Defective Records have released v3.1 of the OS 9 version of VSTi Host!
The functionality is identical to the 3.0 OS 9 version, with the major addition of ReWire and DirectConnect functionality. There are also some bug fixes, including fix of a problem recognizing some OMS input devices, and better handling of some problematic VST plugs.
For current paid users of the OS 9 version of the application, this is a *free* upgrade. A demo version of this new update is also available on the web site.
