Analogue-sequencer

Hi All,

Recently built my P3 and it worked perfectly on power up :-)
Great job Colin!, I find the user interface very intuative too, much 
easier than Doepfer Schaltwerk (anyone want to buy one?) hehe.

I haven't built a front panel for it yet, however one feature I 
would like to add are some extra midi outs, so that I have four 
rather than one, to save having to use a separate midi thru unit or 
keep swapping midi leads.

I know it isn't as simple as just hooking four sockets to one 
output, I'd guess I'd need to split the signal and use non inverting 
buffers before each output - a 4050B looks like it would do the job 
nicely. Can anyone out there help?

If anyone else is interested in this mod I'd be quite happy to 
design up a small pcb, and either post up the gerber files or even 
get a few made and sell at cost if there's a demand

Cheers,
Allan

I've already done this, and laid out a PCB for it for a customised
ready-built unit.
I've uploaded the overlay and foil as PDFs to the files section at
Yahoo.
You need to replace the resistors R4 and R5 with wire links.
The output board then has a BC547 and BC557 configured as a
non-inverting buffer able to drive the 5 MIDI outs.
I dropped the DIN sync output on this board, so if you want multiple
outputs and DIN sync, I'll need to tweak it a bit.

Cheers,

Heyup guys,

been a while since I bored you with a new P3 sequence but today is the
day. 

http://deepbass.demon.co.uk:81/Paul/mp3/

This one is called P3_Stoned37.mp3 and is made using the following
cool trick:

First make a groovy sequence in a muted track.  
Then get the other tracks set up with Aux C to getting ALL from that
track. 
Aux A for each track should be setup to increment Aux D rel 
Aux B should be set to mute Aux C>Aux D accumulator.
Then make each sequence in each track different. But as the P3 plays
and Aux D increases, the sequences get more and more like the groovy
muted sequence. If you set the Aux D behaviour to reverse, they go
back again eventually. Sounds ace - this is just a recording of part
of it because I set the D accumulator to only increase gradually.

You can do cool things muting and unmuting tracks, vary the Aux D
limits for each pattern and also the amount that Aux D is
incrememented in each pattern. Then mess with the limits for masking -
so the morph doesn't occur evenly or even the same on all tracks. 

All these things just kick ass especially as all tracks have their own
basic sequence going that, over time, tend to graduate towards the
common, unheard sequence.

Not sure the example truly demos this as I was fiddling about as ever.
But try out the same thing and see how much fun it is...

Or not. It's sunny, after all.

What's the instrumentation? Was this all played by the P3?

With some drums by the Korg ESX1. But the P3 was playing a Supernova 2
and a Vermona Perfourmer. Did something even cooler later....

Damn - and here I thought you were so expert on the P3 that you didn't need
any synths...

Fascinating stuff! Incidentally what happened to P3_Stoned33 -
P3_Stoned36? So stoned you forgot to upload them? ;) Great demos
though, nice to hear what's possible with the P3 - anybody else got
any they feel like sharing?

Well, I didn't think they really added much or demonstrated anything
cool. And the really, really good ones get turned into tracks.... 8-)

Ditto - let's have more! Come on gang, someone must be spewing forth
some stuff?

I certainly did - this is brilliant!!!

Nice. Is that all run from p3, or are you arranging stuff elsewhere ?
I guess there could be a synced up drum machine at least...

Is that the stuf with the holes in the leaves ? ;-)
One of these days, I'll need to stop programming and start making music
myself...

i nominate gene... he's been silent lately, which i attribute to cranking
out the banging tunes on his P3, heh...

you will hear from me soon... as my final parts are on their way.

and i'm taking most of september off for P3 fun!!!

bleep.
out.

thanx guys
 
the melodys, the basslines and the deep hats are played by the p3 (80% of the song), 
recorded to several audio files which are (i'm sorry:-) arranged... the other drums are synced by the korg, played live during whole track record.
the instruments incl. cutoff, reso, lfo etc. stuff is made with the MagD.logic controller prototype (yea yea ;-)and plugis. i used the p3 for getting the ideas and the concept. oooohhh thanks colin!
 
blablablabla..bumbumbum...nznznznznznz
 
its not the stuff with the with the holes in the leaves, its the stuff which makes 
holes in your brain, so you forget everything you want to do.....what?????... ;-)
colin keep programming, otherwise the p3 would forget to sync....
 
never ever start a song without a P3! 'coz i realy makes u rockin'
 
off

the last parts arrived today...

if all goes well, P3 #41 should be operational this evening...

colin... could you develop a wireless neural interface for the P3 so that
i never have to stop using it? that'd just be an OS update, yes? :)

bleep.

Well I don't know about anybody else but my imagination frequently
needs a good hard kick and there's nothing like aimlessly poking about
with few knobs, buttons and switches to do it. Well that and, ahem,
more 'traditional' stimulants of course.

If we could tap directly into our aural cortex, we wouldn't need
sequencers.
Just imagine the music, and it would be captured onto hard disk...

*sigh*

still, i'm having the same problem as long ago...

i get voltage into D6, and then it stops... only a trickle comes out the
other end.

i have two theories as to waht is going on... either i have the wrong part
in there (50V 1A rectifier), or my powersupply is not actually tip
positive like it's supposed to be, or i've wired the powerjack
incorrectly... i'm suggesting this because i get -9.1V at the input of D6,
and i know from being a nord modular geek that rectifiers cut out the
negative portion of a signal. so i'm guessing that the diode is doing its
job, but it's not getting what it needs to spit voltage out to the rest of
the P3.

if i'm right, is there a way to rewire the power jack instead of getting a
new supply? i'd really rather not buy more parts at this point...

thanks,
f.

bleep.
out.

Sounds like you just have the polarity wrong.
Did you use a 3 pin header for the power input, or wire it directly to
the board ?
If it's on a header, just try swapping the pins round.

BTW normal wiring is centre negative...

yup, it's on a header and the PSU *is* center positive... is it really
that simple? just flip the header around? geez...

i should take a frikkin' electronics class if i'm going to persist in this
DIY craziness. :)

Just a thought, is the power supply outputting DC or AC?
Not all 'Wall warts' output DC. I can't see how you're getting -9v on the
diode.

hi freaks
 
i finally got all the parts for my stainless p3 case. 
you can find some fotos in the yahoo groups.
colin, i realy love this machine.......
 
how many p3's have been made?
