STAM: Thanks for performing the test on the Korg PA80. I'm happy to hear that your PA80 came up with 'correct' chord recognitions for almost every one of the melody notes played (except for perhaps Bdim ?!). This points out (to me) that the slash chord 'on bass' type chord recognition Yamaha chose, may possibly have been an oversight problem that Yamaha never really looked into. As I reinterated before, I only hope Yamaha will take at serious look at this BEFORE releasing the Tyros.

J Larry & Freddynl & Dennis (TwoNuts): Many thanks for your input & support on this issue as well.
