Don they all flash 8 at turn on. It is onyl when you hold the buttons at startup that you get the OS number.

In answer to Diki, yes. It seems the speed of modern interfaces in transmitting Sysex is so fast, that the H-m's sysex buffers cannot keep up. It gets overloaded and the upgrade fails.

I agree 100% with Don that TC Helicon should have taken newer, faster interfaces into account when preparing the upgrade.

My interface was the very simple Edirol UM1-SX, and even it had issues with the release 1.7.

However the guys at helicon did "something with it, and gave setting suggestions for Midi-Ox and it worked.

To re-iterate my coment on another thread, the tech support service is not exactly stellar either, so I also agree with Don there...the average time between replies to my emails to tech support was 4 days, and it took around 2 and a bit weeks to get it accomplished!!!
