RicRob,
I didn't run all the tests myself since I don't have the need to, everything seems to be doing ok (knock on wood) except for one instrument sound and I don't care much for that one anyway.
I tried 2, 3, 4, 5, 6, 7, 14 and 67 to 71. Number 7 gives a tone going up and eventually says TG1 check. Number 14 gives a steady tone and I ended it myself and it says Check. Number 69 takes awhile but comes up with OK. I tried 28, but only on the left side all led's came on, nothing right of the display, don't know if that's normal, but they do work in normal mode. Other numbers, I haven't tested.
But I can see that a pedal test would "hang" if there is no pedal connected, same goes for USB or card check if nothing is connected to it.
As far as the OS goes, mine's 1.01, but like Gary says, I don't see the need for an upgrade, I'm not about to download their high priced songs anyway, and I don't find any info that anything else major would be changed.
I don't know nothing about the vocalizer since my PSR1500 doesn't have that.
