i was about to report an issue on the pd github - but since i really don't know what's going on, i thought i'd share this here first and maybe someone has an explanation for it ....
i've been experimenting with a simple patch for random-walking the surface of a sphere. the current algorithm is not very elegant since it uses random steps that don't have equally distributed distances (but rather form the shape of a cube). i use 1-sample-send~/receive~ to feed back the current position for the calculation of the next position. the weird thing is that it works perfectly well if i output my coordinates with 3 outlet~s ... but the result looks different for the exact same algorithm if i output it via 1 multichannel outlet.
so it seems like the outlets are affecting what's happening inside the subpatch?!?
here are 2 screenshots for these 2 cases - with 3 outlets:
with multichannel outlet (the coordinates are no longer on the surface of the sphere, but start to blur into a cubic shape):
and here's the patch for testing (vanilla besides requiring Gem ... and the relevant part is in the 2 subpatches obviously):
