Mutable Instruments Grids

Topographic drum sequencer

16 HP Eurorack module

Grids is a topographic drum sequencer that generates rhythmic patterns using a compressed representation of drum variations. It provides three drum channels (BD, SD, HH) with pattern morphing capabilities controlled by X/Y coordinates and density parameters.

Features

  • Topographic drum pattern generation with X/Y morphing
  • Three drum channels with individual density controls
  • Internal clock 40-240 BPM with tap tempo
  • External clock sync with selectable resolution
  • CV control over all pattern parameters
  • Configurable chaos/swing control
  • Multiple output modes and configurations
  • Pattern reset and synchronization
  • Compressed drum pattern algorithms
  • Low jitter clock processing

Controls & Jacks (23)

  • Tempo— Internal clock tempo control (40-240 BPM)
  • CLOCK— External clock input; overrides internal tempo
  • MAP X— Navigates the topographic map on the X axis to select rhythmic patterns
  • MAP Y— Navigates the topographic map on the Y axis to select rhythmic patterns
  • RESET— Reset input; returns pattern to step 1
  • TAP— Tap tempo button (configurable as reset)
  • SD— Controls snare drum hit density and fill amount
  • BD— Controls bass drum hit density and fill amount
  • MAP X CV In— CV input for Map X parameter modulation
  • LED 3— Indicates clock/trigger activity
  • HH— Controls hi-hat hit density and fill amount
  • MAP Y CV In— CV input for Map Y parameter modulation
  • BD Fill CV In— CV input for BD density modulation
  • SD Fill CV In— CV input for SD density modulation
  • HH Fill CV In— CV input for HH density modulation
  • BD Trig— CV input for Chaos parameter modulation
  • SD Trig— CV input for Fill parameter modulation
  • HH Trig— Bass drum trigger output
  • Chaos CV In— Snare drum trigger output
  • CHAOS— Pattern randomization control (or swing for internal clock)
  • BD Acc— Hi-hat trigger output
  • SD Acc— Accent output; fires on emphasized beats
  • HH Acc— Combined trigger output (logical OR of all channels)
