ProTrekkr (formerly known as NoiseTrekker by Juan Antonio Arguelles Rius aka
Arguru) is a tracker program combining a software synthesizer together with a
traditional samples tracker which can be used to create electronic music (like
psytrance, trance goa, hard acid, IDM, chip, techno, etc.) for small sized
intros, demos or games.

Installation:

Extract the archive somewhere on your harddrive.

Run ProTrekkr by doubleclicking on its icon.

Changes:

v2.0.1:

- Big tracker & replay speed up.
- Volume of instruments were left at 0 when loading waveforms.
- Added the possibility to only delete the current instrument split.
- Fixed an issue within .ptp saving function.

v2.0:

- Tempo can now go down to 20 BPM.
- 303 units entirely modified, now they should behave
  and sound a bit more like the one found in Propellerhead's Rebirth.
- Files & dirs entries are now sorted alphabetically.
- Input zones are now displayed with altered colors.
- 6 default color themes are now available.
- Range selection in sample editor speeded up.
- .mod import function is now much more accurate
  (note: it can also import FastTracker 1 .ft modules).
- Fixed a bug in samples looping (1 byte was always missing from the loop).
- Improved shadow patterns rendering.
- Patterns shading is also displayed for track which are turned off
  in the sequencer (shading can be turned on/off globally).
- Improved sample editor:
  - Speeded up (especially while selecting) and overall cleaner processing.
  - Middle mouse button can now be used to zoom in/out.
  - Added cut/copy/paste with 4 copy buffers.
  - Crop function (remove everything from a waveform but the selection).
  - Zap (delete a selected part of a waveform without copying it).
  - Select view / Select all.
  - Reverse (invert the selected part of a waveform).
  - Selection shifting.
- Added position jump effect (1F) (Can be combined with pattern break (0D)).
- Added fine volume slide up and down effects (20 & 21).
- Added fine pitch up and down effects (22 & 23).
- Speed can now go up to 32 ticks/beat.
- BPM weren't refreshed properly on screen when being changed inside patterns.
- Multi-notes channels weren't re-initialized properly when loading new modules
  which could lead to a crash.
- Instruments used without notes won't retrig the note but only change
  the waveform (like in the original protracker).
- Filelists won't be redrawn after a loading process
  and they won't jump back to the top after a saving one either.
- Fixed a bug in Pattern loop command (6).
- Splitted the play button into 2, 1st one to play song,
  2nd one to play pattern, right mouse button on those to play song
  or pattern from current row (using left mouse button starts from top row).
  Shortcuts:
    RCTRL: Play song from start of pattern.
    LSHIFT + RCTRL: Play song from current position.
    RALT: Play pattern from start of pattern.
    LSHIFT + RALT: Play pattern from current position.
- Added transposing capability to the instruments remapping function.
- Changed LCTRL+H & LCTRL+LSHIFT+H to LCTRL+K & LCTRL+LSHIFT+K.
- Default patterns zoom is now selectable.
- Effect 10 (Delay send) was inneffective when Track tab was selected.
- Overall better accuracy in replaying and volume ramping.
- Global volume of instruments weren't saved in .pti files.
- Using non existant instruments in patterns should now be handled properly.
- Converted some tunes from FastTracker 1 for test purposes.
- Instruments amplifications are now modulating synths only when necessary
  (meaning: only when the instruments are going through the synths).
- Volumes columns and effect 3 are now calculated differently
  and are cummulative:

    c-3  0 .. .. ........
  
  will play instrument 0 at it's former volume.

    c-3  0 20 .. ........
  
  will play instrument 0 at roughly 50% of it's volume.

    c-3  0 .. .. 0380....
  
  will play instrument 0 at roughly 25% of it's volume.

    c-3  0 20 .. 0380....
  
  will play instrument 0 at roughly 25% of it's volume.
- Fixed a bug in note retrig effect if no note was specified
  (now it takes the last played note as it should).
- Rewrote the latency handling routines in a more robust & precise way.
- Fixed the right mouse button caret horizontal scrolling.
- Added effect 24: turn flanger on/off.
- Salvaged 3 NoiseTrekker beta version modules,
  they really don't sound like in the original one as i had to rework them,
though.
- Real numbers of used patterns are now counted when saving a .ptk.
- Fixed a small issue with keyboard handling in message boxes.
- Added Moog Lo & Moog band filters for synth instruments.
- Fixed a bug in .ptp saving & replay: some instruments infos were scrambled.

v1.99e:

- Test release for Linux 64 bit.
- Linear interpolation can now be selected (beside none or cubic) it's faster
  than cubic and still gives better results than none.
- Fixed a clipping bug in samples loading (for both .wav and .aif/aifc).

v1.99d:

- Added support for Audio IFF files loading.
- Auto zooming of multi-notes tracks fixed
  (tracks are now properly being reduced to fit entirely on the screen).
- Added support for German keyboard layout.
- Fixed a signal overflow which occurred with 2nd 303 unit when 1st wasn't
active.

v1.99c:

- Slicer effect (4) now uses the current volume
  (from instrument's, column's or volume fx (3)).
- Better general handling of the volume column.
- Changed the behaviour of auto fading effects (17 & 18): playing a new note  
on a track which is currently auto fading won't stop the fading process   which
now have to be switched off by using either 1700 or 1800.
- Auto fading was kinda broken with multi notes tracks.

v1.99b:

- Long time running bug making text to disappear when using the 303 units
  should be (hopefully) gone now.
- Each track now have 2 columns of effects.

v1.99:

- Added maximum latency checking on OSX.
- Updated SDL library to latest for OSX and Windows.
- LCTRL+L/LCTRL+H: transpose a selected block to 1 octave lower/higher.
- LCTRL+LSHIFT+L/H: Transpose the note of a selected block
                    to 1 octave lower/higher but only for the currently
                    selected instrument.
- Added buttons for block commands.
- Commands with right mouse button functions are now shown
  with slightly different colors.
- Improved 303 editing by keeping current steps for each patterns/banks/units.

v1.98o:

- A value can now be specified with Reset Filter LFO FX (16).
- Randomize block command range is now 00 to ff on effects data columns.
- Fixed a bug occuring while using volumn columns and/or Set volume FX (03)
  with synth instruments.
- Editing was kinda broken when Step add was 0.
- Enabled latency control on Mac OSX.
- Re-enabled use of SDL threads for AROS.

v1.98n:

- Fixed a small issue with END key not jumping to proper pattern's end
  in some cases.
- Using F00 effect now stops a song.
- Fixed a crash in the replay of .ptp modules.

v1.98m:

- Modified the way envs to volumes work with null values.

v1.98l:

- Fixed a nasty bug in packing & depacking functions.
- Integrated the Amiga OS4 and AROS modifications into the repository.
