You need the Pro edition to use SynthV Studio as a VST. You can see the full list of differences between Basic and Pro on the store page: Synthesizer V Studio Pro - Dreamtonics Store
If the application you downloaded has this icon then you have installed the discontinued “1st-generation” version of Synthesizer V, which is not compatible with voice databases created for Synthesizer V Studio.
This is the logo for Synthesizer V Studio, the current software product from Dreamtonics.
Thank you. Where can I download the latest Studio Pro version (and the voicebanks) to try/trial the VST version properly? I thought I had it, but I definitely have that old logo.
PS I downloaded Vocaloid 6, a very simply process to install, trial and use but once I heard some of the demo English voice banks (Kevin etc) I needed to try this! So far though, the process has been ‘surprisingly’ difficult.
