Hi there.

I am trying to make a sequencer that will play a bar in eigth-notes and then play exactly one bar where it a completely linear tempo slide from eigth-notes to sixteen-notes. Then it shall play one bar of sixteen-notes before it will, once again, make a completely linear slide back to eigth-notes.

I've made it some of the way, but some of the slides won't work. An even bigger problem is that the metronome starts late after making a slide, which can be seen clearly because of the two bang objects.

Hey.
I need to add this site to my list of litteratur for a paper I am writing. Who was published it?

Cheers!

Hey Data-lovers!

I am writing a high-school paper on Per Nørgård's Infinity series and want to program it in PD, but it just won't work!

Do any of you know how to do so?

All the literature I've read is in danish, so it's difficult for me to explain the concept to you, but the math is like this:

pn[0] = 0
pn[1] = 1

Where 0 is g and 1 is ab; so 1 = one semitone above g and -1 is one semitone below g.

pn[2] = pn[0] - (pn[1] - pn[0])
pn[3] = pn[0] + (pn[1] - pn[0])

pn[4] = pn[2] - (pn[2] - pn[1])
pn[5] = pn[3] - (pn[2] - pn[1])

I hope you understand and that you are able to help. My attachment discolses how far i could get!

Thanks!

Hey Guys.
Pure Data says: "error: midirealtimein: works under MSW only", when i try to make the midirealtimein-object. What is MSW? Can anybody help me?
I have the 0.41.4 version of PD.

Thanks in advance!

This is iteration on real numbers:

Making a patch with chaos theory seems difficult, because complex numbers are construced of both a real number and an imaginary number: c = a + bi, where c is the complex number, a is the real number and bi is the imaginary number. b is a real number that is multiplied with i and i is the square root of -1. For calculation tjeck wiki: http://en.wikipedia.org/wiki/Complex_number ...

It is also difficult for me to describe a discrete case, since I haven't worked with waveshaping by the use of complex numbers, but I know fourier analysis and transformation (PD has objects for these) is based on complex numbers.

Maybe i can fix a patch that calculates complex number, but I don't know what for. It would be fun to make one so I'll try.

I'm sorry that I can't help more, but complex numbers is a complex matter, but I'll think of what i can do for sure!

To clear it out. Chaos is neither integration nor diffenrential equations. It is based on iteration (tjeck out wiki.pedia). It is based upon complex numbers and is used to compose visual and auditive fractals.

I've written a paper on it a couple of months ago. I am very sorry, but it's difficult for me to explain it profound in english, since I'm a dane

It is indeed a very interesting thread!

Drop some of the music at this thread whenever you're ready!

That's awesome! Per Nørgård has made various compositions by using the infinity series. You should defernitely research on him.

I've used the series to make organic, rythmic, developing variations in midi-parameters i.ex. dry/wet on a distortion effect.

Thanks Nau. It's really cool, but more advanced than I had expected at first. I am looking forward to use this series on various parameters!

Thanks.. Yeah, I forgot. Here you go:

The bug is removed from 0.42.5! Never use 0.41.4!

Thanks for you'r help Bonnier.

I haven't tried a 3rd party app, but I am completely sure that Ableton spits out the clock signal, because PD receives the clock if I just follow the three step procedure that I mentioned earlier (first reply). I have tried rebooting, but nothing happens.. I'll download the newer version of PD and see if it helps...

Thanks again. Also a good way of doing it, but the signal do not reach PD. I'm checking it with [print] and [print] do not spit any numbers out.

Thanks boonier, but it wont do...

Well.. the object wont work for me, unless I follow a specific and quite unusual three step procedure:

1. Press play on Ableton
2. Open PD and set the midi preferences
3. Open the PD patch

But then the Ableton Live set and the PD patch are staggered, as you might guess. I've tried quite a bit and this weird procedure is the only one that works..
BTW, I'm using OSX.
