Todos for 1.8.0

Things to do for v1.8.0

• Update sound file test script in src/test/soundFileFormats to include M4A file generation
• Test MP3/OGG/FLAC/WAVs of varying sample rates and report results here
• Add MIDI controller mappings from the forums to the branch.
• Test MIDI mappings for correct functionality for as many currently supported controllers as we can
• Update the Wikipedia entry
• Update user manual

Remaining blocker bugs for 1.8.0 final

Looping

• Complete the looping feature, merge to trunk.
• Update controller mappings with hot cue and looping controls
• SCS.3d - done
• BCD-3000
• Hercules MK2
• Hercules RMX
• M-Audio Xponent
• Numark Total Control
• Reloop Digital Jockey 2

M4A

• Solve packaging issues
• Solve Windows X64 libfaad2 dll building issues (embedded asm vs intrinsics) - may be able to split the assembly code into its own file and assemble that separately - Successfully worked around it by disabling the (5 lines (!) of) assembly code and using the supplied C/C++ code
• Fix SoundSourceM4A decoder issues

Misc

• Bundle libsndfile's trunk code into Mixxx for FLAC fixes? (Since there's no scheduled release date for the fixed libsndfile)
• Collect enhanced controller mappings from forum posts for wider testing
• Fix compilation on Windows x64 to correctly use SoundTouch optimizations (or not depending on optimize flag) - Sean
• Update user manual
• Can someone with some pull PLEASE tell C-Net to update their Mixxx download page?! 82 downloads a week for Mixxx 1.5.0.2 does not make us look good.
  • Adam took care of it
• Upload 1.8.0 final to C-Net and update our home page link there (still points to SF)
• Update our FreshMeat page

MIDI Sub-system tasks

Remaining tasks here are just polish and are not required for release.

• Move all PortMIDI calls to one thread (the script engines can not directly call send*Msg anymore.) See this.
• Save multiple device files correctly, deleting previous .midi.xml files in .mixxx/

    * Save the meta-data (<del>controller ID</del>, author, description, etc...)
      * First make a GUI object that lets the user modify the author and description
    * <del>Find a more appropriate place to save the files other than the MidiDeviceManager destructor</del> Now done (only) when OK is clicked in the prefs
    * <del>Need a way to keep track of duplicate devices so separate files can be saved: Have DlgPreferences::slotApply() call MidiDeviceManager::saveMappings() which does them all in one shot (and can thereby keep track of them)</del>
* <del>Load those files correctly</del>
    * <del>Load files for attached devices regardless of if they're activated or not.</del>
* Replace MidiCategory with MidiStatusByte permanently (see mididevice.cpp line 195.)
* MIDI Scripting: <del>Pass the <group> value from the XML to the script as an additional parameter (at the end of the list so existing scripts are not affected.)</del> - Done by Phil
* <del>Add MIDI script timers</del>
* <del>Implement alpha-beta smoothing filter in the Engine (currently in scratch.* functions in the common script file) with fixed-interval updates. (I.e. if no new data arrives in the interval, assume the control is stopped and feed that data to the smoothing function.)</del> - Done in the MidiScriptEngine for relative controls in 1.8.0
* GUI changes:
    * <del>Replace "Activate" button with an "Enabled" check box</del>
    * <del>Display enabled devices in the tree in bold text</del>
    * <del>Auto-change "Output" drop-down based on auto-selected output device in MidiDevice(Manager) when the device is enabled</del> - Albert
    * <del>Make "Output" drop-down take effect when changed</del> - not happening in 1.8. Output drop-down is disabled for now.
    * Persistent mapping preset drop-down (don't return to "..." unless Clear All is pressed. If the user tweaks the mapping, say "<custom>" or something.)
    * Also clear the list of MIDI scripts when Clear All is pressed
    * Do not commit changes to the MIDI mapping tables unless OK is pressed in the preferences window. (I.e. allow pressing the Cancel button or the X on the preferences window to restore the MIDI mappings to their previous states.)
