Hi...

I'm quite sad 'bout my P3...

I've powered up only the mainboard
but
the lcd doesn't write at all

so
I've got to go a step beyond
and try to find out where's the problem
and so

what is the current consumption of the main board?
I've checked million of times the layout and components (I work in an
electronics firm...) and I can't
find out where's the problem.

Thanks in advice,

Can you see attempted writes to the LCD ?
The CPU should be strobing pin 6 of the LCD connector.
In one case I have seen, the transistor used for Q1 had too little gain to
drive the LCD enable line.
You could try a different transistor in there, and/or reduce R20 to 10k.

The bootloader will attempt to write to the LCD display, and if it doesn't
see a clear 'busy' flag, it wont continue.
You can fool the CPU into thinking the LCD is responding by removing the
display module, then wiring pin 14 to pin 1 of the LCD connector.
That will ensure the CPU thinks 'busy' is always clear.
If doing that makes it continue booting (you see LED activity), then the
problem is with the LCD interface.

About 200mA.

Hi Colin,
I recently program p3 a lot to trigger drums from NI Battery and use  
it along my machinedrum.
In machinedrum I realy like the option of having a A/B pattern mode   
in pattern edit mode so you have a A pattern and a B pattern chained  
toggling in playback and the displayed edit focus is jumping between  
A and B as well. In P3 we have to choose the pattern edit manually -  
is there a possibility  to implement a A/B mode (maybe ../C/D...) in  
sense for editing (I know you can chain several patterns in playlist  
mode)?

or is it already possible more easy and I've overseen this (user  
config related) ?

cheers,
henry

I've thought about adding a shortcut way of switching to the next pattern in
edit mode, but there's no quick way yet.
Doing it automatically would mean you didn't get the option to 'lose'
changes in pattern edit.

Colin,
if a shortcut would be introduced a back/forth one would be very cool  
to have.

cheers,
henry

I second that!
This is the only thing I've been left wanting since first playing with
the P3!

Hi

returning to the P3 after I while I forgot how something works... or maybe it just doesn't do what I want very easily

I have tracks 1-6 loaded with patterns. I want to copy these patterns to different parts for further editing. This is no problem for changing transposition settings because these leave the original pattern intact but if I want to change the rotation or timebase settings on these copies the editing is "destructive" to the original pattern, so my question is how can I do it without changing all parts that use the same patterns? I guess i need to copy the patterns, rather than the tracks? What is the easiest way to do this?

Presuming you have a pattern with only alternate notes switched on, you can
"sorta" simulate a morph into a 2 pattern mode by halving the timebase and
turning on all the gates.

 

As long as you've pre-prepared all the notes you're switching on it can
produce some quite interesting variations in a relatively smooth way.

 

Not sure if that makes sense, but most of the stuff on here goes over my
head so I'm just getting my own back.

 

:-)
