Analogue-sequencer

Hi guys,

Finished my P3 yesterday.
I was lucky, it booted immediately.
I saw the clock signal on the midi out too.
It was kind of late already so I didn't really tested it but I wasn't able to trigger any synths though. Need to read the manual.

One thing I've noticed is that the display keeps jumping to step 8 and velo goes up and down all the time.
(If I remember this correctly, it was kind of late) Is this normal behavior?
When looking closer I noticed I swapped the upper and lower pot board, but since they look the same I don't think this is the issue?
Any ideas appreciated.

I'll try some more tonight...

Cheers,
Tom

Could be a dodgy pot. I had a similar problem with the note pot on 
step 11. After swapping out the errant alpha pot, all came good 
again.

Good luck

it could be that, or if you have an older OS (like the one that comes
burned on the CPU) that might be the problem too... sometime recently,
colin changed how sensitive the knobs are (*snicker* must be all those
knob grab events!). several people were having issues like those you
describe... whatever system read the pot positions was too sensitive, so
subtle variations in the environment could cause the P3 to think you
twiddled something and jump to that step...

upgrade to the most recent OS and see if that solves your problem. if not,
definitely replace the pot.

bleep.
out.

I would guess at a combination of the older OS and too long a ribbon cable
as the probable cause if the pot changes happened across a number of
different pots.
If it's just the one step that's doing it, it's more likely to be the one
bad pot.

One unforseen problem with the newer OS is that it can hide a bad pot...
I'll maybe add a diagnostic mode so you can check for a bad pot.

When sending the sysex file  I get a "Bad block!X" message on my display...

Any chance you have a midi loop ?
P3 sends a sysex 'acknowledge' for each code block it receives - if this
loops back through and P3 sees it, it will display bad block.

If that isn't the problem, it could be the opto-isolator. Some 6N139s work
OK for short midi messages (notes etc.) but during a longer sysex block,
their output seems to latch up somehow. I'm going to switch to 6N137s for
the next run.
You can usually get a dodgy 6N139 working by removing R3.

Cheers,
Colin f

I solved the knob problem swapped out the bad knob.
I'll try the sysex thing later. (yes I had a midi loop)

Thanks to Paul Nagle I even got to play a little tune!! Make me a whole 
mp3 based tutorial please.....;-)
Thanks, you made my day!

Cheers,
Tom

Glad to be of service. Yesterday I had planned to make a short avi
explaining tap/sculpt. Instead I turned on the P3, fired up the bong,
next thing I knew the afternoon had slipped away from me. Maybe
today...

If there's no loop, and you get a bad block message, remove R3.
If that doesn't work, the best bet is to swap the 6N139 for a 6N137.

okay, 
thanx!
