Analogue-sequencer

Folks,

Firmware v3.90 rev 3 fixes a slight bug with the realtime record 
settings that may cause odd behaviour in edit mode. In Yahoo files 
now.

Cheers,
Colin f

Yes.  Or, as was sugggested to me the other day, rest them in place gently, so as at least then you can tell what mode your in.

I think it's been mentioned before, but the easiest thing to do is to 
just wedge the LEDs in the pcb holes without actually soldering 
them. That means that when you switch on, they will still work and 
you can see what's going on. (and see the fancy bootup lightshow :-

Also, if you're using an lcd display, don't panic if you can't see 
anything at first. Adjust the contrast and the display should come 
good. For PLEDs I think this adjusts brightness.

Good luck

Andy

And dont get worried, as i did, when all the text on the screen is scrambled.  The memory needs to be initialised.  Its at the back of the manual.

hi there...

my p3 is nearly complete (though naked). i have held off putting the LEDs
in until i have the case, so will i be able to turn it on and test it out
without them?

thanks,
f.

bleep(good with an iron, bad with a schematic).
out.

man, i must be losing it... now i remember commenting on that thread.
thanks for the reminder... i hope to have a functional P3 tomorrow night!

hi all...

i've got 10 hard-to-find P3 memory ICs for sale, $2.00 each. i found
someone who had 13 and i bought his whole stock. i'm using one and two are
already sold. you could try getting them from digikey but you'd have to
wait until july. bad news.

bleep.
out.

There's just a single pin used on this connection - it was a late
addition to the P3 design.
It's an open-collector output that drives the LEDs on the function
switch board. The original LED matrix was only designed to support 32
LEDs (16 x 2 in tri-colour LEDs). When I decided to add dedicated
function select switches (they used to be soft-keys in pattern edit mode
only) I used one of the four spare TTL outputs on a 574 latch to drive
the extra row of LEDs.
The 4 pin connector is on the mainboard in case I ever think of
something to do with the other 3 outputs.
I might, for example, design a little board with a 7 segment LED on it
that will display P, L or E for the current mode, and lose the inverted
video characters from the PLED (optionally, of course).
There's a 2 pin connector on the function board because 1 pin connectors
don't stay connected very well.

Cheers,
Colin f

interesting... thanks for humoring my curiosity.

it's done.

all the parts fit. i have verified this with my own P3. the only
difficulty is the fuse... it doesn't quite fit but can be made to. also,
the appropriate panel mount pots seem to be backordered at the moment. i'm
just going to use pcb mount pots for data and temp though... soldering
that will suck.

in the .xls version, there is a second spreadsheet. copy and paste this
into Mouser's BOM import tool and you'll be *done.* the pages at the end
of the PDF version should allow you to do this too. these are the pages
with just partnumbers in one column and quantities in the next.

enjoy,
fred.

When leaving the playlist edit (see user manual page 20) and pattern edit (p.30) 
modes, you are prompted to select whether you want to save, go back  to edit some 
more, or lose the edit. Selection is made using one of the softkeys F1 to F3; and it all 
happens transparently when in playback. Chains are automatically saved, although 
this is lost if you switch banks.

i breezed through the manual again and could've missed the answer to my
question, but how does the P3 deal with saving things, patterns,
playlists, chains, etc.? and can you do this while the sequencer is
running? or is saving automatic, like the mobius?

thanks,
f.

All happens during playback without interrupting anything. In, for
example, pattern edit, you get the option to save to another pattern
or to lose changes before exiting edit. Works an absolute treat.. 8)

it gives you the option? wonderful... but can you save to the pattern
you're working on, overwriting it?

'Save part on bank change' is on the TBI list.
I was also thinking of changing the bank select so you have to hold the
bank key (F1) then press the step key.
FUNC+BANK+<Step key> would select a new bank without saving the current
part in the old bank, similar to FUNC+new part.
I find sometimes I hit bank by mistake, then have to hit Cancel before I
can return to muting tracks etc.
Does anyone think that wouldn't be an improvement ?

Maybe on the next run, I'll add pads for a 'proper' fuse, instead of the
electronic one.
Bear in mind you could always use an inline fuse holder in the power
lead, or just live dangerously and put a wire link in (a.k.a. 50 amp
fuse)

I always use PCB mount pots myself, and just solder wires to the pins. A
bit of practice makes it easy.

Very handy. Pity no-one in the UK does that...

You can save to the current pattern (default) but one think I like to
do is save little variations to different patterns that are not
selected in a current playlist. Then, when I select a new part, I
adjust the playlist so that eventually I have a series of parts that
have slightly different patterns. I then string the parts together to
play in series - and all this as easy as pie as you play. Even live.
You can also extend playlists live, adding the variations as you make
them and that's something I've started to do more and more.
