ProTracker 2 clone v1.87

Remove all "v2.3D"-specific text in the GUI (this was misleading...)

ProTracker 2 clone v1.86

• The "BACKWD" funtion in Edit Op. #3 was broken if used on a marked section
• Fixed: Editing the song pos ("POS") value by clicking on its digits had a bug where the new value wouldn't be applied correctly.
• Small tweak of low-pass filter function used for Amiga filters

ProTracker 2 clone v1.85

• The Karplus-Strong (E8x) effect is now disabled by default, and its "DISABLE_E8X" protracker.ini setting has been replaced with "ENABLE_E8X" (for more info on this, read "ENABLE_E8X" comment in protracker.ini)
• Fixed a Karplus-Strong (E8x) effect bug (big whoop!)
• Removed ugly hack for removing "F00" commands if more of 7 of them were detected during .MOD loading. This breaks "dirt.mod" again, but I came to the conclusion that it was a bad hack anyway.
• Updated protracker.ini

ProTracker 2 clone v1.84

Small tweak of the 2x downsampler used in both the tracker audio and sample loader.
Technical details: Algorithm used has been changed from sinc w/ Kaiser-Bessel to Remez.

ProTracker 2 clone v1.83

• Audio quality has been improved for slightly better sharpness and fidelity.
  Technical details: The PT2 clone renders at twice the frequency (2x oversampling) for more BLEP/filter nyquist headroom, and then downsamples back to the original audio output rate. The 2x decimation halfband FIR filter used for this has been improved from 19 taps to 59 taps, to reduce the quality loss in the downsampling process.
  CPU usage will go slightly up, but it shouldn't be an issue on modern computers.
• The "2x downsample" option when loading samples now results in less treble loss. Same reason as above; increased number of taps (better filter).
• Fixed: There could be a click present at the end of a loaded sample if the original sample length was odd (uneven)
• Use miniflac for loading .FLAC samples (instead of libFLAC)

ProTracker 2 clone v1.82

• Fixed: The 2x downsample option during sample load caused a sample phase delay
• Fixed: Sample loops would sometimes not be loaded correctly for .WAV samples
• Fixed: When loading stereo samples (which would be mixed to mono), there could sometimes be a click present at the very end of the sample
• The song playback timer now wraps around to 00:00 after reaching 99:59 + 1
• Code cleanup

ProTracker 2 clone v1.81

• When clicking on the program while it was not in focus, let the mouse click be handled if an ask box dialog is shown. Fixes having to click twice on an ask dialog button after dropping a file onto the program.

ProTracker 2 clone v1.80

Fixed Amiga audio filter error in v1.79 (pi instead of 2pi in calculation)

ProTracker 2 clone v1.79

• Fixed loading of WAV samples of the WAVE_FORMAT_EXTENSIBLE type
• Fixed some small issues with the sampling feature
• Removed unnecessary custom math functions in the source code

ProTracker 2 clone v1.78

When loading .IFF samples, always set volume to max (64) instead of reading the sample volume from the IFF header.
This is because many IFFs used different ranges for the sample volume, so the resulting sample volume value would often be zero instead of max.
