 vintage DX7 synths in one rack, with the ability to house up to 8 total modules.

Balanced +4 pro level output for each module.

I bought this unit used, and has worked fine for me. I’m not using it much these days, so this needs to go to someone who will put it to good use.

It is not physically perfect, but is functionally perfect. Due to the age, I am selling this unit as is, with no returns, although I will guarantee no DOAs.”
