Function virtualSourceNamed

virtualSourceNamed(virtualSourceName: string): HSMIDIDevice | null
Creates an hs.midi object for an existing virtual source (receive-only — a "source" endpoint can only be read from). the same ARC-related reason as deviceNamed().
Parameters
- virtualSourceName: string
  The name of the virtual source, as returned by virtualSources()
Returns HSMIDIDevice | null
An HSMIDIDevice object, or nil if no virtual source has that name
