After a bit of trial and a lot of error I have Sibelius playing Hauptwerk via a VST plugin. I have discovered that clicking the "gear wheel" in the Mixer loads Hauptwerk, but it loads it in trial mode with the bell-ringing. How can I persuade it to load Hauptwerk in free mode?
You can change the starting mode once the VST is loaded by going to General settings | General options. Look at the bottom then change the Default unlicensed edition option.
Thanks for that advice. So far the "free edition" has been a little expensive in money and time. My old sound card had far too much latency - like playing an organ 50 feet away through a poor pneumatic action - so I bought a new one and had to remove the old one. Many of my existing applications then didn't work and had to be altered to suit the new card. Next expense will be an additional keyboard. Eventually the paid-for Hauptwerk, more memory and some better samples. That will use up all of my pocket money for a while, but based on experience so far, it will all be worth it.
The more you get into HW, you will see the worth. Sometimes tho, getting "there" in a piece meal fashion can be more expensive than designing a more adequate setup from the start.
