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.
