I'll try to dig into the issue with Carla, although I don't know how many
people actually use it with Yoshimi.

For the record, I do. In fact, with Yoshimi I use nothing but Carla. 🙂
I didn't quite get it from the context, what is the issue with Carla?
- Will and myself engaged into work towards a better separation of GUI and Core
- as a prototypic solution, I developed a new connection system which allows the
GUI to enrol with the core and receive push updates. The prototype uses this
to send effect parameters and especially the EQ response curve.
As you know, the existing GUI code has the unfortunate habit of grabbing right
into the SynthEngine internals, at any time, and without proper thread
synchronisation. The push updates of larger chunks of data aim at resolving
these long standing problems.
For small updates, like single float variable, there is already the toGUI
ringbuffer, and the "returns-update" in the GUI
- this prototype was landed somewhere this spring. But later it turned out
that this made the feature with multiple Yoshimi instances much more fragile,
and sometimes broke it. Especially the mode where several SyntEngine instances
are automatically re-created on start-up.
- this turned out very dificult to solve. In the end, I decided to more or less
rewrite main.cpp and introduce a dedicated InstanceManager and a well defined
lifecycle for SyntEngine instances
- this necessitated rework of the LV2 plugin. I just finished this some days ago
- after welding out some bugs, Will reported that almost all hosts work now.
Just Clara starts, but does not produce any sound. Clara is difficult to build
and is known to produce lots of headaches on the programming side, since it
tends to push the LV2 standard to its limits, or rather actually do what
the standard permits.
