Yeah, Jon, got it and installed it (and IIRC I think I posted to the group) and found absolutely nothing I could document as different.
I will investigate the transmission question you have this weekend (still packed up from a gig) and give you a report.
Ed, Did you ever get the v1.04 EPROM Yamaha sent you installed? How did it work out? If so, can you check whether the Arp/Seq will now transmit when LOCAL = Off?
