This looks more like an amp than a mixer. The built-in rhythm machine gets the post. This would be a fun item to show off in the studio. "Check out my new amp", then flick on the rhythm section, or route a sequence running on your other gear through it with the volume down, then say "I wonder what's on the radio", mute your main mixer and switch over to the Optonica, "Oh it's me!"

"The MX-1000 is an extremely rare product, it is a mixer, an analog reverb unit & a pre-programmed rhyrhm machine.

Warm-sounding reverb, deep sinking echoes, and saturation sounds unique to analog mixers.
Rhythm machine sound like Roland CR-78.
You can listen to these wonderful sounds on youtube.

This is the first post to feature the MX-1000. Curios what the rhythm circuits are based on.
