[linux-audio-dev] Re: [linux-audio-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

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

I dont know what this is. Its not errors coming from the vstserver

It seems to be related to X, allthough no graphics is used in the

I hope its just the buggy libXrender.so library that wine shouts

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

about it. This especially goes for the "AudioMasterCallback"

for now just returns 1. I guess some more work needs to be done in

and for the various dispatch opcodes too. 4. The processReplacing function in vstlib should perhaps be made

process fuction. But I dont understand the difference between

and processing. FUTURE Add GUI and graphics support to the server (help wanted). And maybe

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

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/
