PS3M ® 002.5ß / 30.6.94

Some words about PS3M:
This little thing could be just another program to play music. It wouldn't
even be the first one I have done. The only special thing is that it plays
S3M-modules. For those to whom that word says nothing, can be told that
they are the modules from all newer Future Crew demos (from Fishtro
onwards), compotunes and the three Journey musicdisks and Chaotic Mind from
Skaven. After the recent release of ScreamTracker 3.01 Beta more and
more modules are obviously coming from other musicians too, as it really
is the best tracker on the PC. As they use 1-32 channels (although "only"
16 digital channels and 9 AdLib-channels) and 8 octaves, a normal Amiga is
not capable to play them, right? Yes, until now.
From version 000.9 onwards also 6-8 channel FastTracker modules can be
played with PS3M (should I change the name?!?). Although you can play
4 channel ProTracker tunes, I think there are faster programs available
for that :)...
In version 002.5 came support for MultiTracker (MTM) modules and 1-32
channel Protracker-style modules (TakeTracker and FastTracker 2(?)).
!!NOTICE!!:
From version 002.0 onwards, PS3M has a config file! Use of it is
_recommended_!
Technical "information":
This player makes quite a big difference to those "normal" Amiga players as
it has to mix all those channels to, in this case two, normal channels.
This is the normal convention on the PC as for example normal SoundBlaster
only has one digital channel. The only hard part is to make it fast still
having a great sound quality. For those interested, this mixing routine is
not one of those lame ones like in Startrekker, Octamed, Oktalyzer and so
on. It has real volumes and periods for each channel unlike the former ones
that control the volume with hardware and have no independent volume
control for channels. It mixes the sound in 16 bits for maximum quality and
has a volume boosting option to make the sound louder and clearer with
multiple (8+) channels. From version 002.5 onwards also a special 14-bit
output mode is available. The actual mixing loop is highly optimized and
has only 6 instructions (is faster than the one with 5...) per byte. All
this makes it possible to play even 8 channel S3Ms with high mixing rates
and great quality. The better (faster) your machine is, the higher rates
you get. It is designed to use as little chip-ram as possible to fasten up
on machines with real fast-ram. The system is disabled for the playing to
get the maximum performance out of a normal A500. From 000.2 onwards,
system friendly option is included for those with AGA- or turbomachines and
even us poor mortals... On a normal A500 it jams your machine nearly
completely, so it isn't too useful for you. Still I use it quite a lot
with my A500, so it isn't too bad after all...
The blue bars at the bottom of the screen indicate that the player has
free time. This helps you to tune the maximum mixing rate for each tune
separately.
There has been some argue about whether the surround option is a real
Dolby Surround or not. Therefore: IT HAS NOTHING TO DO WITH THAT DOLBY
THING, it is made just to enchance the dull stereo sound by playing
the two buffers from left and right with full volume and vice versa with
half of the volume. Like this:
Channel 0 - Left buffer, full volume
Channel 1 - Right buffer, full volume
Channel 2 - Left buffer, half volume
Channel 3 - Right buffer, half volume
This should end that discussion. Thanks for the ones who contributed
with pertinent response.
BUT!!!!
As everything changes these days, also PS3M now has Real Surround-option.
It needs a little more processor power, but not that much I though. Also
extra 128 kB is needed for extra buffers. It enchances the sound nicely
with headphones and is nice also with normal speakers. And if you got the
Dolby Prologic decoder (lucky you!), you should get the effect quite
nicely...
Some commercial advertisement:
This PS3M-routine is also used in the following players, so if you are not
content with the user-interface, use these:
DASMP from DAS Design (from 3.0 onwards)
Hippopotamus Player from Hippopotamus Design (MUST for under 2.0
Kickstarts, we still do exist!)
DeliTracker II already has a S3M-DeliPlayer (Hi Peter!) and should
be available in near future.
Possibly in new SmartPlay (if you contact me)
Possibly in PowerMusic Pro (if I remember to send the source...)
Look out for The Player 6.1 as it will be even better than 6.0 (surprise!)
Coming out sooner or later...

Some revision history:
002.5ß / 15-30.6.1994
+ 14-bit output! Needs _Much_ power, but is hopefully worth it.
Special 020+ optimized version should be included in 002.6.
+ Multitracker (MTM) support!
+ TakeTracker and similar 1-32 channel Protracker-style module
support.
- Some fixes with S3M-quirks.
+ Replay version is now also shown in info window to help
comparision to other players using PS3M-play routine.
