Qtractor
![[Image: qtractor-screenshot10.png]](http://qtractor.sourceforge.net/image/qtractor-screenshot10.png)
Features
Multi-track audio and MIDI sequencing and recording.
Developed on pure Qt4 C++ application framework (no Qt3 nor KDE dependencies).
Uses JACK for audio and ALSA sequencer for MIDI as multimedia infrastructures.
Traditional multi-track tape recorder control paradigm.
Audio file formats support: OGG (via libvorbis), MP3 (via libmad, playback only), WAV, FLAC, AIFF and many, many more (via libsndfile).
Standard MIDI files support (format 0 and 1).
Non-destructive, non-linear editing.
Unlimited number of tracks per session/project.
Unlimited number of overlapping clips per track.
XML encoded session/project description files (SDI).
Point-and-click, multi-select, drag-and-drop interaction (drag, move, drop, cut, copy, paste, paste-repeat, delete, split, merge)
Unlimited undo/redo.
Built-in mixer and monitor controls.
Built-in connection patchbay control and persistence (a-la QjackCtl).
LADSPA, DSSI, native VSTi and LV2 plug-in support.
Unlimited number of plug-ins per track or bus.
Plug-in presets, programs and chunk/configurations support.
Unlimited audio effect send/return inserts per track or bus.
Loop-recording/takes.
Audio/MIDI clip fade-in/out (linear, quadratic, cubic).
Audio/MIDI clip gain/volume, normalize, export.
Audio/MIDI track and plugin parameter automation (dynamic curves, sample&hold, linear and spline modes).
Audio clip time-stretching (WSOLA-like or via librubberband), pitch-shifting (via librubberband) and seamless sample-rate conversion (via libsamplerate).
Audio/MIDI track export (mix-down, merge).
Audio/MIDI metronome bar/beat clicks.
Unlimited tempo/time-signature map.
Unlimited location/bar markers.
MIDI clip editor (matrix/piano roll).
MIDI instrument definitions (a-la Cakewalk™ (*.ins));
SoundFont (*.sf2) and MIDI Names XML (*.midnam) files also supported.
MIDI controller mapping/learn/assignment (mixer and plug-in parameters).
MIDI system exclusive (SysEx) setups.
JACK transport sync master/slave.
JACK session support.
NSM (Non session management) support.
MMC control surface enabled.
MIDI Song Position cueing support.

Re: Qtractor - linux - Bam - 10-10-2013
rncbc.org updates Qtractor (Linux) to v0.5.11
- Adding a track now inserts it after the current one, if any; one can also drag and move a track below the last one in the track list (main view left pane).
- Extended Edit/Select Mode/Automation: multi-selection mode, cut, copy, paste and delete of current track's automation curve nodes, now reached implementation ready status.
- Another old silent bug bites the dust: changing track names were dropping any track gain/volume and panning automation curves when saving the session.
- A primeval processing bug has been sorted out: aux-sends to audio output buses that just appear to be after the input bus where they're inserted were being left muted and silent (on a ticket follow-up by Holger Marzen, thanks).
- Fixed a sure crash bug exposed when processing of aux-send plugins when inserted too early on audio input buses chain (after a ticket report by Holger Marzen, thanks).
- Allow the build system to include an user specified CFLAGS (patch by Cristian Morales Vega, thanks).
- Shift/Ctrl keyboard modifiers now set to extend current clip selection while in main track view's Edit/Select Mode/Range, Rectangle modes.
- Main Edit/Select Mode/Automation icon retouched to look a bit more obvious and intuitive, hopefully
- Allow to change the velocities/values of the current selected events which have the exact same onset times and hide beyhond each other on the MIDI clip editor's pane below the main view piano-roll (ie. the one that represents MIDI event values as a bar chart).
- Fixed some problematic playback/export muting and annoying cleanup freezing, due on audio tracks with too many clips eg. more than hundred clip splits (hopefully fixes an issue reported by Louigi Verona, thanks).
- LV2 UI resize feature support/control added.
- Fixed dedicated MIDI control and MIDI metronome port connection restore conflict (thanks to jhammen catch & patch
.
- New user preference option added: reverse middle-button role to Shift/Ctrl keyboard state, in special regard to edit-head/tail vs. play-head positioning while on the main track and MIDI clip editor (aka. piano-roll) views.
