Robbert van der Helm a74d8264fb Support CLAP transport information events 
This will cause the buffer to be split when the transport information
changes.
 2022-05-05 17:23:46 +02:00
Robbert van der Helm 06c5e4b04a Make parameter modulation stick after automation 
This is how it's supposed to be implemented in CLAP.
 2022-05-02 15:46:57 +02:00
Robbert van der Helm 10ae8e1d05 Enable modulation for CLAP parameters 
Everything else has already been implemented, but this is kind of
important.
 2022-05-02 11:51:56 +02:00
Robbert van der Helm a4b251e5ef Support monophonic modulation for CLAP plugins 
This avoids the potential for state corruption caused by modulation and
modulation can be displayed differently on the GUI.
 2022-05-01 19:05:51 +02:00
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.
 2022-04-30 02:00:09 +02:00
Robbert van der Helm 6185909ddf Also safeguard against zero channel counts in CLAP 2022-04-27 17:06:19 +02:00
Robbert van der Helm dedbfebb71 Add todos about potential duplicate reset calls 2022-04-26 14:15:57 +02:00
Robbert van der Helm 4779991edf Also move reset() call to process start for CLAP 
So the behavior is consistent for CLAP and VST3.
 2022-04-26 14:14:12 +02:00
Robbert van der Helm 4ac0c40812 Reset last processing status for CLAP on start 
Just like we're doing in the VST3 wrapper.
 2022-04-26 14:10:00 +02:00
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.
 2022-04-24 19:46:07 +02:00
Robbert van der Helm 9acd312768 Parmaeters are not real, they can't hurt you 2022-04-24 19:46:07 +02:00
Robbert van der Helm 19d4b73039 Implement parameter changes for standalone target 
Changing parameters from an editor now works just like in the other
targets.
 2022-04-24 15:48:42 +02:00
Robbert van der Helm f838062d72 Don't use an Arc for the CLAP editor 2022-04-24 15:48:05 +02:00
Robbert van der Helm b88707769a Add a way to find out the current plugin API 2022-04-21 21:27:36 +02:00
Robbert van der Helm ad50852aeb Fix CLAP event output struct sizes 2022-04-11 20:53:25 +02:00
Robbert van der Helm 5e486ab3d9 Explicitly handle 0 channel IO 
Instead of treating it as a flush. This is needed for note effect
plugins.
 2022-04-11 20:46:51 +02:00
Robbert van der Helm 65d87f87ed Add a way to output note events 
This supports all note events supported by NIH-plug, and both CLAP and
VST3.
 2022-04-11 20:46:51 +02:00
Robbert van der Helm e4606918e7 Rename next_midi_event() to next_event() 2022-04-11 18:15:14 +02:00
Robbert van der Helm 84d91d8826 Update dependencies for CLAP 
The signature for this function was incorrect.
 2022-04-11 16:18:39 +02:00
Robbert van der Helm 5b5bbf19f7 Prefix all polyphonic expressions with Poly 
Makes it much more obvious that they're polyphonic at a glance.
 2022-04-11 15:57:27 +02:00
Robbert van der Helm 63ad2b2cb8 Parse redundant CLAP MIDI events just in case 2022-04-11 15:56:33 +02:00
Robbert van der Helm 33c2d8288b Don't warn on parameter hash overflow 
But do mention overflows in the duplicate parameter warning.
 2022-04-09 11:47:23 +02:00
Robbert van der Helm 52d7b47a24 Improve block splitting transport information 
Don't do any recomputations at the start of the buffer, and also
recompute the bar positions and numbers.
 2022-04-08 23:10:38 +02:00
Robbert van der Helm 24837d1552 Implement full MIDI support for CLAP 2022-04-07 23:28:31 +02:00
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.
 2022-04-07 21:17:31 +02:00
Robbert van der Helm b9a10455bb Add polyphonic aftertouch support 2022-04-07 20:55:31 +02:00
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.
 2022-04-07 20:27:37 +02:00
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.
 2022-04-07 20:12:30 +02:00
Robbert van der Helm 2af3f84416 Rename State to PluginState 
Now that it is part of the public API.
 2022-04-07 17:39:34 +02:00
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.
 2022-04-07 17:25:12 +02:00
Robbert van der Helm d0064f87d6 Add state saving and restoring through GuiContext 
While preventing any possible data races.
 2022-04-07 17:19:24 +02:00
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 b1c34146ee Get rid of automatically generated bypass params 
I thought these were mandatory in VST3, they are not.
 2022-04-06 13:34:32 +02:00
Robbert van der Helm a49393f863 Update for CLAP 0.24 2022-04-05 16:32:00 +02:00
Robbert van der Helm 7b9eff456c Update for new vizia resize patch 
This version uses a property on the context instead of events. This gets
rid of all of the problems and complexity of the previous
implementation.
 2022-03-29 00:02:11 +02:00
Robbert van der Helm c568e5d3be Don't wait for the request resize result 
We'll need to find a workaround for this, but this makes resizing in the
CLAP example host way too slow.
 2022-03-28 00:50:08 +02:00
Robbert van der Helm f3330aee86 Implement the resize request callback for CLAP 2022-03-27 23:11:04 +02:00
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.
 2022-03-27 19:23:43 +02:00
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 7f365d1113 Update dependencies 2022-03-25 21:04:48 +01:00
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.
 2022-03-23 17:42:48 +01:00
Robbert van der Helm 0cb26b5b4c Don't process audio for bypassed plugins 2022-03-23 15:49:34 +01:00
Robbert van der Helm c6a34a63c4 Hide non-automatable parameters 2022-03-23 13:52:23 +01:00
Robbert van der Helm e9983cf71c Use ParamFlags::NON_AUTOMATABLE in the wrappers 
Setting this will cause the parameter to be hidden from the host's
generic UI and automation lanes.
 2022-03-23 13:11:00 +01:00
Robbert van der Helm f084f14095 Refactor GUIs to use param's own default value 
This removes the need to pass a lot of these `ParamSetter`s and
`GuiContext`s around. We also don't need explicit events to reset a
parameter anymore since you can get this information from the parameter
itself.
 2022-03-21 13:11:36 +01:00
Robbert van der Helm c22e522629 Greatly simplify Params trait 
This now is a single vector with all of the information in the correct
order instead of the hashmaps and a vector. This avoids deduplication,
and it especially makes manual `Params` implementations a lot more
convenient since you can't mess up with mismatching IDs between the
methods.

To accommodate exactly this, the persistent fields methods also have a
default implementation and the trait has been marked as `unsafe` since
it's the programmer's responsibility to make sure these `ParamPtr`s will
remain valid.
 2022-03-20 13:05:02 +01:00
Robbert van der Helm b9d79771cc Use String instead of &'static str in Params 
This may hurt performance in generic UIs a bit, but it will allow you to
programatically generate custom Params implementations for repeated
Parameters structs.
 2022-03-20 02:14:18 +01:00
Robbert van der Helm ea30ba7ffb Initialize parameter fields earlier 
This seems a bit nicer than initializing them on the struct as empty and
then mutating the struct.
