Sometimes it’s just easier to draw melodies in a sequencer than it is to actually play the melody on a keyboard. Especially if your music is fast. Essentially what you will be doing is drawing a rhythmic pattern composed of note segments that can be organized within a scale. Most software sequencers have 2 dimensions: The horizontal, or time dimension, and the vertical, or pitch dimension. As the playhead progresses along from left to right, the notes that are drawn on the horizontal lines are played. The rest of this section will be divided into two parts, one for each dimension.
