Hively Tracker is a tracker program based upon the AHX format created in the mid
'90s by Dexter and Pink of Abyss. The format was relatively popular, and many
songs were created and used in scene productions and games. AHX was designed to
create a very SID-like sound on the Amiga.

HivelyTracker can import and export modules and instruments in the AHX format,
but it also improves on AHX in several ways and therefore has its own instrument
and module formats.

HivelyTracker offers the following features over AHX:

* Multichannel (4 to 16 channels)
* Per-channel stereo panning
* Two commands per note instead of one
* Ring modulation
* A more feature rich editor

HivelyTracker was coded by Xeron/IRIS
GUI design and skins by Spot/Up Rough

Changes since 1.5:

- Right since 1.0, EDx was broken because of how i'd implimented the
  two effect columns. Fixed. All replayers and plugins will need
  updating :-/ Thanks to skope for pointing this out.
- Fixed validity check for Cxx command, which broke in the ht replayer
  because the parameter is signed. (fixes the sidvibes ahx file, which
  used invalid Cxx commands). Thanks to megacz for pointing it out.
- The replayer now strips the upper nibble of 4xx instrument commands
  from "THX\0" AHX modules. These modules are saved from older versions
  of AHX that didn't have filters, and so if the upper nibble is set
  it activated filtering which is wrong since the module was created
  in an editor that didn't have filters. The AHX editor also does this
  stripping, but AFAIK WinAHX and its derivatives never did.
