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.

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.
 2022-03-16 20:26:02 +01:00
Robbert van der Helm f18c92b3b4 Support parameter groups for CLAP 2022-03-16 17:15:33 +01:00
Robbert van der Helm ce85874340 Implement the CLAP tail extension 2022-03-15 22:28:26 +01:00
Robbert van der Helm 1e9fdeddfb Don't report supporting MIDI and expression events 
Since currently these would just get thrown out anyways.
 2022-03-15 22:18:37 +01:00
Robbert van der Helm 69e4bc9156 Implement the CLAP note ports extension 2022-03-15 22:16:50 +01:00
Robbert van der Helm f53f6829f0 Implement the CLAP event filter extension 2022-03-15 22:08:29 +01:00
Robbert van der Helm b95c833352 Don't handle CLAP modulation events 
This would require special handling. Modulation acts as an absolute
offset for the current parameter value, not as a relative adjustment to
that value.
 2022-03-15 21:26:11 +01:00
Robbert van der Helm 9232f8a51e Derive Debug and Clone for CLAP output events 2022-03-15 18:53:35 +01:00

Robbert van der Helm 6fe967f65e Implement parameter change notifications for CLAP 2022-03-13 18:30:21 +01:00
Robbert van der Helm 87e447ab25 Mention potential race condition in CLAP events 2022-03-11 14:33:43 +01:00
Robbert van der Helm f98ba70764 Comment on the CLAP gesture handling 2022-03-11 13:27:23 +01:00
Robbert van der Helm 7339e8e956 Include CLAP_EVENT_SHOULD_RECORD for gestures 
Apparently this is what you're supposed to do.

Robbert van der Helm 5d3527c5c2 Also implement sample accurate automation for VST3 2022-03-10 23:39:58 +01:00
Robbert van der Helm b41b4ef725 Implement sample accurate automation for CLAP 2022-03-10 20:14:42 +01:00
Robbert van der Helm b9412657c1 Fix allocation error from thread locals 2022-03-08 14:07:29 +01:00
Robbert van der Helm 37e1b9523b Optionally disallow allocations in reset function 2022-03-08 00:46:17 +01:00
Robbert van der Helm 70d3b5d557 Add a reset function to the plugin trait 
This is used as part of CLAP 0.19/0.20, and we can just always call it
after the initialize function to stay consistent for VST3 plugins.
 2022-03-08 00:35:55 +01:00
Robbert van der Helm 10ced981bd Remove todos about fixing skewed discrete ranges 
Because those have been removed.
 2022-03-08 00:27:25 +01:00
Robbert van der Helm 8ee380864c Update for CLAP 0.20 2022-03-08 00:21:51 +01:00
Robbert van der Helm 79ab0cd7ed Add the special win32-dpi-aware feature on Windows 2022-03-05 16:02:52 +01:00
Robbert van der Helm 9267a8371c Add DPI scaling support 
That hopefully works.
 2022-03-05 13:37:35 +01:00
Robbert van der Helm e2605c8cee Add transport information for VST3 and CLAP 
This is available through the process context.
 2022-03-04 15:05:00 +01:00
Robbert van der Helm 99f97978a9 Reorder ProcessContext methods 
When we'll add more things here the more common getters should come
first and less common operations like changing latency should come last.
 2022-03-04 13:22:58 +01:00
Robbert van der Helm 80457ac0f9 Fix doc links after prelude migration 2022-03-03 23:30:29 +01:00
Robbert van der Helm 4c0b07c578 💥 Move re-exports to a prelude module 
So you can import everything at once, because you're likely going to
need at least 90% of it anyways.
