Ace Tone Rhythm Ace FR-1

   (1 review)

After their prototype the rhythm Ace R-1 was shown at the 1964 NAMM shw, Ace Tne released the Rhythm Ace FR-1. The first drum machine produced by circuit they called a diode matrix. It showed rows of pulses that would show the position of each instrument in the machine. It has 16 preset patterns and 4 buttons to manually mute each instrument cymbal, claves, cowbell and bass drum. If the user pressed multiple buttons together it can play over 100 possible rhythm combinations. The Hammond Organ Company also sold the FR-1 presets into their organ models of the era.

I have one of these, it is great even to this day. It was even used in a Gorillaz song.
One thing to point out though from the description above, the part where it says " ....and 4 buttons to manually play each instrument cymbal, claves, cowbell and bass drum." Is incorrect.
Those 4 buttons mute those sounds during rhythm playback, they are not triggers.
