Let us know which VST2.x plug-ins are working in Dorico

Dorico
10
  1. Vienna MIR Pro 5.4.15393 (when used as an insert rather than as part of VE Pro)
  2. macOS 10.12.1

Vienna MIR Pro
5653546D6972707669656E6E61206D69

Note: It is useful to use MIR Pro as an insert when not using VE Pro or when using multiple instances of VE Pro to get around MIDI channel limitations. This will be alleviated if Dorico supports the muti-MIDI port feature in VST3.
