I just tried to play this from SoundCloud but was met with a non-existing track message. :-(
I did a poor job on that demo track and took it offline. I think the DervishD multi itself is good but the audio demo didn't meet my quality standards. I am definitely going to record a demo that is worthy of the original track. If you have an Origin you can download the multi for this and play around with it yourself! One thing I would like to improve on is the Vangelis "harmonica"-type solo instrument.
If you really want to listen to the substandard demo I can send you a private link...
