No more pickle.
About 15% faster for small messages, but (surprisingly) slower for large messages...

Ben Niemann 79b35d9689 Merge changes for the 'command cleanup' sprint.
- Use a common Create/Update/Delete convention for naming commands.
- Simplify the API of the Command class.
- Add factory functions for the remaining commands in noisicaa.music.
- Rename node related stuff:
  - 'pipeline graph node' -> 'node'
  - 'pipeline graph connection' -> 'node connection'
  - 'pipeline graph' -> 'graph'

Ben Niemann f4ce7f53d2 Rewrite MIDI input.
- A new "MIDI source" node, which can feed MIDI events from any ALSA device into the graph.
- All done rt safe in C++. The older Python implementation in noisicaa.devices has been removed.
- Still quite hacky:
  - It's built into the portaudio backend. There should probably be a separate "ALSA sequencer"
    backend for this, with the option to have an alternative "Jack MIDI" backend. But for that I
    have to figure out how to have separate backends for audio and MIDI and how that interacts
    for all possible combinations.
  - It just blindly connects to all readable MIDI ports, collecting all events. Filtering out
    the events for a specific port (e.g. a MIDI keyboard) happens in the "MIDI source" node.
    The engine should track, which ports are being used and only connect to those.

Squashed commit of the following:

    Not needed after all.

    Wire up MIDI source to events from the backend.

    - Make the event buffer accessible via the block context.
    - Backend creates sequence of (uri, midi) tuples.
    - ProcessorMidiSource filters that list and emit list of midi events.

    Make the main ALSA sequences listen to all output ports again.

    Now also tracking new ports as they appear.

    Editor tracks devices in a QAbstractItemModel.

    And MIDI Source node uses that for the port selector combobox.

    Device manager that tracks ALSA sequencer clients.

    - Allow backends to post engine notifications.
    - PortAudioBackend runs a separate (non-rt) thread, with a sequencer client just for listening for
      client notifications.
    - Create a DeviceDescription proto for ALSA sequencer clients and post them as engine notifications.

    A MIDI source node, which doesn't really do anything yet.

Author: Ben Niemann <pink@odahoda.de>

    Use C string for Spec::get_buffer_idx() to avoid malloc in the audio thread.

commit 24cfffdf60a4ad888e65fe839165666ebef0f9f0
Author: Ben Niemann <pink@odahoda.de>
Date:   Sat Jan 12 08:13:26 2019 +0100

    Add a "System In" node to the graph and wire it up to the MIDI events from the backend.

    Also rename "Audio Out" to "System Out", because that makes more sense, now that there is more than
    audio being passed around.

Author: Ben Niemann <pink@odahoda.de>

    Add Backend::input() method to read incoming MIDI events.

    Also switch to an enum for the channel arg.

Author: Ben Niemann <pink@odahoda.de>
Date:   Sat Jan 12 08:08:20 2019 +0100

    PortAudioBackend also reads MIDI events into a buffer.

    Very prototypish implementation. It just scans for all available devices and connects to their
    outputs. Still need to think about how to deal with different devices.

Ben Niemann 2a23e927b5 Upgraded mypy-protobuf.
It now knows about extension fields, so I could remove a bunch of 'type: ignore' pragmas.
2019-01-09 06:33:12 +01:00
Ben Niemann 21ec283822 Reorganize code to make creating new node types easier.
Adding new node types required adding bits and pieces in many places, which was tedious and failure
prone.
Now it's just cloning the directory of one of the existing nodes and adding a few lines to
'registries' (all in one directory).

Also:
- Reanimate custom csound node.
- All nodes can be muted.
2019-01-08 10:11:57 +01:00

Ben Niemann 45f67ea7f6 Make the audio thread (mostly) realtime safe.
- Purge all remaining Python from the critical path.
- Add a "realtime checker", and use it to remove most uses of malloc in the audio thread.
- Make logging from the audio thread realtime safe.
- Add a tool to profile the audio thread.
- Set realtime priority on the audio thread.

Ben Niemann bc8cc6bf71 Upgrade mypy to V0.650
- fix a number of newly reported issues with PyQt5 stubs.
- add empty stub files for all 3rdparty libs without stubs.

Ben Niemann 98328ca0fd Upgrade pylint to V2.2.2

2018-12-21 19:12:26 +01:00
Ben Niemann 66d7f8c6af Change the primary metaphor to 'modular synth' instead of 'multitrack recorder'.
- tracks are now just special types of nodes in the pipeline graph.
- completely reimplemented the pipeline graph UI.
- greatly simplified the UI, got rid of all the docks.
- some functionality got lost along the way or hasn't been reimplemented yet.

Ben Niemann c2e36770c6 MockApp for UI tests just implements AbstractEditorApp. 2018-06-03 19:50:03 +02:00
Ben Niemann 42886ac2a9 EditorApp does not subclass QApplication.
Instead QApplication is created separately and EditorApp just holds a reference to it.
Merged BaseEditorApp and EditorApp into one class.
2018-06-03 16:51:41 +02:00
Ben Niemann 4c237f8ea6 Improve typing of ui_base.

Ben Niemann 49cb41c646 Use typesafe callbacks.
Replace untyped CallbackRegistry by:
- explicitly declared Callback objects for each target.
- CallbackMap for maps of uniform callbacks.

Changed noisicaa.ui to use the same signature for callbacks.
Moved common code for synthetic attributes (e.g. project.duration) up into noisicaa.model.
2018-06-03 13:53:29 +02:00
Ben Niemann e60d6a11d0 Major refactoring of the project model.
- Move basic model code into noisicaa.model.
- Change internal property storage to protobufs.
- Commands also use protobufs.
- All serializations uses protobufs.
- Object are managed by a Pool object.
- Object references are stored as object IDs and dereferenced lazily.

Also:
- Everything is pylint clean.
- noisicaa.music and most of noisicaa.ui are now mypy strict.
- Generate mypy stubs for generated protobuf code.
- Cleaned up some obsolete cruft.
- Some improvements to runtests.
2018-05-26 14:58:16 +02:00
Ben Niemann 1007c3968d Some more mypy strictness for noisicaa.music.
But I'm hitting some design issues, which make this exercise quite cumbersome. Some more refactoring
is needed to make the code structure work better with type annotations.

Ben Niemann b7748dfa2a Replace **self.context_args by context=self.context.
Equivalent, because context_args only contained one 'context' entry anyway.
And the old form confused mypy a bit.
