I'm on a Mac Pro Early 2008 running Mavericks and Ableton 9. I do have Midi Monitor.
Also, when selecting the midi ports the virus is connected to in the plugin interface, the hardware switches to multi-single mode an defaults to a0 --INIT--
Is that normal behaviour?
Also massive huge CPU spikes (over 200%) in Ableton when tweaking hardware parameters with the plugin connected and the virus in Int+Midi mode.
Also, this makes for a nicer GUI imo:
Finishes it of nicely without the need for those rack ears.
