Thanks for your help but I don't believe VSTHOST is the problem at this stage.

Whatever is responsible for routing midi and audio is the cause of the problem. It does not function correctly all the time. Works most of the time, but not all of the time.

Simply starting and stopping the HOST engine is enough to kill whatever is routing the audio on the Meidastation.

Yet I can do whatever I like on my Laptop here with VSTHOST and can't find any problems at all.

James
