Play

[This article is a stub. You can help by filling it out.]

The #play [sound] command in ZZT-OOP allows objects and scrolls to play music and sound effects. (Note a scroll using #play does not suppress the default scroll sound effect.)

Sound Format

The general syntax is that parameters come before the notes and drums they modify. The octave and length parameters are reset each line. The default note length is 1 (32nd note), and the default octave is 3 (ranges from 1 to 6 inclusively).

Parameters

Symbol	Denotes	Length in Ticks
t	32nd Note	1
s	Sixteenth Note	2
i	Eighth Note	4
q	Quarter Note	8
h	Half Note	16
w	Whole Note	32
3	Triplet	(n/3)
.	Time-and-a-half	(n*3)/2
+	Up octave	N/A
-	Down octave	N/A

In order to work, the triplet and time-and-a-half modifiers need to be placed somewhere after the length parameters they are modifying (eg w3 or h.). Also, these parameters can stack on each other (eg w3. produces a 15-tick-long note length).

The triplet and time-and-a-half parameters use integer floor division. If the result of the division is 0 (with either t3 or s3), then the length value will underflow and ZZT will play a 256-tick-long notes (~25 seconds each).

Notes and Rests:

• X - Rest
• CDEFGAB - Piano notes, can be followed by:
  • # - Sharp
  • ! - Flat

Drums

Symbol	"Sound"
0	Tick
1	Tweet
2	Cowbell
3	N/A -- Denotes Triplet
4	Hi snare
5	Hi woodblock
6	Low snare
7	Low tom
8	Low woodblock
9	Bass drum

All other characters are silently ignored (like comments).
