Description:
 Qtractor is an audio/MIDI multi-track sequencer
application written in C++ with the Qt4 framework.
Target platform is Linux, where the Jack Audio
Connection Kit (JACK) for audio and the Advanced
Linux Sound Architecture (ALSA) for MIDI are the
main infrastructures to evolve as a
fairly-featured Linux desktop audio workstation
GUI, specially dedicated to the personal
home-studio.

Changelog:
 0.4.0  2009-03-13  The Foxy Dryad

- MIDI (re)connections fix; now caring for the
ALSA client and port textual names only, avoiding
as much as possible, any reliance on those
volatile client and port numbers.
- Transport/Backward and Forward commands may now
reset to immediate full start or end of session
locations, by just pressing the Shift or Ctrl
keyboard modifiers and clicking their respective
toolbar buttons.
- Default session/MIDI resolution has been set to
960 ticks per beat (960 TPQN, where a beat equals
a quarter-note); it is worth of note that the
previous default resolution was set to one order
of maginute lower, ie. 96 TPQN ;).
- Making (dis)connections now also flags session
as dirty.
- Internal Audio/MIDI engines queue/time drift
correction takes a brand new approach, specially
adapted to rolling tempo/time-siganture changes.
- MIDI monitor refresh-cycle slight internal
optimization.
- Converted obsolete QMessageBox forms to standard
buttons.
- Transport/Rewind and Fast-forward commands may
now be set to double-speed, by pressing the Shift
or Ctrl modifiers while clicking their respective
tool buttons.
- MIDI clip editor zoom ratios are now saved and
preserved across sessions.
- Time-signature is now directly accessible from
the main tempo spin-box which also reflects
current tempo status.
- Time/frame spin-boxes now allow to step change
each field individually, depending on the cursor
beam position.
- Make sure that Transport/Follow playhead option
is only effective when playback is actually
rolling.
- Primordial attempt to include MIDI Song Position
Pointer (SPP), Song Start, Stop and Continue
sequencing support.
- A completely new time-scale infrastructure is
now in place, with full support for session tempo
and time-signature map; this long due feature is
primarily accessible through the main menu,
View/Tempo Map...; also by double-clicking on the
the main window and MIDI clip editor time rulers
and left-clicking on the main toolbar
tempo/signature spin-box.
- Moving and resizing individual clips now cares
for track proper ordering and overlapping changes,
avoiding nasty out of sequence clips and other
unpredictable effects.
- An expedite MIDI clip quantize command is now
available from the main track view menu
(Edit/Clip/Quantize), which simply applies the
current snap-to-beat setting to a MIDI clip range
selection.
- Fixed that hideous bug affecting overlapped
audio clips when playhead gets moved backward,
causing the playback of those audio clips in
particular, go out of sync.
- Tracks are now limited to their minimum height,
specially effective in face of vertical zooming.
- Zoom mode option introduced (on menu
View/Zoom/Horizontal, Vertical, All).
- Tempo beat type is a new session property;
however it is not yet user modifiable and
currently disabled to default MIDI quarter note
(1/4).
- All open MIDI clip editor time-scales are now
updated and corrected when the main session time
base changes (tempo, time-signature, resolution,
etc.)
- MIDI metronome fixed, preventing duplicate click
events.
- MP3 audio file decoding was broken for way too
long and falling short for every file with custom
frames, ID3 tags and comments. Got shamefully
fixed.
- Time signature denominator (ie. beat divisor) is
now an accessible and effective session property.
- Attempt to retain original size (clip length) of
all audio clips when changing the global session
tempo and automatic time-stretching is not an
option.
