I think GPO is a great library and I want to thank Gary for making it available for such an affordable price. I also own Sonar which is a great tool and provide a nice plugin interface.
Being first of all a programmer I would like to write a MFX plugin to improve GPO usability in Sonar. First thing which comes to my mind is a real time input filter to transform velocity or breath control #CC2 (thanks to ghostwriter for this) into mod wheel control events #CC1. That will help other people like myself having a MIDI controller without a mod wheel.
So here is my request: I would like to ask this forum for more input and ideas to include in the development of this plugin.
Being a strong supporter of open source this will be available to anyone for free.
