Select a sequencer by clicking on the sequencer's tab. You can draw notes on the playback sequencers using your mouse. The brightness of a note represents the note's MIDI velocity (which is usually the same thing as volume). Bright notes are louder. Dark notes are quieter.
To change the "color" (or note velocity) of your brush, click within the grayscale pallet on the left of the sequencers.
You may notice that when you draw notes on to a sequencer, the
set command is automatically entered on the command line interface. These commands are also stored in the "command history", which can later be useful when recording scripts. The
set command has the following syntax:
set [sequencer] [column] [row] [velocity]
You can set notes directly by typing the
set command on the command line interface.
For example, the following command will set a note with velocity of 120 at column 17, row 4 of sequencer p3:
set p3 17 4 120
Issuing a set command with a 0 velocity will remove a note complete from a sequencer:
set p3 17 4 0
