- for those not in the know, this series provides a way to
remove the temporal distortion introduced when using an
audio frame-based gui for music-locked objects.
In short, the gui uses an audio frame representation to move
objects. It displays the object using frame_at_beat(), quantizing
the time value to audio frames. This is fine until the user selects
that frame but expects it to be interpreted as a beat.
Thus beat_at_frame() would not produce the user-expected beat
(temporal quantization error of up to 0.5 audio samples).
This is one method of mapping audio time to music time accurately.
- use exact beats to determine frame position.
- see comments in tempo.cc for more.
- this hasn't been done for split yet, but dragging and
trimming are supported.
This moves MIDI channel filtering into a reusable class and moves filtering to
the source, rather than modifying the buffer afterwards. This is necessary so
that the playlist trackers reflect the emitted notes (and thus are able to stop
them in situations like mute).
As a perk, this is also faster because events are just dropped on read, rather
than pushed into a buffer then later removed (which is very slow).
Really hammering on mute or solo still seems to produce stuck notes
occasionally (perhaps related to multiple-on warnings). I am not yet sure why,
but occasional beats always.
preparation for further Summary and Number of visible
track count fixes.
* “Only Self”: don’t resize child-views (old default)
* “Total Height”: distribute height equally among
all visible child [automation] lanes
* “Height per Lane”: given height should be applied
to all sub-views.
Fixes bug #0006138. This solution does make the other label move when settings
are changed (presumably what the fixed width stuff was for), but I don't think
this is a big deal. Lesser of two evils, at least.
Fix several other cases where a single mouse click could cause several
(not nested) selection ops.
Fix missing selection memento for midi notes and midi commands.
Rename some variables.
Fix random style issues.
Unfortunately we store the state of models as simply model, so if there's ever
duplicate model names, we're somewhat screwed, but this makes the (previously
unmanageably huge) menu usable, while retaining the "model name as global
identifier" state unmodified.
Fix some inaccurate/misleading comments that led to said bug.
Gracefully handle the "impossible" case where we can't figure out a state ID
for an automation track, instead of crashing.
No functional changes in this one (for easier auditing), but towards having
round up/down only if necessary modes, rather than kludging around that
situation with a double round as we do currently.
This takes a VERY long time to do, so is probably a problem for defined devices
with a ton of channels and devices, too. Not sure what the smart thing to do
here is, though adding lanes really shouldn't be this slow in the first place.
