Excellent! 6 ... that'd be pain to tune! The S10 is only 2 and my VStrom is only 2. FWIW, you can always tune one at a time keeping one of the ports as a reference. Not perfect but it will do the job.

@tz89 I have been working on a similar project with a couple of folks over on the Yamaha Super Tenere forum and the ADV forum. There was a guy making one called a "Harmonizer" but he has stopped for the time being so some of us are giving it a go. I stumbled across your work after getting going. I am using off the shelf components from FreeScale to hook up with the Arduino. If it is OK with you I am going to use some of your code - I'll publish what I come up with over on the S10/Adv forums and perhaps on GitHub as opensource. Is v01r06 the latest and greatest? If you want to PM me we can exchange email address' - I am just a short term guest on here since I don't have a related m/c. Thanks Chris
