I am trying to figure out midi routing in PD. However (1)in the help the midiin and midiout objects show as 'not documented' and (2) inthe midi setup, it only allows for 4 inputs and 2 outputs. I am trying to setup up routing between input and output ports across 4 MidiSport 8x8 units so I have a total of 32 inputs and 32 outputs in these units alone.

Can someone give me some guidance as to how to connect midi input to midi output and also how to extend the inputs and outputs

Thanks
