SHORT TUTORIEL.

Your "workroom".

In your terminal let’s go to MA-BASE.

Type:

cd "YOUR... /PATH... "/Drummer-s-Gigsaw/MA-BASE

Then type:

lilypond MY-SONG.ly

The file wasn’t empty. Indeed it’s a basic demo, the Demo-01 from

Le-Grenier. Have you checked if the compile was right in your terminal? Essential.

You are in your "workroom". Open the pdf

and listen to the midi file. Tsss! All seems too flat! And with odd

sounds sometimes.

Get the velocity values to the midi file.

In your console launch:

sh /home/....../Drummer-s-Gigsaw/MA-BASE/0-run-process-TOTAL-RECALL.sh

NOTE: After Lilypond’s compiles a GUI appears. For now double-clik on Exit

and answer by typing: n in your console.

Then look at MA-BASE. You’ve got two new midi file, including:

MY-SONG-TOTAL-RECALL+veloc.midi

This time it’s a midi file with a clearer sound and velocities on each note!

Enjoy it.

Transform the demo.

Now you want to transform the demo. OK.

In MA-BASE open MY-SONG.ly

For instance to copy a bar, put your cursor on the empty line just above

% DUMMY-BASE mes37.

Click and drag to the end of the bar (end of line with %| )

Put your cursor on the empty line just above

\tempo 4 = 110.

and paste 3 or 4 times your bar. Save your file.

If it’s not already done in your terminal let’s go to MA-BASE.

Then type:

lilypond MY-SONG.ly

Have you checked if the compile was right in your terminal? Essential.

If it’s not the case, don’t process further, it will be useless. Correct your

file. Help yourself with the messages at compile time, the pdf and the odd midi.

If you don’t succeed you’d better to read the Lilypond Documentation and

subscribe to its users mailing list.

This time you know the ritornello.

In your console launch:

sh /home/....../Drummer-s-Gigsaw/MA-BASE/0-run-process-TOTAL-RECALL.sh

Enjoy it.

Create your own song. Setup a new file.

Now you want to create your own song. OK.

Copy the blank file from Le-Grenier to MA-BASE. (First of all rename your old

MY-SONG, then rename MY-SONG-blank to MY-SONG. The file that you’re working on

always has to be named MY-SONG)

Import and arrange patterns

Go to the Bibliotheque , open Le-Puzzle-du-Batteur-DUMMY-BASE.ly

and pick-up new patterns of your choice from DUMMY-BASE to ... I stress pulse

"track" of MY-SONG.ly, not one another so far. (copy and paste) You can also

copy the comment

% DUMMY-BASE mes(num)

above your bar. So you would find it again inside a BASE. Sometimes usefull

when you want to add some ready-made variations of the same pattern later.

This time once again you know the ritornello.

In your console launch:

sh /home/....../Drummer-s-Gigsaw/MA-BASE/0-run-process-TOTAL-RECALL.sh

Transform patterns

Evidently you could transform the existing patterns in your file or delete

them. But BE CAREFULL with the Lilypond syntax. In all cases while you’re

playing in your "workroom" the console is your friend.

Don’t change ANYTHING outside your work area unless you know what you do!

Warnings at the top, middle and bottom of MY-SONG.ly reminds it to you.

You can rename the resulting MY-SONG-TOTAL-RECALL+veloc.midi file whatever you

want ONLY after the whole process.

P.S.: Besides this one, if you want to go further there is three files MY-SONG-Demo.ly in Le-Grenier.

Whereas Demo-01 only uses pulse "track", the only one where you could write

chords in which case all velocities are taking in account, (up to 47

simultaneous instruments!), Demo-02 uses Polyun, Polydeux et Polytrois "tracks".

You have to notice there aren’t chords in these 3 new tracks. Indeed in the

’G’igsaw Poly tracks are not processed in the same way than pulse track.

Thus chords generate wrong velocities, these famous "siameses" notes we are

talking about below. Associate a Poly track with a monophonic instrument

or a singer: only one note at a time. (No "siamese" song!)

Demo-03 uses one extra melodiques track which requires to write it with real

notes. See: How to use the melodic track. (advanced users)

Same remarks applies with regard to Poly tracks.

If you write different time signatures in each track the pdf output might

become faulty. Indeed Lilypond doesn’t break end of lines except if there are

synchronous each other. To avoid this issue you’ll find in Demos some tricks.

First of all try to uncomment (set-global-staff-size) at the beginning of

MY-SONG.ly. In Demo-02, when agogos in Polyun track enlarge their bars

(4/4 => 5/4 => 6/4 => 7/4...) I deliberately divided up the bars. So end of

lines are in sync and I get a more readable pdf.

Demo-04-GNU-socket is an example of patterns built with superpositions of

"nolets". It’s an independence challenge for a real drummer, isn’t?

Have fun!
