Reaktor 5 or lower

DESCRIPTION

This instrument uses five instances of Rössler attractor generators with different initial conditions (controlled by fader I )
Fader C is control parameter for Rössler attractor.
RX5 matrix, allows individual switching on/off for different time series (audio signals X, Y, Z generated by attractors) creating some interesting effects: try leaving only switched extreme buttons or any nice looking combination.
Env global is there just as a trick to avoid start and end clicks for midi notes, but is useful for shaping too.
Modulation section uses audio in, or internally generated sine and tri waves for modulating I and C parameters. Try with low ->I and ->C values. Mod pitch is only for internal modulators sin and tri and is an offset in midi note units.
As usual, display is not satisfactory and needs much more work to do.
MIDI monitor can be easily removed from instruments structure.
Tested with an intel mac core duo, running smoothly with 16 voices. For older CPUs please lower voices count or sampling rates.
Enjoy !!

hello mr garriga, thanks a lot for this great object. tried it on a 2.2 ghz intel core i7 on a sample rate of 176400 (cpu load about 75%). when set the clock divider to 1 it sounds unbelievable and shows what it is supposed to. at lower sample rates it's very slow and almost inaudible (half of sample rate sounds 1 octave lower).so we obviously have to wait for more cpu power but it's worth the patience

I have asked about performance in other forums and awaiting for more info on it running on windows. Anyway, you should be able to use lower sample rates, cause I think there is nothing inside "tied" to 44.1 You could also try checking simpler implementations of the same ideas, available for free download at: http://www.nonlinearinstruments.com/images/stories/Sources/Reaktor5Sources/ There are several previous versions folders, may be some of them will run and give us a clue on what is going wrong. Sorry for this, I'm afraid I'm not qualified for Reaktor suport :(

Ignasi, Unfortunately I never was able to get this to function. I'm using a 1.67 PB G4 and it was immediately overloading the processor. So I would keep backing down the sample rate in an effort to run it, but I think that it only wants to perform the necessary calculations at 44.1. I'm not sure if thats correct-just a guess. I can't even get anything to show up on the display. I was really looking forward to this. The rossler is so promising for music. Strange, because I can get a rossler running in Supercollider with very little processor effort. In any case, thanks for this, and all of the other very interesting work that you do. Will be looking forward to future uploads from you.

I am sorry I could only check it with my mac. I am using Reaktor ver 5.12.009. I will try to check it on a friend's PC and see if needs some hacking to make it run in slower machines. Meanwhile, thanks for your interest. Mr. Dean : Should we be so formal in this forum ? I mean, you can call me Ignasi ;) please inform about your experiments !! Had some problems with hacker attacks on my site, but nothing essential has been lost. Will try to find time to reconstruct it. Thanks, too, for your interest.

Cant seem to get it working on a G4. It runs, but doesnt seem to affect incoming audio, or generate tones.

sounds interesting but it immediately overloaded my processor... ;(

Hello Mr. Garriga, Very glad to see you constructing again. I'm excited to experiment with this over the weekend. Thank you for your efforts. Now to see if your site's back up.
