While the program started mainly as an aid in understanding and debugging VST
plugins, it has evolved into a quite capable program by now which can be really
helpful in a keyboard artist's Live setup.
Since questions do occur from time to time, I've created a
discussion forum for
them.
You can download the current version
here (.zip file, 673K).
Current version: 1.45 - the usual tons of enhancements, bug fixes and internal changes
Attention: if you're upgrading
from an earlier version, by all means read the documentation!
You can download the current double-precision version
here (.zip file, 673K). This is
the same program as above, just with the difference that all internal audio
processing is realized with 64-bit double precision instead of 32-bit floating
point variables; in my opinion this doesn't make much of a difference in quality
(but hey, I'm no sales guy) and just reduces the throughput a bit, but if you
use many 64-bit capable PlugIns, it may be useful.

current
documentation for VSTHost
here (.pdf file, 1.7MB).
Here you can find some VSTHost add-ons that
have been created by ToyleY.
VSTHost Slavery Suite
It was just a little
question in a
forum... "Is there a way to route the output of vsthost to Kristal Audio
engine? And without latency?" that triggered the addition of a slave mode to
VSTHost. And since I got a rather bad taste of humor, it got the above title.
When started with the parameter /slave, VSTHost goes into Slave
Mode and waits for a Master to control it. The first (and currently only)
master is a VST(i) plugin that can be embedded into any VST Host program (even
another instance of VSTHost), called
Legree. It comes as an effect
and as a VSTi, since there are hosts that accept only effects, hosts that only
accept VSTis, and of course hosts that accept both.
You can download Legree
here (.zip file, 85K).
Current version: 1.02

Open Source Variant
Originally, I made VSTHost available including the complete source code.
Since I had to find out that (parts of) it made their way into other people's
programs, and that without even mentioning my contribution, the open source
variant has been frozen. I continue to add bug fixes to the existing code base,
but new features won't make their way into it any more. Starting with V1.16k,
this program is released under the terms of the
GNU Lesser GPL.
Anyway - the important part of the program is an implementation of a VST host in form
of 2 classes:
CVSTHost
This implements the audio callback needed by an effect plugin as a neatly
encapsulated VST host class. This is practically platform-independent code. The
few platform-specific things are encapsulated in...
CEffect
This encapsulates a VST effect, as loaded by the VST host. This class isn't
fully complete - since I don't have a Mac, I've only included the Windows code.
If a kind MacIntosh programmer could fill out the few Mac-specific sections and
send it to me it would be great and, of course, publicized here!

Current version: VST 2.4 rev2 + ASIO 2.0 support, ASIO Channel
selection, bug fix from V1.19-1.43
