MIDI Pattern Sequencer

A classic MIDI pattern sequencer. On the left of the sequencer, there is the actual note of the lane with a corresponding number. Each step correspond to a measure. If the step is activated (yellow), the note will be played.

The note corresponding to each lane can be changed by clicking on it and dragging.

This process can have multiple distinct patterns which can be switched.

Channel

On which MIDI channel the output goes.

Current Pattern

The index of the current pattern.

Lanes

Each lane corresponds to one MIDI note.

Step

How many steps there are in a pattern. The minimal amount of steps is 4 and the maximum is 32.

Rate

To which musical declination corresponds a step: quarter note, 16th note, etc.

Workflow tips

Start simple: Begin with basic 4-step patterns before experimenting with complex polyrhythms.

Think in layers: Build patterns one drum sound at a time rather than trying to program everything at once.

Use standard drum maps: Stick to General MIDI drum note numbers for compatibility with most drum software and hardware.

Test timing: Verify that your patterns align correctly with the musical timing before building complex arrangements.
