GR - Grids Sequencer

An adaptation of the Mutable Instruments "Topographic drum sequencer" module.

See the original Grids Manual [or a video ?] for more.

Grids is a 4-channel/instrument MIDI trigger generator specialized in the creation and sculpting of rhythmic patterns. The "grid" refers to a map or library of preset drum patterns arranged in a 5x5 grid - which you can steer using X/Y controls.

Typical drum use would be Bass Drum, Snare, Closed HiHat, Open HiHat (The default note numbers are mapped to these in the GM drum map).

Quick Keys Grids has many quick keys. Pressing these keys quickly jumps the display to select a specific parameter which can be adjusted with the encoder.

Keys/Commands:

  • AUX is sequencer Start/Stop
  • Pots 1-4 control "event density" (probability) of 4 instruments - values are shown on display
  • Pot 5 sets resolution (1/2, 1, 2)
  • Bottom row keys 1-8 are quick-keys for X/Y values - hold a key and turn encoder to change that instrument's X or Y value. You can hold multiple keys to change X/Y on multiple instruments at the same time
  • LEDs on Keys 9-12 show trigger activity of the playing pattern
  • Lighted Keys 13,14,16 are quick keys for ACNT/XAOS/BPM
  • Pattern keys (black keys) can load "snapshots" of density/x/y settings
  • F2 + Pattern saves a "snapshot" current state of that pattern. Patterns do not automatically save, this is a performance feature, allowing you to load a pattern, tweak it, then quickly load back to it's original state

Instrument View Mode:

  • F1 + Keys 1-4 jump to Instrument View. This shows the current pattern on that instrument (over 2 pages since patterns are 32 steps) and playhead. The LED render of the pattern will update to show each page while playing
  • Top row lighted keys(A#1, C#2, D#2, F#2) are quick-keys for ACNT/X/Y/XAOS
  • First 4 keys of bottom row will not be specially lit since they are rendering the pattern, but will allow you to quickly select a different instrument
  • F2 is a quick key to jump to params page to set Note Number, MIDI Channel and BPM
  • Key 3(F#1) in Instrument View is a quick key for Midi Channel for the instrument
  • AUX-key exits Instrument View

Midi Keyboard Mode:

  • F1 plus bottom key 16 enters into the Midi Keyboard for sending CCs or playing over the top of the sequencer. Everything works the same as mode MI
  • Hold Aux and bottom key 16 to exit out of the Midi Keyboard mode

Parameters:
Page 1 Event Densities:

  • DS 1: event density - instrument 1
  • DS 2: event density - instrument 2
  • DS 3: event density - instrument 3
  • DS 4: event density - instrument 4

Page 2:

  • NT 1: note number - instrument 1
  • NT 2: note number - instrument 2
  • NT 3: note number - instrument 3
  • NT 4: note number - instrument 4

Page 3:

  • ACNT: accent amount (larger number is more variation) - applies to all instruments
  • X : X amount for selected instrument
  • Y : Y amount for selected instrument
  • XAOS: chaos amount - applies to all instruments

Page 4 - Main Mode:

  • BPM: tempo

Page 4 - Instrument View Active:

  • NT -: note number for active instrument
  • M-CHAN: midi chanel for active instrument
  • BPM: tempo
