Hi, I'm working with Pd-extended 0.42.5 on linux ubuntu 12.04 and I can not send custom sysex messages (just start and stop are recognised) if there's more than one midiout on the system.
I use a Roland Mc-505 on Midiout 1, a Korg Tr-61 on Midiout 2, a Boss Sp-505 on Midiout 3 and a M-audio Venom on Midiout 4
I tried just with one midiout and it works fine sending any kind of sysex message..
Anyone trying the same??
PS, I tried using another instance of pd but I need five (one for each out + main patch) at the same time and it seems a little impractical...
