I've tried everything to get Studio One to import keyswitches from EastWest Opus sample sets by selecting Action/ Re-load Map from Instrument.
I've tried both VST2 and 3 Opus engines.
I must be doing something wrong.
I've tried many different instruments within Opus (Hollywood Strings, brass woodwind) and added multiple sample types using different midi channels.
It must work based on the YouTube video introducing the feature, but I've not been so lucky.
I have the latest versions of everything
