Yamaha RX8 Drum Machine Introduction

Yamaha RX8 Digital Rhythm Programmer

Yamaha launched the RX8 in 1989 as a replacement for the RX7 and to be Yamaha's first drum machine using 16 bit PCM samples. In the late eighties there were several successful 16 bit drum machines available, the Alesis HR16 and HR16B as well as the Roland R8 and R5 to name a few, but the RX8 was still able to carve out a niche in the market of the time.

Yamaha RX8 FYI

  • Marilyn Manson used the RX8 from 1989 to 1990
  • There was at least one book written specifically for the RX8. Written by Bobby Maestas and released in 1989, the book was titled "Yamaha RX8: Drum Machine" (ASIN B0007259IO).
  • It is often said that you can add PCM sounds to the RX8 via the card slot in the rear. This is false. The rear slot is only for sequence data to be stored on Yamaha MCD32 RAM cards.
  • The RX8 has the ability to play any of its on-board samples in reverse.
