Dear Colin, Midi-ox is completely new to me, I just tried flashing with 
onlyone midi lead connected, I was assuming some sort of handshaking was 
required.

I got no bad data at all! the display was flashing between something I 
couldn'tmake out and PGM OK @ nnnn
So it's my own silly mistake and I apologise for any time wasting.

It is a short and i shall remove it, it may account for a few oddities I 
may havebeen experiencing but that is probably down to me being confused.

And what a prize!
Paul blew me away with it when he took me through it all last weekend.

Many thanks for all your help.

cheers

Not at all...
Handshaking is provided for a future firmware programming app that will
maximise the speed.
But I really should have realised that P3 should ignore it's own 'ack'
message, for exactly the situation you encountered.
I'll modify that behaviour in future bootloader versions to make it more
obvious when a midi loop exists.

You should have a fun weekend in store ;-)

I wonder if Paul wants to come to Washington DC and have a free 
place to stay (including meals of course) while he takes me through 
my new P3???? Airline tickets are very cheap these days! LOL!

Hehe, would be nice. Perhaps I'll do a video or a webcamcast or
something.... 8)
