“Selling this rare MTI auto orchestra drum machine with all necessary pedals included. Sounds killer! Drums are working perfectly. A few pots may need cleaning but all function. The sustain on the bass may need attention the pattern will fade away if you don’t keep your foot on the pedal and that wasn’t how it functioned when I first got it. Super hard to find one of these and this one is in decent condition, don’t blow it.” Link
“Vintage 70’s MTI 16R Auto-Orchestra analog percussion synthesizer, Brain is a multifunctional unit with 16 different rhythms with variations for each, right foot pedal for start/stop, 7th chords, minor chords, and minor 7th, Volume Pedal, and left foot base chords C through C, the high C on base notes was removed when it quit working. Don’t need anyway but would be easy to get and replace. Serial #590. This is a very easy machine to learn to play, I played it for years for small parties and clubs leaves your hands free to play other instruments. Select your rhythm, set you speed, select intro and hit start in whatever key you wish, Organ, Piano, Base and various drum features along with all types of variations. Hooked it all up recently and it all still works, sounds really good with base played through base amp and the rest through a PA system. It has a few blemishes from hauling it around but nothing major as pictures indicate what you see is what you get. Cost over $2000 when purchase new, can’t find owners manual but will send it later if I do. Getting hard to find these One Man Bands.” Link

” Up for sale is my MTI Auto-Orchestra band in a box. As of now it does not work as in it does not power on. I’m assuming the fix would be relatively easy for the experienced tech of this vintage synthesizer.. This unit has never been opened up and fooled with electronically as long as I have owned it, which is about 19 years or so. The unit did work for me some years ago. The unit is in very good shape for its age. Some minor scratch and dings, a couple stickers that have been on it since I was gifted the MTI. It also has a stencil of the bands name who it belonged to before I was gifted it from one of the brothers who names is on it. Notice the picture of the tripod clutch. It is broken. It still holds the MTI but will not tighten down. All the multi-pin cables and connectors are in good shape. No bent pins, fraying or broken jacket.
The unit comes with
Volume / controller remote pedal
Original Manual” Link

“The machine has been setting around as a spare. It’s fully functional, although not real pretty. The “dashboard” drum fill/break button is broke, but the fill/break remote function still works using the remote switch. (I never used the switch on the dashboard). There are digital lights to indicate the rhythm/tempo selected. Some of those little red lights don’t display correctly, but one can still tell what the number of the tempo (BPS) is. On the Bass pedals, “C” has been removed…. but there are TWO on the board, so no great loss. The guy I got it from didn’t need 2 “C”s, but had use for the button! The Start/Stop pedal (that also includes Minor, Minor 7th and 7th Chords, did double as a volume/wah wah pedal. The plastic frame where the pedal rocked back & forth broke… Now it is a fixed position pedal (no more wah wah), but the rest of it functions as intended.” Link
“In good cosmetic condition and excellent working order. Minor scuffs/scratches to outer case; pedals showing some wear/oxidation; volume pedal has had some damage to the switches – now repaired, but delicate; main pedalboard has had some damage to one corner which has had a rudimentary repair. A rare chance to get this extraordinary electronic one-man-band with all accessories.” Link

First, it only comes with what you see in the pictures.. The main unit with all of the controls and a foot pedal. These things did come with a bass foot pedal which was how you added and controlled the bass and strings sections. Without that pedal, you cannot trigger those sections.
The main unit is missing all of it’s screws that hold the front panel and side input/output panel on. They were taken off of the unit years ago when I first picked this up, and have since been lost. I originally picked this up as a project, but I’ve never had the time to invest in fully restoring this machine.
As you can see in picture 4, the side panel is loose from not having screws and the bass pedal 14 pin connector jack is also loose. You can still plug it in if you have or find the MTI bass pedals, but the jack is not secured to the panel.
The good news is, the drum machine section does seem to work and sounds amazing! It sounds a lot like a Roland CR-78. It even kind of resembles one. If you just restored this for the drum machine section, you would have an amazing rhythm box at a fraction of the price of what CR-78’s are going for these days.
Right above that tempo knob you can see a little jack for plugging in a rhythm module. I’ve seen a few different versions of this machine, and this is the one with that module jack so if you have or can find any of those rare rhythm cartridges, you can plug it in and access additional rhythms! I do not have any rhythm cartridges, but they do occasionally pop up here on eBay.
There is a sheet stapled to the inside that has some schematics and diagrams on how to calibrate the sounds on the boards. It will certainly come in handy for anyone who picks this up to restore.
That’s all I can think of. I hope this accurately describes the unit for anyone interested, so there’s no surprises. I’m hoping someone can fully restore this, or at least use it’s pieces and parts combining two units. I’ve had this thing for a while and I love messing around with it, but I am in the process of slimming down on my equipment so this has to go!” Auction ended. Click here to browse on eBay.
“This is a nice working MTI Auto Orchestra rythm machine. It comes with chord pedals and volume pedal which they are not much without these. This machine also was equiped to use a cartridge to add a bunch more rythms. There is one cartridge included. There are two items of damage that can be seen in the pictures. One is on the corner of the lid where the covering was tore and glued back and the plastic top of the volume pedal has a crack which does not effect the use of the pedal, it works fine. It is a very nice example of one of these great machines considering the age. It sounds great both for rythm and chords. I have it listed with no return simply because if you want one of these there is no reason to return it and I have no further use for it. It comes with power cord and the cords for volume and chord pedals are on them. Thank you and good luck bidding. Serial # 02535” Auction ended. Click here to browse on eBay.
“Rare and unusual drum machine
Made in USA built in New York Unit was tested and the drums work but was not able to get the
bass synth and strings to work
Properly, from what I read you need a bass pedal or keyboard to connect to the side to get the bass and strings to work
But the drums do work and sounds just like a Roland CR-78 very cool
I believe these had some options as I can see on the side
It states on these unusual plugs
Touch plate, volume pedal
Also there is individual outputs and a main plus a instrument in & out.” Auction ended. Click here to browse on eBay.

“The 16R is a rare analog drum machine with a built in bass synthesizer (often compared to a TB-303, though I think the MTI sounds more raw) and chord accompaniment. This unit has the memory expander, providing four times the number of stock rhythms. Check out some of the rhythm names–the odd translations and misspellings provide almost as much entertainment as the sounds that come from the box. As a drum machine, the MTI is nice and flexible; it has cancels and rolls and a volume mixer. Sounds very cool.
This unit is in very good cosmetic condition and works 100% perfectly. The accompaniment pedal is included, but is missing one foot switch. You can actually just play the synth bass by itself, using the pedal.” Auction ended. Click here to browse on eBay.
