Ace Tone FR-1 (1970)
Rhythm Ace is nothing less than the very first beatbox ever made by Roland (then existing under the Ace Tone brand), and the world's first transistor rhythm machine! It included innovative circuitry to produce several different drum and percussion sounds by filtering, amplifying and mixing sine and noise oscillators. Indeed, Rhythm Ace is the father of all next drum machines from Roland, like the all-time classic CR-78 and TR-808 .
- Sounds: kick drum, snare drum, rim shot, open/closed hat, conga, bongo, clave, maracas, guiro
