Music/!Player/STmod-DOCS
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Background SoundTracker ModulePlayer v1.04 30-Aug-1990 17:23
-------------------------------------------------------------------------------
Coding & design by ALT_Man
This little module will play the specified Amiga-soundtracker module until
told to stop. It allocates space from the RMA to fit the module in so it's
best to be at the supervisor '*' prompt when you load tunes. Use *PM to load
the PlayerModule.
Start a tune going using: *PlayMod <modulename>
where <modulename> is the name of an Amiga soundtracker module. From version
1.00, automatic selection of 15 or 31 instrument format is performed.
Note: Using a *PlayMod while one tune is playing will cause the first tune
to be stopped and the second one loaded & started.
Stop a tune playing with: *PlayStop
Show information about a tune with: *PlayStatus
This shows song name (not filename!), 15/31 instrument format, tune length, and
module length.
Set channel separation with: *PlayStereo <0|1>
Where 0 is Archimedes channels (slight bias left/right so tunes can be heard
out of single-speaker archies) and 1 is Amiga channels (full left/right).
Sample rate is currently fixed at 29Khz per channel. Takes appx 25%-ish CPU time.
This is now supplied in a RISC OS-type application: the directory includes this
file, the 'PM' module, the programs 'playmoda' (plays 15 instrument modules,
commented source), and 'playmoda2' (plays 31 instrument modules).

Version 0.06 (first release version)
------------
Version 0.07
------------
- My address/contant numbers updated as we have moved!
Version 1.00
------------
- Now autoselects 15/31 instrument files. 32 instrument player source included.
Version 1.01
------------
- 32 instrument play now fixed!
Version 1.02
------------
- BIG problem with me not clearing top bit of picth incase it was used in 31
instrument tunes!
Version 1.03
------------
- Fixed now so it never (fingers crossed) loses notes, I was storing a word instead
of a byte in the 'newdata' bit (blush). PlayModA and PlayModA2 also updated with
this fix! The problem ONLY occurred if the buffer filling was interrupted by the
'intr' routine (ie new note data), ie this was is you were running the player
off interrupts. If you ran off VSYNC's (eg in main demo loop or whatever) then
it is fine. Still, it's fixed now!
- If you have problems with modules giving address exceptions: it is probably that
the player can't work out what format the file is in: if the player finds a
&78 (decimal 120, ascii 'x') at position &1D7 in the file it loads, it assumes it
is a 15 instrument file. If you have 15 instrument files without this byte,
load an editor (eg !Edit) and find byte &1D7 (decimal 471) using f5, and key
[copy] (to delete that character), and then [x] (must be lowercase, this is the
hex &78). Then the module will play just fine.
Version 1.04
------------
- Just got filetype allocation from Acorn. Official filetype for
soundtracker modules is now &cb6.
- Fixed problems with pitchbend on some tunes being a bit over-zealous and
pitchbending off the top of the pitch range!
- 31 instrument tunes now can access the top 16 instruments (at last!). I
was checking the wrong bit last time... oops! PlayModA2 fixed to
incorporate this change too.
- PlayStereo command added which allows you to set the stereo separation.
- A few bits fixed hopefully to stop spurious crashes (clear more variables
before restarting...)
