Render-In-Place Bug: More tracks than the single selected MIDI track are rendered if they share the same VSTi

Render-In-Place (RIP)

Repro

  1. Have a project with multiple MIDI tracks routed to the same instance of a VSTi
  2. Have the red “S” solo button activated on all the MIDI tracks.
  3. Select one MIDI track, choose RIP from the menu at the top, choose the first option (“Dry - Transfer Channel Settings”)
  4. RIP
  5. Listen to the rendered audio track: It includes audio from all the multiple MIDI tracks routed to the VSTi, not just the single selected MIDI track.

Workaround
Mute all the MIDI tracks routed to that VSTi except the one that you want to render. After RIP - unmute those other MIDI tracks.
