Session handles the case when the button is used to enable cue triggering, by
forcing a locate to the current transport position.
TriggerBox now connects to the correct configuration object to notice when cue
triggering is disabled, and sets _cancel_locate_armed appropriately.
this solves the oft-recurring problem where we assign
a beat-count of '3' or '7' because minipm mis-detected the tempo,
and that situation is vanishingly rare. it's better to assume 4 or 8
the user always has the option to change the number of beats (and
therefore the detected tempo) manually, for those clips that are
in a different time signature. but minibpm cannot be expected
to help us there.
NOTE: this is a fallback to make things 'just work' lacking any other context.
* if the tempo is detected in the filename, we use that instead
* clips that were recorded to the timeline use that bpm+timesig
* in the future we can use file-metadata (acidized wave?) instead
* this is audio-only: midi files can have an embedded timesignature
but... given no other information, experience says the vast majority
of downloaded/purchased clips will be 1,2 or 4 bars at 4/4.
bugfix: changing the FA state can overwrite the clip's name and color
Some params (like gain) can and should take effect immediately
by directly setting the properties. TRIGGER_DIRECT_SET does that.
But we still, ALSO have to set the ui_state, because when the
triggerbox imports ui_state via update_properties() it will
overwrite your changes.
Said another way: since we use a queued ui_state to set the properties,
you ALWAYS have to set and use the ui_state mechanism, even if you want
to short-circuit the process for specific properties.
Having identified the trigger that will be running at a given transport position, we determine its effective
length (not necessarily its own length) and last start, then "jump" forward to the next-earliest start
point prior to the transport position. This greatly reduces the amount of actual audio processing we
need to do to prepare the trigger to run in sync at the transport position.
This commit also adjusts the targetted transport position by the processor's playback offset, so that
it is correctly prepared to run() once the transport starts again.
Logic errors when using cue-isolated or empty triggers were also fixed.
This does the internal shutdown of a Trigger that is shared between
a normal shutdown and when stopping for a locate/stop. There's no
output to buffers possible.
This method/design may need to change if/when we add declicking for
various conditions
* audio files can be named "0bpm" to make them un-stretchable
* however they still need a sensible beatcnt, and therefore tempo
* assume tempo 120bpm and assign a beatcnt based on the file's length
* the user might later enable stretch, and we need to be sensible about it
* intercept {pgm|bank}-change messages, and replace them with triggerbox values
* check is_set() extensively; we have arrays of pgms but most are unused
* initialize patches to GM standard (drums on 10) in case file has none
* in the case where file had none, check the Auditioner to see if user set any
* in the case where a file has patches, use those instead
* also stash the UsedChannels so we can show only the used chans in the UI
At some point during code refactoring, we ended up setting up the 3 transition times, intedned
to define when the *previous* transition occured, as we checked to see if a transition
would occur during this ::run() call. This led to (in particular) MIDI clips ending early,
because the transition_beats value was set to the *next* (upcoming) transition, and we used
this to define the timeline position of MIDI events
This allows for a different quantization to be used when WaitingToSwitch,
used when we explicitly start a different Trigger. When "just stopping"
we continue to use 1 bar quantization; when switching to a different
Trigger we use the quantization of the next Trigger
A trigger can be in a playout state when we decide to change its
state to WaitingToStop (e.g. due to a cue marker). This design
leaves the playout condition "in effect" despite the state changing.
