I think it's a technical limit of Pd... I've Pd vanilla 0.41.4 compiled by me on GNU/Linux, If i tried to set 48 chan. I gotmb...@mbutuarch ~]$ /usr/bin/pd 48 output ports not supported, setting to 32 pd_gui: pd process exited Segmentation fault So i think you need more instances of Pd.
we are using Pd successfully with 64 channels. usually with alsa as backend.the jack-backend of Pd is buggy and only supports 32 channels. it will also crash if you are setting higher numbers of channels.
i have once posted a bugfix for this to the patch-tracker that raises the maximum number of channels to 1024, but people reported problems with that.
just yesterday i have done tests with jack and 64 channels (with a modified patch applied, the modification was to reduce the number of channels to 256, iirc), and had no problems at all. according to jack, i was down to 2.5ms, and i _measured_ a latency of 10-11ms.
there might as well be problems with OSS and higher number of channels (hidden within the depths of OSS)
