We haven't mentioned VSTHost before, a little demonstrational Windows program the author wrote in order to comprehend the inner workings of VST plugins. Now at v1.05 it's a VST-compatible host that doesn't really do anything except:
- Loading VST effects & VSTi.
- Parameterizing / editing them.
- Sound output for VSTis.
- MIDI Input and Output.
- Loading / saving .fxb files.
- Full source code included.
