That's right. Separating the `realtime' from the `audio' seems

The url below point to a hackish patch againt 2.4.23-rc1, and yes, it is
very simple. Works by setting /proc/sys/kernel/setschedandmlock to 1.

Hello LAD,
I'd like to propose an extension of the LADSPA specs, or more correctly, a
particular interpretation of the current specs, in order to support the use of
plugins in a 'polyphonic' context.
The problem to be solved is this:

That sounds like incredibly useful software.

The shared library creates a thread for the X code, connects to the X-server

Hi Paul,
have you considered the possibility that Xlib is not statically

this scheme will fail as soon as the host is using Xlib as well.
Yes, and if X does its bookkeeping in terms of 'processes' and not 'clients'

All this would be a lot simpler if the common GUI toolkits would provide
a call that would allow one to create a raw X window that wil be

to a user specified callback. From there on, the toolkit or library used

i'd be interested to hear from fernando about this kind of thing. many
of us on LAD work on what are to all effects and purposes single user
