"I've always been a bit of a rebel, and I tend to do the opposite of what everybody else is doing. Recently I started using a Yamaha RX11 drum machine, then changed down to an RX15 because the difference wasn't all that great for the sort of music I was doing. It does help having an all-Yamaha setup with the RX15, DX7, TX7 and the QX7 sequencer, but the drum machine takes a back seat, being used more as a part of a sequence than as a drum backing. And of course the wind instruments are always there."

"We have a Yamaha RX11 drum machine but I'm a bit disappointed with that. For a start the memory is a bit limited, and because a drum machine is used like a sketchpad, it's very frustrating if you can't get enough bars into it. We use a LinnDrum with standard chips - our producer has some alternative sound chips too - and a Roland TR707 and 727 which are really good. They're amazing for the money, and we've just got an Octapad (Roland's MIDI drum pad set) which allows you to record drum patterns through MIDI onto the QX1."

The BBC Radiophonic Workshop is documented using the Yamaha RX11 drum machine in their diary, as referenced in the Whitefiles source.

Ian McNabb talks in this interview about using a Yamaha RX11.

There is an RX11 clearly visible in this video.

"For instance, on the Melba Moore album I used the Yamaha RX11 drum machine with the individual outputs, which is MIDIable. I would write the song pattern on the RX11 and then MIDI it up to something else. I was MIDIing to an Emulator II which had samples on it which you could tune. It's basically using it instead of a Fairlight except you're not restricted to using Fairlight samples or Emulator samples. You could mix the RX11 sounds with the Emulator sounds, or you could trigger the DX7 with the RX11, or even an analogue synth via MIDI."

I've been through all the Roland drum machines, you know, cheap and tacky. Now I've got the Yamaha RX11. The snare sounds on it are a bit naff, but one of the bass drum sounds can pass as a reasonable sound in the studio with a bit of compression and eq. On the album me and Dave would work out the basic pattern on the drum machine and then get Ulle or Martin Chambers to take that as a basis. But on A Good Heart, although Ulle plays on it, at one point there's a rim shot and a bit of shaker from the original drum pattern, so we do things like that for percussive effects."

The drums come from a RX11 and the instruments are all DX7.
