This is an old version of Cubase, hoping the same principles apply to newer versions. I’ve just learned that I can set up multiple instances of my Yamaha S70XS (which is accessed via a VST in Cubase), but I apparently have to freeze one VST instance before instantiating another. The Cubase 5 manual says:
‘When you freeze a VST Instrument, the program renders an audio file of the instrument output […] When you start playback, the rendered audio file is played back from an “invisible” audio track, routed to the VST Instrument’s mixer channel.’
But when I render an instance of my S90XS/S70XS VST with a single MIDI track, all that happens is that the VST’s MIDI channel is disabled (grayed out), the VST’s “Activate” and “Edit” buttons are disabled and its “snowflake” icon turns orange. A “Freeze” folder is created containing a 1K WAV file, which doesn’t seem to contain any audio, and hitting “Play” in Cubase produces only silence.
What’s supposed to happen when a VST is frozen?
