I had been beta-testing the IOS version of Camelot Pro for some months. I don't think I am interested in the PC/Mac version yet as it is only a standalone, and not a VST plug-in. I am not ready to replace Gig Performer with anything else. As for the IOS version, even after the public release, the company still updates the beta version and lets me use it. Now, there is a similar app that seems even more powerful; KeyStage; here's a church musician giving a demo on it. https://www.youtube.com/watch?time_continue=15&v=g3ZSiJT3jmc
