Sequencer Programming Techniques

When programming a sequencer, you’re essentially creating the backbone of your musical piece, whether it’s a melody, bassline, or complex drum pattern.

It’s a process of assigning musical notes and rhythms to steps in a sequence, which can then be played back to generate sound through software or hardware instruments.

Programming Notes and Rhythms:

  • Start by selecting the length of your sequence, which can be determined by the number of steps, such as 16 for a single measure in common time.
  • Input notes by selecting the desired pitch and placing it on the corresponding step. This is where your melody and harmonies take shape.

Creating Basslines and Drum Patterns:

  • For basslines, focus on the root notes of your chords and rhythmically sync them with your drum patterns.
  • Craft drum patterns by placing kicks, snares, hi-hats, etc., on different steps to create a groove.

Adjusting Velocity and Timing:

  • Alter velocity to give notes a softer or harder emphasis, effectively varying their dynamic.
  • Apply swing to shift the timing of certain steps, adding a humanized, off-the-grid feel to your sequence.

Automation and Editing:

  • Use automation to change parameters like filter cutoff or effect levels over time.
  • Don’t hesitate to continually edit your sequence, experimenting with different patterns and grooves.

Working with Hardware and Software:
