Thanks Graham
As u say 2 issues The midi is odd because usually I find IZZ retains these settings on reopening. As to the HDMI i am a little stumped Yes MacMini OS 10.11.3 / IZZ 2.1 / Geco 1.3.0 Given all things I suspect I will just leave it alone till the show finishes in a few weeks then try with an earlier version of the OS PS - Skyped with my longstanding pal Mike Hodgson in London at length yesterday. He first encouraged me to IZZ way back when and now I was filling him in on recent developments and telling him he must jump back in with Version 2 - Ah the wheel turns.
