Feature Discussion

This page is to discuss possible future features along with some implementation details. Lengthy discussions will get moved to their own page.

• Revamped Control System
• Single-Deck Vinyl Control
• N-Deck Support
• Skinning Engine
• DVS mode
• Aubio (misnamed Beat Juggling)

• Looping
• Configurable Cue Behaviour
• Code Organization and Cleanup
• Library Rewrite Using SQLite

• Waveform Thread Refactor
• Play queue and Library Improvements Proposals
• SoundSource Refactor/Merge

Looking to contribute to Mixxx? Here are some projects we think could be done in a weekend, and would be a great introduction to the Mixxx codebase.

• “Loading” animation for the waveforms
• adjustable drag sensitivity on visual waveform view
  • also a way to change the direction (“scratching motion”)
• Visual 'track ending' indicator for visual waveform

All Wishlist bugs on Launchpad Blueprints on Launchpad

If you think of a feature that we need to implement at some time, jot it down here so you don't forget.

Some of these are copied over from the forums and the old wiki, so they may be done already or irrelevant.

• Track section marking with import/export support for DJ Notation (http://www.djnotation.org/)
  • Could also be used to mark loops?
  • Feature should be unobtrusive and it should be possible to disable the displaying temporarily
  • Since the markup will probably not be accurate (especially when using times out of DJ notation) the visualization should not imply it as 100% accurate, this also implies that these markers/sections will not really double as cue points
• Split cue/master headphone support - Done: Pre/Main knob ([Master] headMix MixxxControl)
• Effects panel integration with UI
• 'Online' BPM detection so that visual waveform beat marks can actually be accurate. - BpmDJ engine being considered
• M4A support - In progress
• hotkey support (maybe configurable?)
• Cheap mode (main out left, cue out right) so users can get started using mixxx without any extra soundcard.
• Effect plugins
• Live input (switchable input at first, maybe a delay/pitchable input later)
• OSC controlled backend Details from Old Wiki
• generic usb hid input support.
• some more physically modeled turntable styles, with concepts of inertia, slipmat vector, and motor drive. Details from Old Wiki
• Normalize to the waveform, track volume and output (over longer period in the master output)
• Channel gain to affect the waveform
• BPM sync lock like in virtual dj (keep tracks in sync)
• Play lock feature so that you can't change a track that is currently playing - Some MIDI scripts do this already
• A button to switch between the vinyl emulation & pitch independent time stretch (“Master Tempo” on CDJs, “Key lock” or “Key correction” on others)
• Adjustable key when key lock is active (as on the Numark CDX/HDX/X^2)
• Remain / played time display switch - Already in Preferences→Interface→Position display
  • Would be nice if this could be done by just clicking the time field and would not require opening the preferences
• Clipping light to stay on (dimmer?) after clipping, reset by clicking
• Add a single deck view optimized for track setup (as in setting cue points and loops, potentially beat grid markers once we get some concept of beats with the beat detection feature planned for 1.8.5/1.9)
