Robbert van der Helm 3d454bfc9c Don't process audio at all with invalid buffers
If the host does some kind of flush this way with num_samples > 0 but
without any outputs or with zero output channels then we should not try
to read from the now invalid pointers from the previous cycle.

Robbert van der Helm 566095802c Decouple state functions from CLAP/VST3 wrapper
This should also be usable with a plain `params` object, since we don't
need hashes in the standalone wrapper.

Robbert van der Helm a79099f573 Work around Bitwig VST3 note expressions bug
Bitwig will only send these note expression events if the plugin claims
to support at least one custom note expression type, and if it returns
`kResultOk` on `INoteExpressionController::get_note_expression_info()`
when the expression ID is equal to the note expression type (even though
these are out of range, since this index argument is supposed to be a
linear index from `0..count`).

Robbert van der Helm 33c2d8288b Don't warn on parameter hash overflow

Robbert van der Helm f0303fed4b Remove now unnecessary input events sort
This was added in anticipation of having to merge the parameter change
MIDI CC events into the events stream, but VST3 threw a curveball and
now we need to do the sorting one step earlier.

Robbert van der Helm 52d7b47a24 Improve block splitting transport information

recompute the bar positions and numbers.

Robbert van der Helm 1a8f81e4c0 Support MIDI CCs, aftertouch, pitch bend for VST3
This required rewriting the way events and parameter changes are handled
for VST3 by putting them all in a single sorted array, because we can
now no longer read directly from the host's events list because we also
need to mix these new generated MIDI CC events in with it.

Robbert van der Helm 9740246d0a Always sort VST3 note events in prep for CCs
So we won't forget to add this then. CC messages come from the parameter
change queues while regular note event messages come from another queue,
so they need to be merged into one sorted queue.

Robbert van der Helm 0b3a5cd297 Support all of the CLAP expression types
These aren't supported for VST3 yet, we'll need to register note
expression controllers for that.

Robbert van der Helm 1141616466 Replace ACCEPTS_MIDI bool with new enum
So we can gate future MIDI CC support behind an additional option since
this involves more work on the VST3 side.

Robbert van der Helm 8f359feadb Store velocity as a float
Instead of converting this to a 0-127 value. We may be throwing away
precision otherwise.

Robbert van der Helm 84bac0a47c Spool param rescan call to the GUI thread
Otherwise the CLAP example host std::terminates, and we can also reuse
the existing restart task for the VST3 wrapper.

Robbert van der Helm 083885a40c Rework Params trait API with Arc instead of Pin
This is a breaking change requiring a small change to plugin
implementations.

The reason why `Pin<&dyn Params>` was used was more as a hint to
indicate that the object must last for the plugin's lifetime, but `Pin`
doesn't enforce that. It also makes the APIs a lot more awkward.
Requiring the use of `Arc` fixes the following problems:

- When storing the params object in the wrapper, the `ParamPtr`s are
  guaranteed to be stable.
- This makes it possible to access the `Params` object without acquiring
  a lock on the plugin, this is very important for implementing
  plugin-side preset management.
- It enforces immutability on the `Params` object.
- And of course the API is much nicer without a bunch of unsafe code to
  work around Pin's limitations.

Robbert van der Helm f9db59f4bc Add a resize request callback to VST3 GuiContext
With some more work in baseview this can be used to resize windows from
the plugin.

Robbert van der Helm 8d71369b2e Rename .is_bypass() to .make_bypass()
Because just like `.bypass()` sounds like a getter, so does
`.is_bypass()`.
2022-03-27 03:45:06 +02:00
Robbert van der Helm 8090d0ae41 Add explicit bypass parameter handling
Plugins can mark a `BoolParam` with `.is_bypass()`. Hosts can then link
use that parameter directly in their own UI.
