Rare MTI Auto Orchestra. Vintage drum machine synth

via this auction

"Here is a very strange rare drum machine/synth/strings/one man band thing. I believe it is from the 70's. These are pretty hard to find and this one is in great condition. Works great. The bass foot pedals control the notes/key of the song. You can play manual bass melodys or just hit the note so that the whole song changes keys. The other pedal contols the volume, start and stop, and minor, 7th and dimished."

VINTAGE MTI Auto Orchestra Synthesizer w/ bass pedals

via this auction
"This is a vintage machine that is much more than a rhythm machine or electronic drummer. It play chords and has about any style beat. It takes a little practice to use the pedals while playing but you can sound like a band all by yourself. It is an American built machine which was built in Garden City Park, New York by Music Technology Inc. The Model # is AO-1. Everything comes in the sale; base pedals, volume & pitch control pedal, stand, case and power chord. The control panel display is labeled as such; from top left, bass, decay, synthesized tones and strings. You may select between and 8th and 16th notes and normal or root. To the right with the blue buttons are the string selections and volume and tone nobs. The white buttons are the drum display; bass, conga, bongo, snare, slave, cowbell, high hat, splash symbol and ride symbol. Unit power button is to the right. Third row, the yellow red and green buttons have two levels of specific drum rhythms to choose from; waltz, foxtrot, blues, dramatic ballad, country rock, disco, bossa nova, mambo, jazz waltz, swing, shuffle, dixieland, fast country, rock, cha cha and rumba. The fourth and final row has tempo dial at left corner, rythym selector; drums, bass, chords and strings, break, start and stop."

"Comes with a suitcase full of accessories, like pedal, sequencer, 13 key keyboard & auto orchestra rythym cartridge which I assume the sequencer selects."

I wonder if the 13 key keyboard is the same as the one seen in this post.
