Here’s a little demonstrational Windows program I started in 2002 in order to understand the inner workings of VST plugins – VSTHost. 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.

It’s a VST-compatible host that’s capable of:

• loading VST effects (aka “plugins”)
• parameterizing / editing them
• sound output for VSTis
• MIDI-input and -output
• loading / saving .fxb / .fxp files
• I/O through either Windows MME or ASIO drivers
• Wave Player / Recorder
• MIDI Player

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.

You can download the current documentation for VSTHost here (.pdf file, 1.7MB).

Here you can find some VSTHost add-ons that have been created by ToyleYhttp://www.hermannseib.com
