> I made this youtube video and track to demonstrate the A-103 filter emulating a Roland TB303.

Thank you! I for one am always interested to hear demos of various modules. Actually hearing them in action is much more helpful than seeing photos and reading about them, when it comes to working out what to buy next. :)

For my part, here's a demo of the A-106-5 SEM type filter, if it's of any use to anyone: http://www.youtube.com/watch v=jQw5N3jZTTs

Thanks,
