      After  first seeing this extension on AZ 2 (I think - it was a very
      early  issue)  I was very interested in obtaining the full version.
      Unfortunately  no  distributer details were included so I never got
      it...

      Anyway,   I  obtained  this  demo  version  and  gave  it  a  slam.
      Unfortunately the full version is only available from Australia and
      I  am far too lazy to sort out currency etc.  seeing as I never use
      Amos's music commands anyway.  But if anybody fancies it, contact :

      I have no idea if they're still around or anything so don't ask me!

      Installation  is  easy - it just copies straight over your original
      AmosPro_Music.lib  file and improves it beyond recognition - fixing
      the bugs in the original file and adding new features.
      @4Negative   point  number  one  -  When  you  select  'About  Loaded
      extensions'  from  the  Amos  menu, EME's entry is FAR too wide and
      goes off the screen.  It's purely aesthetic but it looks ugly.

      Once Amos is loaded, there is little to suggest there have been any
      changes until you try the new commands.

      As  well  as  a (bug fixed) Track Play, there is also a Track Pause
      and Track Cont command which are very useful.  Unfortunately, there
      seems  to  be  a  bug  in  the  Track Play command that crashes the
      computer  at  the end of a song unless you have previously used the
      Track loop Off command.  Nasty, and means that your music HAS to be
      looped  with Track loop now.  if you want a short tune, you'll have
      to stop it yourself!

      Commands  are  also  included  to  turn  off  Tracker  music  on  a
      particular  channel  so  you  can play sound samples over the top -
      essential  for  games  and  it saves you using .abk music.  You can
      finally set the volume of a Tracker module - at last it is possible
      to fade music smoothly in and out like in 'real' games!
      
      @4Some less useful commands that may be useful for Module players and
      the  like  are  TRNUMINST  which tells you how many instruments are
      used  in  a  Tracker module, TRLINE which tells you the position in
      the current block, TRPERIOD which returns the last note played on a
      specified channel and TRINST which names the last instrument played
      on a channel.

      Amos's  sample  looping problems have finally been solved - samples
      on one or more voices can be set to loop, and in this extension the
      command  really  works!   You can also change the speed of a sample
      'on  the  fly'  for smooth slides and give samples priority so your
      bullet sounds aren't drowned out by explosions, for example.
      @5
      The   MONITORSAMPLE   and  TAKESAMPLE  commands  really  make  this
      extension useful.  Yes - they provide direct sound sampler support.
      TAKESAMPLE   isn't   in  the  demo,  but  if  the  results  of  the
      MONITORSAMPLE  command  are  anything to go by it could be the best
      command  of ANY extension.  There again, it could be safer to write
      your  own  (if you know how - the relevant source was on a previous
      issue  of  AZ).   There  is no info on it's maximum sample rate.  I
      could  not produce an error with MONITORSAMPLE, even when I went up
      to  500,000  Hz  (CDs  are  recorded at 44,100 Hertz).  As a guess,
      based  on  my  machine's  prior performance, I'd say I got at least
      20,000  Hz  out of it (I sample most instruments at about that then
      downsample them so they take up less space).  Roughly, with the top
      sampling software and hardware, an A500 can sample at 29,000 Hz and
      an  A1200 (no fast RAM) at about 44,000 Hz.  Most mono samplers are
      rated  up  to  59,000  Hz  so  there's no danger of blowing up your
      sampler!   Stereo  sound  samples aren't supported (at elast in the
      Monitor  mode) which is just as well because they aren't much use -
      they take up twice as much RAM as mono samples, can only be sampled
      at  half  the  speed, use up two sound channels and sound damn near
      the same!

      All in all, this extension has some great commands, but many of the
      Tracker  commands  are  useless,  or available in craft (which just
      about everybody  has now) and it's real saving grace is the sampler
      support.  If you're writing a sampler prog and can't write your own
      routines to take samples, it may be worth checking out.
      @4
      Without  knowing  the price of this extension, I'd give it a rating
      of  7/10.   If  it is less than a tenner it'd get 8/10.   More than
      £15 and it'd get 6/10.

      Thanks  for the info Mike.  Strange that the Track Play command has
      had its bugs fixed only to be implemented with a new one!!!  Still,
      the extension may be of some use to games writers out there - check
      it out  and let us  know if anyone manages to get the full version.
