Analogue-sequencer

Hi Colin & All,

Well, I'm waiting for my Hammond case to be finished by Steve 
Thomas, but I couldn't wait to see if the boards worked.

Well, I've lashed the whole thing up over my workbench and for the 
last couple of nights, I've been playing around to make sure 
everything's working. The good news is that as far as I can tell, most 
of it seems to be OK :->)

Top Tip 1: when first powering up the unit; if the lcd backlight comes 
on but there's nothing on the display, don't worry. Turn up the preset 
for the contrast. There it is!

Top Tip 2: before soldering those leds, only to find you've put 'em in 
the wrong way round, Just wedge them in the boards first. They will 
fit and make good contact with just a push fit. That way you can tell 
that things are working (and see the pretty power on light show!), 
and you've found out which way to fit them. Then when you've got 
the case, you can solder them in place.

Now to the problem. I've got s/w version 3.7 which came shipped 
with the boards. Last night i tried to do a sysex dump to the 
computer via midiOX. No problem, that worked fine. When I tried to 
reload this back to the P3, however, I got the 'Bad Data' message. 
(Yes i did disconnect the Midi out back to the computer to avoid the 
loop through). Same thing when I tried to do a firmware upgrade to V 
3.78. I got the same 'Bad Data' message.

I did fiddle around with buffer delays and such, but to no avail. It got 
late and I gave up. Any advice??

All the best

Andy
