Pics of the inside below.

"This synth has some cosmetic wear in the expected places (shown in pictures), showing its age; but all features function as they should for a normal working unit. The keyboard includes a rock solid Anvil case made to the measurements of the AX-80 to keep it safe and sound to and from gigs.

The synth has recently been serviced and checked to ensure proper functionality as per the Akai Service manual.

Fresh 3 volt memory battery installed, all 8 voice output levels calibrated via trim pots, 6 new keys and return springs installed, keyboard contacts cleaned, power supply voltages inspected, all PCB solder joints inspected (any cold/cracked joints resoldered), all ribbon cable connections cleaned and secured, all hardware tightened snug, and a general cleaning inside and out.

All voice chips are the original CEM3372 ICs with matching lot (8425) and type (B) designations. CPU ROM (IC4) is the factory D2764 D chip, noted program version I

8 Voices w/ 2 DCOs and 1 Sub Oscillator per voice"

MTI Auto Orchestra Vintage Drum Machine with Synth Bass, Footpedals and Strings

via this eBay listing

"Have a chance at this amazing, vintage fully-analog groove box. It's got three parts, a CR-78 style Drum Machine with 20 patterns and 9 muteable drum parts. It's got a acid-tastic synth-bass section. A sweet Strings section and a auto-Chord section.

It comes with it's original Volume pedal and Footpedal keyboard controller as well. Works and sounds great, it's a machine that simply brings out your creativity. There's plenty of youtube videos around of them and I think it's a great purchase for a synth-geek or a guitarist looking for that vintage sound."

video upload by Devin Belanger

"Semi-improvised synthesizer jam on the Moog Matriarch (bass sequence), UDO Super Gemini (poly aftertouch Vangelis brass & arp) & Sequential OB-6 (pads). I absolutely love these 3 synths for in the moment inspiration like this, and have been writing tons of songs with this combo. Here's a little insight into my process of jamming over a simple sequenced progression to find little nuggets of inspiration."

Sequential Prophet 5 and Roland Space Echo | Horror Movie Soundtrack


video upload by Suspect Media

"The Prophet 5 is amazing for horror soundtracks—I use it in almost everything. When it’s processed through the Space Echo, it’s pretty much unbeatable. It just has that perfect 80s sound."
