Robbert van der Helm b2e6bd5515 Create a separate InitContext 
Only a couple of these functions would be needed during initialization.
In the next couple commits ProcessContext will get a way to access
auxiliary IO, so this really had to be separated.

Robbert van der Helm f4f54029eb Add a deactivation callback 
This is the equivalent of initialize()
 2022-05-24 13:05:06 +02:00
Robbert van der Helm 596b04af0a Add preliminary support for auxiliary IO 
The missing parts are allocating buffers for these busses, copying data
to those buffers, and adding methods to the ProcessContext to interact
with these inputs and outputs.

Robbert van der Helm 937842d2c5 Suggest copying {Bus,Buffer}Config as needed 2022-05-22 13:39:19 +02:00
Robbert van der Helm 783dc2245e Store the processing mode in BufferConfig 
Instead of having a function on ProcessContext.

Robbert van der Helm bb3175f68e Return -> Returns at the start of a docstring 
The imperative tense doesn't make any sense when the function is a mere
getter and doesn't actually perform a nontrivial task.

Robbert van der Helm cf3745a4e1 Somewhat clarify initialize_block_smoothers() 
This function is meant to be called by the plugin itself, it only lives
in the plugin trait to make using it more convenient.
 2022-04-24 15:48:05 +02:00
Robbert van der Helm f3db4a9ed0 Add a (not yet functional) standalone exporter 2022-04-24 15:48:05 +02:00

This should use the constants.

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 1f8db9d9c2 Mention NoteEvents being zero indexed 2022-04-11 19:48:07 +02:00
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.
 2022-04-08 20:53:32 +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 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 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 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 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.

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.

features.
