I'm buying VSL SE+ next week, and am thinking of buying Notion. It would be a nice feature (since you are planing on including support for the larger sibelius collections too) if it could automatically read from the syncrosoft key which libaries are installed and let you choose from those in the templates.
A plugin to adapt the shortcut keys to match sibelius would be amazing too! ... :)
also how much RAM is needed to load the entire full orchestra Template.
thanks
