[linux-audio-dev] Re: [linux-audio-announce] Announce: Vstserver, vstlib, vstladspa and k_vst~ - Linux-audio-dev

Woah!
Tack Kjetil!
I've been meaning to construct something like this for a veery long
time, I'm sincerely happy that you managed to pull it of!
Sometime in the near/distant/close/far future I'll be able to test this
(I'm not holding my breath), I can't wait!
So...next step would be VST synths, any chance you would pursue that? :)
Thanks again,
Robert

  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).

 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/
