Audio Ease VST Wrapper 4 supports multiple outputs for instruments, VST bank and preset saving and loading, Sample Accurate MIDI timing, Beat lock and Parameter Automation.
And OSX VST plug-ins are wrapped to become MAS plug-ins, not Audio Units.
Since v 4.1 VST Wrapper reports any latencies introduced by VST plug-ins to the host, making sure that Digital Performer can compensate for it.
Included in the package is an editor for any user preferences per plus, of if a plug will load at all.
