Not really sure what you mean by this. We have a soundbank A constructed from MIDI file using the default soundbank with software synthesizer. It can be used to play another MIDI source. It can be used to substitute any instrument (or multitude of instruments) multiple times in the said MIDI source. Rendering it takes time. In order to use it we will have to render it. Means multiple parallel renders of the soundbank A to play MIDI source if we delay rendering until it is actually needed - that can cause delays in the place where delays are not anticipated.