* Show sample names now shows 16 names instead of 20 on one page.
Don't worry about that ß, because this is real 002.5. It's beta just
because I hadn't the time to do some improvements to the mixing routines.
002.4 / 12.6.1994
+ Added show sample names option. Hi Icebeat!
- Fixed a bug when started from WB.
+ Added contact info text.
- Little fixes.
002.3 / 25.5.1994
* Some speed improvements for 020+ (uses more lword access).
No slow down on 000/010.
* Recalculated S3M period table for NTSC (was PAL) as ST3 uses
NTSC periods.
+ Little touches here and there (All error messages now start
with capital letter, etc. :)
- Fixes in command line parser. NOTICE: system friendly option
is now just -s with no extras. If not present, disable option
is used.
- No more crap if no config file present.
Thanks again Deadbeat!
002.2 / 9.-10.5.1994
(Four versions in three days... maybe I should give myself a break?
No new versions for a week, promise!)
+ REAL SURROUND!
- Hopefully fixed that >32 kHz bug (Yolk, tell me!)
002.1 / 8.5.1994
(Fast, eh Yolk?)
+ Final solution for the screen mode problem, CIA! So, now it
SHOULD work also with those modes. But who uses them anyway, PAL
and A500 rule :)
+ BTW, in Productivity mode you can get mixing rate up to 56 kHz!
Thus artificial 28 kHz limit changed to 56. Note: as said works
only in Productivity mode. (Yolk: You said something about
working also in double-PAL (double-NTSC too?))
002.0 / 8.5.1994
(Oops, another digit :-)
+ PS3M now has a CONFIG FILE! It resides in S: and is called
(surprise, surprise!) PS3M.config. Check it out for format
and options.
- Still little fixes.
- Channel detection routine had some _serious_ bugs. Fixed.
+ At last, error messages!
- Loading a non-existent file crashed the machine. Fixed.
001.1 / 7.5.1994
- Still more bug fixes in system routines.
+ Should work (at least better) under NTSC and Multiscan modes. (Hi
Yolk!)
001.0 / 5.5.1994
? Darn, slipped to the next digit :-)...
- Fixed a bug in my XPK-loader, should work better although I
haven't noticed the difference...
* Changed the priority to 4 to make it more usable with slower
machines in system friendly mode.
- Crashes with slow machines should be over! (or at least less...)
* Changed to colors (now HiP-compatible :-) in system killer mode!
Thanks to K-P Koljonen for these! (Hi again, sending coming
sometime in the future :)
- The module name wasn't shown if started from command line in
system friendly mode, fixed. Thanks Deadbeat!
- Fixed a potential bug in sample offset command.
- Now you don't have to click the stop gadget twice
000.9 / 24.04.1994
+ Added FastTracker 6-8 channel and 4 channel ProTracker replay!
? Should the name be changed? Opinions been accepted.
+ Added command line options to bypass the requesters. See usage
by typing PS3M ?
000.8 / 08.04.1994
+ Changed the mixing loops to use 6 instructions, which made them
faster (2 cycles/byte/channel on 68000). Thanks Peter Kunath!
- Some potantial bugs fixed.
000.7 / 22.03.1994
+ Added shortcuts for requesters
+ Added skipping of positions $ff, which are separators of
different songs in one module. Used in TMP.S3M.
000.6 / 19.03.1994
- Added range checking to sample offset.
- Implemented some bugs in STMIK. Now PANIC.S3M plays correctly.
000.5 / 08.03.1994
- Some "little" fixes in retrig note. Wonder if it worked at all...
000.4 / 25.02.1994
- Ooops, Vibrato+Volslide and Toneportamento+Volslide were the
wrong way around. Too much Protracker-experience?
000.3 / 24.02.1994
+ Support for other than 50 Hz screenmodes (was a bug really...)
+ Correct CurrentDir
? Crashes under system are probably due to too slow machine as on
A4000 this doesn't happen at all... Trying to fix it...
? Planning some support for other multichannel modules (MTM, 669,
FastTracker 6 and 8 channels, etc...) Infos about these modules
are appreciated...
000.2 / 10.02.1994
+ Added system friendly option!
- For some odd reason some tunes crash under system...
! BTW, my birthday is on the 17th!
000.1 / 09.02.1994
- Fixed a bug with volumeslide. Now Satellite One plays correctly.
- Auch! I had left some fast-mem-only hunks in the executable.
Fixed.
000.0 / 03.02.1994
! Inital release on public pressure...
