- >>>>> GCSound - 8SVX sample player
- ==========================================================
-
- GCSound is a 8SVX sample player which can be controlled
- from Gui4Cli (v3.6+) or from an ARexx program.
-
- You just run it, without any arguments (at the moment) and
- it will load itself, create a public message port named
- "gcsound" (note the lower case) and sit around waiting for
- Gui4Cli or ARexx messages.
-
- Many samples can be loaded and played at will. If the sample
- size is over 64k, it will be played directly from the hard
- drive. You can have as many samples as you want loaded (note
- that they will consume *chip* memory - maximum 64k each) and
- play up to 4 of them simuiltaneously.
-
- These are the commands it will understand :
-
- * LOAD <SampleFile> <Alias>
-
- Will load the sample into memory. <SampleFile> must be the
- full path and file name of the sample, and <Alias> is a name
- you give to it with which you can refer to it in other
- commands. This could be the plain file name for example.
- If the sample is over 64k, only the first 64k will be loaded.
- The rest will be read from disk when needed.
-
- ex:
- Address "gcsound"
- 'Load DH0:samples/mysample mysample'
-
- * PLAY <alias> [<times/0> <volume> <speed/-1>]
-
- This command will start to play an already loaded sample.
- <Alias> is the name you gave to the sample.
-
- You may also give the <times> you want it played (note 0 means
- - play forever), the <volume> (1-64) and the speed (125 - 1000
- or -1 for default speed). If you don't give these, the sample
- will be played forever, at it's default volume and speed.
-
- * UNLOAD <alias/"">
-
- Will unload a loaded sample, freeing it's memory. If it's
- playing, it will be aborted. If you do not give a sample name
- then *all* samples will be aborted and unloaded.
-
- * STOP <alias/"">
-
- Will stop the given sample, if it's playing. Again, if you do
- not give a sample name *all* samples currently playing will be
- stopped.
-
- * SOUND <SampleFile> [<times/0> <volume> <speed/-1>]
-
- This is like the Load and Play commands combined. It will
- load the given <SampleFile> (full path), play it and when
- finished, unload it.
-
- * VOLUME <alias> <1-64>
-
- With this you can change the volume of a loaded sample.
- This can also be done while the sample is being played.
-
- * SPEED <alias> <125-1000>
-
- Changes the speed of a loaded sample (while playing or not).
-
- * TIMES <alias> <times/0>
-
- Changes the times that a loaded sample will be played.
- Currently, this only works for large samples (i.e. the
- ones being played directly from the hard drive)
- Note that 0 means forever.
-
- * QUIT
-
- Will abort all samples playing, unload everything and
- quit.
-
- * INFO <alias>
-
- This command will return 2 numbers : the volume and the
- speed of the given sample. From Gui4Cli, this can be accessed
- through the $$Call.ret or $$RexxRet internal variables
- depending on whether you used Call or SendRexx.
-
- If sent from an actual ARexx program, they will be stored
- in arexx's RESULT variable.
-
- ==========================================================
-
- Behaviour :
-
- GCSound uses a user count system so that it may be accessed
- by many outside programs. When you start up the program, it
- will check if it's already running (i.e. if the gcsound port
- exists) and if it is it will send it a message to increase
- the users counter.
-
- When you send it a quit command, it will decrease the users
- counter and will *not* quit until all other programs using it
- it have also told it to quit.
-
- This means that for each time you run the program you must
- also send a respective quit command. You may get it stranded
- sometimes by running it too many times.. - just send it quit
- commands until you get a "host environment not found" error..
-
- Note :
-
- GCSound only plays mono samples at the moment. Stereo may
- be added later..
