WineASIO provides an ASIO to JACK driver for WINE.
ASIO is the most common Windows low-latency driver, so is commonly used in audio workstation programs.

You can, for example, use with FLStudio under GNU/Linux systems (together with JACK).

For best results with Debian-based distributions, enable the KXStudio repositories and install WineASIO from there.

Do the following to build for 32-bit Wine.

make 32

Do the following to build for 64-bit Wine.

make 64

To install 32-bit WineASIO (substitute with the path to the 32-bit wine libs for your distro).

sudo cp build32/wineasio32.dll /usr/lib/i386-linux-gnu/wine/i386-windows/
sudo cp build32/wineasio32.dll.so /usr/lib/i386-linux-gnu/wine/i386-unix/

To install 64bit WineASIO (substitute with the path to the 64-bit wine libs for your distro).

sudo cp build64/wineasio64.dll /usr/lib/x86_64-linux-gnu/wine/x86_64-windows/
sudo cp build64/wineasio64.dll.so /usr/lib/x86_64-linux-gnu/wine/x86_64-unix/

NOTE:
Wine does not have consistent paths between different Linux distributions, these paths are only a hint and likely not what will work for you.
New versions of wine might also need to use wineasio64.so as name instead of wineasio64.dll.so.
It is up to the packager to figure out what works for the Wine version used on their specific distro.

For user convenience a wineasio-register script is included in this repo, if you are packaging WineASIO consider installing it as part of WineASIO.

Additionally a control panel GUI is provided in this repository's gui subdir, which requires PyQt5 to build and run.
The WineASIO driver will use this GUI as the ASIO control panel.

After building and installing WineASIO, we still need to register it on each Wine prefix.
For your convenience a script is provided on this repository, so you can simply run:

wineasio-register

to activate WineASIO for the current Wine prefix.

The wineasio-register script will register the WineASIO driver in the default Wine prefix ~/.wine.
You can specify another prefix like so:

env WINEPREFIX=~/asioapp wineasio-register

ASIO apps get notified if the jack buffersize changes.

WineASIO can slave to the jack transport.

WineASIO can change jack's buffersize if so desired. Must be enabled in the registry, see below.

The configuration of WineASIO is done with Windows registry (HKEY_CURRENT_USER\Software\Wine\WineASIO).
All these options can be overridden by environment variables.
There is also a GUI for changing these settings, which WineASIO will try to launch when the ASIO "panel" is clicked.

The registry keys are automatically created with default values if they doesn't exist when the driver initializes. The available options are:

These two settings control the number of jack ports that WineASIO will try to open.
Defaults are 16 in and 16 out. Environment variables are WINEASIO_NUMBER_INPUTS and WINEASIO_NUMBER_OUTPUTS.

Defaults to off (0), setting it to 1 enables WineASIO to launch the jack server.
See the jack documentation for further details.
The environment variable is WINEASIO_AUTOSTART_SERVER, and it can be set to on or off.

Defaults to on (1), makes WineASIO try to connect the ASIO channels to the physical I/O ports on your hardware.
Setting it to 0 disables it.
The environment variable is WINEASIO_CONNECT_TO_HARDWARE, and it can be set to on or off.

Defaults to on (1) which means the buffer size is controlled by jack and WineASIO has no say in the matter.
When set to 0, an ASIO app will be able to change the jack buffer size when calling CreateBuffers().
The environment variable is WINEASIO_FIXED_BUFFERSIZE and it can be set to on or off.

Defaults to 1024, and is one of the sizes returned by GetBufferSize(), see the ASIO documentation for details.
Must be a power of 2.

The other values returned by the driver are hardcoded in the source,
see ASIO_MINIMUM_BUFFERSIZE which is set at 16, and ASIO_MAXIMUM_BUFFERSIZE which is set to 8192.
The environment variable is WINEASIO_PREFERRED_BUFFERSIZE.

Be careful, if you set a size that isn't supported by the backend, the jack server will most likely shut down, might be a good idea to change ASIO_MINIMUM_BUFFERSIZE and ASIO_MAXIMUM_BUFFERSIZE to values you know work on your system before building.

In addition there is a WINEASIO_CLIENT_NAME environment variable, that overrides the JACK client name derived from the program name.
