The pattern editor allows you to actually writes note for your music. It looks like this:
Each track is represented by 6 columns:
The note and instrument
"E-2" indicates a E note (or "mi" using the solfège notation) at the octave 2. A "#" replaces the "-" between the note and the octave for sharp note ("dièse").
"01" indicates that the instrument 1 is used. The instrument 0 does not exist. It is possible that a note is present without any instrument. It means that a legato is used: the instrument does not start again when encountered: only the note changes. To create a legato, add a new note, and delete the instrument.
Then come the 4 columns of effects. They are always composed of one lower-case letter indicating the type of the effect, and three digits maximum for its value. How many digits depends on the effect. For example, the Reset ("r") effect only accept one digit (0 here). The same for the volume effect ("v"). The pitch up ("u") however requires 3 digits.
Activated or not the "follow" mode. If activated, the pattern will scroll to follow the music being played.
Indicates how many lines will be jumped whenever a note is entered. This is handy to quickly write sequence of notes that are apart from each other.
This indicates on what column your cursor is. This is handy not to get lost! Also, it displays the instrument name when the cursor is over the instrument column, and gives a detailed definition of whatever effect is under the cursor.
Just like you can left/right-click on the Vu Meters to mute one or all the channels, left/right clicking on the green or red number of each track does the same.
Control R / Control Space Toggles the Record mode. Record must be ON for you to be able to modify any track!
Cursor Moves the cursor.
Space Plays the current line.
Insert / Delete Inserts empty cell or delete the one where the cursor is.
Backspace Empties the cell where the cursor is.
* Inserts a "RST" note, which means "stop".
Return Selects the instrument that is under the cursor.
Ctrl + Return Selects the instrument that is under the cursor and view it.
Shift / Ctrl + E Increases / decrease the Step (see above).
Shift / Ctrl + O Increases / decrease the octave.
Shift / Ctrl + I Increases / decrease the current instrument number.
