Req: INTERNAL BUSES

sorry, let me be more specific.

What i did-
To record the output of a VSTi (or for any internal mixdowns) onto an audio track, point/send/assign it to a dummy out (F10-Audio Connections-Outputs) and assign the input of the audio track to that path.

What i got-
Trying to use these buses hangs Cubase, repeatedly. However I haven’t tried it since upgrade to v10…
