FINALLY got around to trying out S-Gear and is everything it is built up to be. Within minutes of firing it up had some great sounds and so it will very soon be being purchased.
The one niggling thing was done slight weirdness with how it was responding to widgets in GP. Now, I am almost completely certain that this is due to the trial version and the trial screen it pops up when the plugin is closed and re-opened - with the plugin open it works fine, when it is closed it can be unresponsive sometimes.
Just wanted to check with those who have the full version that all is good? I am certain it will be but wanted to check first!
