I do this using throw~ and catch~ where the mapping happens in an abstraction within a clone object. I've used this heavily for spatialized projects at work up for up to 64 channels.
Here is a simple solution using Han's c_urn suggestion to do the random number generation: https://github.com/danomatika/BangYourHead/tree/master/3.Audio/rand8player <https://github.com/danomatika/BangYourHead/tree/master/3.Audio/rand8player> This could be further cleaned by using an output abstraction that wraps a [dac~] without creation args so you can set the output channel. You could also integrate the [dac~] into the existing channel map abstraction too, but I figured it was easier to read using a single doc~ object as an example. if you want further heavy usage of this approach with multiple mapping layers, see https://github.com/zkmkarlsruhe/ZirkoniumSpatializationServer <https://github.com/zkmkarlsruhe/ZirkoniumSpatializationServer> > On Oct 5, 2021, at 4:12 AM, [email protected] wrote: > > Message: 1 > Date: Tue, 5 Oct 2021 00:08:22 +0200 > From: Simon Iten <[email protected] <mailto:[email protected]>> > To: Pd-list <[email protected] <mailto:[email protected]>> > Subject: [PD] Fwd: random routing of 8 audio-streams to 8 outputs > Message-ID: > <cap9nqknmyn6ojsfp9ujbcf-znykr5qrp6qnbxa60pocblsu...@mail.gmail.com > <mailto:cap9nqknmyn6ojsfp9ujbcf-znykr5qrp6qnbxa60pocblsu...@mail.gmail.com>> > Content-Type: text/plain; charset="utf-8" > > is there a somewhat elegant way to route 8 audio outputs (from readsf~) to > 8 dac~ outputs randomly (on a bang for example)? > > i.e. out1 to dac4, out2 to dac7 etc. > > each output is allowed to one dac~ channel only. > > mathematically speaking that would be 8! 8x7x6x5x4x3x2x1 (40320) > possibilites, but i don?t see an easy way to program this in puredata. > > some way of dynamic patching maybe? or a throw~ and catch~ approach? i get > stuck on the random logic, since every ?step? that chooses a destinations > changes the subsequent outputs that are still allowed to be chosen. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
