Platter Play

Melodic scratching: the pads play musical notes by driving the platter. On the Rane One it's the third mode button, printed ROLL.

Load a tone or a sustained sound on the deck, and each pad re-pitches it to a note in your chosen key and scale — so you can play basslines and melodies with the platter as your instrument.

Pads, keys and scales

  • 8 pads play 8 notes of the selected scale; 3 note banks extend the range.
  • Key, scale, and octave are set per deck, so each deck can play in its own register.
  • Pad LEDs are note-colored, so the same note always lights the same color across banks.
  • Notes run bottom row first: the bottom pads play the four lower notes of the bank left to right, the top pads the four higher — low to high reads like a keyboard, bottom-left to top-right.

Note order on the pad grid: bottom row plays notes 1 to 4 of the bank, top row plays notes 5 to 8

Output modes

Platter Play can produce its notes two ways — set in Platter Play Settings:

OutputHow it works
"Motor (spin the platter)"Physically drives the platter speed — the classic tone-play feel, scratchable
"Pitch (shift the audio)"Shifts the audio digitally, platter untouched
"Auto (key lock decides)"Uses key lock's state to pick the right one

Chord Voices (Poly Mode)

Turn single notes into chords, per deck:

  • Adds the 3rd and 5th above your played note, with adjustable cut-in points and curves — so chords swell in as you open the control.
  • Control source: the crossfader or an expression pedal.
  • Trigger options: on pad press, on fader open, or on pedal engage.
  • BPM Sync rhythmically gates the voices, with divisions from 1/16 up to 1 bar.

Expression pedal

Plug in an expression pedal and use the Learn button in Platter Play Settings: press Learn, move the pedal, and it's mapped. The status line walks you through it.

Settings

Settings → Pad Modes → Platter Play ("Platter Play Settings"):

  • Scale and key selectors per deck
  • Output mode (see above)
  • "Apply Scale to MIDI Keyboard" — an attached MIDI keyboard follows the same key/scale
  • Display note names as flats (Db) instead of sharps (C#)
  • Chord Voices and pedal setup

Secondary mode

Pressing ROLL again while Platter Play is active switches to User Mode.
