"This is the very rare MTI Auto Orchestra AO-1 drum machine / bass synth / strings / chords accompaniment unit + bass pedals, volume pedal, stand and cover for the front of the box.This thing is pretty insane. The Drum machine sound is off the hook!
Here is a video I took of this actual machine - VIDEO. In the video, the unit is connected straight to my iPhone using an iRig adapter with no pre amp or anything in between.
A lil about the MTI AO-1 - It has many different drum presets and each preset button has 2 variations. Each drum voice has its own cancel button (!) so you can choose whatever elements of the beat you want (say just kick drum, kick + snare, cancel the cymbal, cancel conga, etc.) so the combinations are pretty much endless.
Very powerful bass sound. reminiscent of the TB 303. Strings section and chords section.
When no drum preset is chosen, you can play the bass and strings manually using the pedals. When a preset is chosen, the pedals will determine the chord.
The volume pedal is not the original pedal. It is a modified Crybaby pedal. In the original pedal, you were able to switch between major and minor. With this pedal you can only control the volume.
The volume knobs of the different sections can be pulled for constant signal. When they are pulled, the volume pedal no longer controls the volume.
Also included is the original stand and the cover for the box.
The unit is fully functional. It has a little bit of hiss as expected from a 30-40 years old unit."
