I'm the lead author of Ardour [0], and I'd very much like to hear more about your frustrations, since over the next 1-2 years, paying attention to non-European musical culture is one of the things I hope to focus on during development. You can reach me via the email address in my profile, or maybe use our forums at discourse.ardour.org. Thanks.
