Can I affect virtual instrument settings on existing VST host?

Can I manage them without writing my own vst host?

For example, I don't need to write a vst host to send note to it, if existing one can accept external sequencer. - I can send MIDI messages to it using NAudio, C# and virtual MIDI cable.

    Note that not all VST plugins respect the MIDI GM correctly (ie, the "MIDI CC purpose" column in that document).
