New subject: [PD-announce] Announce: Vstserver, vstlib, vstladspa and k_vst~

      VSTServer V0.0.1.
-----------------
	First release. Beta, but usable.

ABOUT

	Vstserver is a wine program that must be running when using programs
	using vstlib.

	Vstlib is a library that can be used by programs to run windows
	vst audio plugins under linux/freebsd/i386solaris/etc.

RUNNING
	Vstserver is started like this: "wine vstserver.so".
	You probably want to set the "VST_PATH" environment variable pointing
	to your plugins first.

DEVELOPMENT
	Vstserver is released under the GPL, and vstlib under LGPL.
	If there comes many source-contributions, I will probably make it
	a sourceforge project. To use vstlib in a program, look at
	the tests/exampleclient program, and various vst plug-in documentation.
	The interface to the vstlib consists only of two functions (new/delete),
	the rest is like you would do when programming for windows, macos(X),
	beos, irix, etc.

CURRENT STATUS
	Vstserver seems to be very stable. I have not found any plug-ins
	that wont run, and I am not able to hear any latency. And plug-ins does not
	seem to cause more cpu-power than under windows.
	No GUI or graphics-support yet.

BUGS
	1. When running the ladspa "listplugins" program many times in a row,
	I get the following errors before the server freeze:

	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:region:CombineRgn Invalid rgn=0000
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:region:CombineRgn Invalid rgn=0000
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:region:CombineRgn Invalid rgn=0000
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:local:LOCAL_GetBlock not enough space in GDI heap 01f7 for 24 bytes
	err:clipping:CLIPPING_UpdateGCRegion hVisRgn is zero. Please report this.

	I dont know what this is. Its not errors coming from the vstserver program.
	It seems to be related to X, allthough no graphics is used in the vstserver.
	I hope its just the buggy libXrender.so library that wine shouts about each
	time it starts.

	2. Shared memory handlig might be faulty. I suspect that it doesnt free
	resources. (see server/shmhandler.c)

	3. I havent read the vst plug-in documentation yet, and dont know everything
	about it. This especially goes for the "AudioMasterCallback" function, which
	for now just returns 1. I guess some more work needs to be done in this area,
	and for the various dispatch opcodes too.

	4. The processReplacing function in vstlib should perhaps be made just by calling the
	process fuction. But I dont understand the difference between processReplacing
	and processing.

FUTURE
	Add GUI and graphics support to the server (help wanted). And maybe make a
	DX-plugin server. (would be fun running pi-warp under linux).

CREDITS
	vstserver and vstlib are made by Kjetil S. Matheussen / Notam.
	k.s.matheussen(a)notam02.no

	Some programming hints is gathered by looking at the pd vst-object plugin~ source
	and the jack soundserver source.

vst ladspa plugin v0.0.1 - alpha
---------------------------------

Makes vst plugins located in $VST_PATH
appear as ladspa plugins.

I'm not sure how well this one actually works.
The northpole plugin seems to work, but others
don't. Oh well, its alpha for now.

k_vst~, a Pd tilde object for hosting VST plug-ins.
---------------------------------------------------

   This is really just the plugin~ source made by Jarno Seppänen,
   but with a few lines changed (very few that is) to make it
   work with vst-plugins using the vstlib.

   The name was changed from plugin~ to k_vst~ to avoid nameclash
   with the plugin~ object running ladspa plugins.

   This object is for i386 non-windows (ie. linux/freebsd) only.

   This one works very well!

-------------------------

vstserver, ladspavst and k_vst~ are open-source programs made at Notam /
Oslo, and can be downloaded from from http://www.notam02.no/arkiv/src/
