PLAY is a statement that plays a tune defined by Music Macro Language (MML) STRINGs.
Syntax
- PLAY mmlString1$[, mmlString2$][, mmlString3$][, mmlString4$]
Parameters
- The mmlString1$, mmlString2$, mmlString3$, mmlString4$ can be any literal or variable STRING consisting of the following commands:
- Command string values are not case-sensitive and white spaces and ; are ignored. Use upper or lower case as desired.
- O n - Sets the current octave (from 0 to 6). Example: PLAY "O3"
- < - Down one octave (cannot be below zero). Example: PLAY "<<" 'goes down two octaves.
- > - Up one octave (cannot be above 6). Example: PLAY ">>" ' goes up two octaves.
- A, B, C, D, E, F or G are the notes in the current octave. The following suffixes can be used:
- + or # for a sharp note. Example: PLAY "C#"
- - for a flat note. Example: PLAY "C-"
- N n - Plays a note n by number(n can be between 0 to 84 in the 7 octaves, where 0 is a rest). Example: PLAY "N42"
- L n - Sets length of a note (n can be 1 to 64 where 1 is a whole note and 4 is a quarter of a note etc.). Example: PLAY "L4"
- MS - Each note plays 3/4 of length set by L (staccato)
- MN - Each note plays 7/8 of length set by L (normal)
- ML - Each note plays a full-length set by L (legato)
- R/P n - Specifies a rest/pause (1 - 64). P1 is a whole-note pause, P2 is a half-note pause, etc. (The pause is 1/n note in length.) Example: PLAY "P32"
- T n - Tempo sets the number of L4 quarter notes per minute (n can be 32 to 255 where 120 is the default). Example: PLAY "T180"
- . - period after a note plays 1½ times the note length determined by L * T.
- .. - two periods plays 1-3/4 times the note length determined by L * T.
- , - commas in QB64 stop play advancement to allow more than one note to be played simultaneously. Example: PLAY "C,E,G,"
- V n - Voice volume in QB64 only can be any volume from 0 (none) to 100 (full). The default level is 50 when n is not specified.
- V-/V+ - Decrement / Increment the voice volume in QB64-PE only.
- MF - Play music in the foreground (each note must be completed before another can start).
- MB - Play music in the background while program code execution continues (QB64 has no note buffer limits).
- X + VARPTR$(string-expression) - executes a command string variable. It must be used with variables!.
- W/@ n - Select waveform in QB64-PE only can be (1 for square (default), 2 for sawtooth, 3 for triangle, 4 for sine, 5 for white noise, 6 for pink noise, 7 for Brownian noise, 8 for LFSR noise, 9 for pulse or 10 for a waveform defined by the _WAVE statement.
- / n - Attack duration in QB64-PE only can be a percentage of note duration from 0 to 100.
- \ n - Decay duration in QB64-PE only can be a percentage of note duration from 0 to 100.
- ^ n - Sustain volume in QB64-PE only can be a percentage of the voice volume (V) from 0 to 100.
- _ n - Release duration in QB64-PE only can be a percentage of note duration from 0 to 100.
- Q n - Simple volume ramp in QB64-PE only can be a percentage of note duration from 0 to 100. This sets sustain (^) to 100, attack (/) to n, and release (_) to n.
- Y n - Parameters for the current waveform in QB64-PE only can be 0 to 100 for pulse waveform, clock rate for LFSR noise, or seed for other noise waveforms.
- S n - Pan position in QB64-PE only can be 0 (left-most) to 100 (right-most).
- S-/S+ - Moves the pan position left / right in QB64-PE only.
- Numeric values "n" listed above can also be fetched from numeric variables using "=" + VARPTR$(numeric_variable).
Availability
- The following features have been added in QB64-PE v3.8.0:
- Complete support for X + VARPTR$(string-expression).
- Support for @ and Q commands.
- The following features have been added in QB64-PE v4.0.0:
- Support for multi-voice MML playback. Advanced BASIC (for the IBM PCjr and Tandy 1000) multi-voice MML can now play in QB64-PE.
- Support for W, /, \, ^, _, Y, S, S-, S+, R, V-, and V+ commands.
- Support for 6, 7, 8, 9, and 10 (user-defined _WAVE) waveforms.
Examples
- Example 1
- Plays a sound with the volume and note varying from 0 to 50. The maximum note can only be 84.
PLAY "q0mll64" DO FOR x = 1 TO 50 a$ = a$ + "v" + LTRIM$(STR$(x)) + "n" + LTRIM$(STR$(x)) NEXT FOR x = 50 TO 1 STEP -1 a$ = a$ + "v" + LTRIM$(STR$(x)) + "n" + LTRIM$(STR$(x)) NEXT PLAY a$ a$ = "" LOOP UNTIL INKEY$ <> "" PLAY "v10l1c,l4egl2o5c,o4l4eg" |
- Example 2
- Plays "Frosty the snowman". The lyric printing is not delayed by PLAY in QB64.
CLS: PRINT "Frosty the Snow Man" FOR X = 1 TO 2 PRINT IF X = 1 THEN PRINT "Fros-ty the Snow man was a jolly happy soul," IF X = 2 THEN PRINT "Fros-ty the Snow man knew the sun was hot that day" PLAY "t140o2p4g2e4.f8g4o3c2o2b8o3c8d4c4o2b4a8g2."

PLAY "o2b8o3c8d4c4o2b4a8a8g8o3c4o2e8e4g8a8g4f4e4d4c2." IF X = 1 THEN PRINT "There must have been some magic in that old silk hat they found." IF X = 2 THEN PRINT "He led them down the streets of town right to the traffic cop." PLAY "c4a4a4o3c4c4o2b4a4g4e4f4a4g4f4e2."

PLAY "e8e8d4d4g4g4b4b4o3d4d8o2b8o3d4c4o2b4a4g4p4" IF X = 1 THEN PRINT "Oh, Fros-ty the Snow Man was a-live as he could be," IF X = 2 THEN PRINT "For, Fros-ty the Snow Man had to hur-ry on his way" PLAY "g2g2e4.f8g4o3c2o2b8o3c8d4c4o2b4a8g8g2." IF X = 1 THEN PRINT "and the chil-dren say he could laugh and play just the same as you and me." IF X = 2 THEN PRINT "but he waved good-bye say-in' Don't you cry, I'll be back a-gain some day." PLAY "o2b8o3c8d4c4o2b4a8a8g8o3c4o2e8e4g8a8g4f4e4d4c2.p4" NEXT X PRINT: PRINT "Thump-et-y thump thump, thump-et-y thump thump, look at Fros-ty go." PLAY "t180g8g8g4g4g4a8g8g4g4g4a4g4e4g4d1" PRINT "Thump-et-y thump thump, thump-et-y thump thump, ov-er the hills of snow." PLAY "t180g8g8g4g4g4a8g8g4g4g4g8g8g4a4b4o3c2c4p1" END |
