When you say unlock, do you mean they will enable the silent notes of the trial, if Modartt goes out of business? Basically having no trial period anymore, Pianoteq would work for everyone, as if they had paid for it? If so, will it be Stage or Standard? Pro is not available for trial, so at least we can rule that version out.
Sorry for all the questions, just wondering how Modartt would be able to keep this promise. If they go bankrupt, or out of business for any reason, will they have any servers from where new users could download Pianoteq?
Would current users get an unlocking key sent to their email addresses (if they revealed them, you don't have to enter an email address to download the trial)?
Or rather unlocking keys, since there are many pianos available, each one needing a key. With Modartt still in business, each one costing around $49 or somewhat less if there is a sale.
Just thinking out loud here, Pianoteq is a small download as we know, so they could put it on DropBox! Or get somebody, some group or an organisation, interested in guaranteeing access to the product, to host it for free.
