This is an update of version 1.0907 that was uploaded in the
biz/demo directory. It contains several enhancements and bugfixes.



DESCRIPTION
-----------

   PlayHD is a 16-bit audio harddisk-recording package, based on the AHI-system
   by Martin Blom. With PlayHD, you can do multitracking: play a number of
   samples directly from harddisk and simultaneously record another (stereo) track.
   Thanks to AHI, an increasing number of samplers/soundcards can be used with
   PlayHD without re-writing a single bit of code. Even the Amiga's own Paula chip
   can be used to play samples in a special 14-bit calibrated mode.
 



FEATURES OF PLAYHD:
-------------------

      - This version can now play up to a maximum of 20 samples at a time.
        The amount of samples you can actually play depends on:
           * Processor power: since all the mixing is done by the processor,
             more channels can be mixed at higher frequencies on faster
             processors.
           * Speed of your harddisk and harddisk-controller. SCSI is
             preferred.
           * Samplerate: the higher, the better quality, but more data has
             to be processed and loaded from the harddisk per second.
           * The AHI-mode you have selected. Is it a stereo mode, stereo++
             mode with panning, fast mode etcetera?
           * The kind of sampler used. Samplers that have their own sample
             buffers are heavily recommended.
             
      - A mixing desk provides you with realtime control over volume, panning
        and mute per channel. A master volume slider and a stereo master-
        volume indicator are present too.

      - Full mixer-automation based on event-list: channel faders, panning,
        mutes and master volume can be automated.

      - Full duplex playback and record: if your soundcard allows it, you can
        playback samples while recording.

      - Sample-editing with the usual features like cut,paste,copy,erase
        range. Direct to disk, not limited by memory.

      - Effects like Delay, Noise Gate, Chorus, Comp/Limiter, Amplifier,
        Frequency filters and FIR-filters can be applied.

      - MIDI synchronisation: by sending a MIDI start-command and a
        Song Position Pointer, you can synchronize audio with an external
        MIDI sequencer. You can also receive MIDI start-commands.

      - Supports mono and stereo 16-bit AIFF-samples.
      
      - Possibility to do HiFi non-realtime mixing to a new AIFF-file,
        thanks to AHI.
      
      - A Time Line Display provides you with an overview of the loaded
        samples and their durations. Samples can be moved along the timeline.
      
      - A Locator window enables you to set 4 cue-points.
      
      - A time-slider in the Tape Deck window allows for fast locating in
        the recording.
      
      - etc..
