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:

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

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.
