There is no such thing as "omni mode" for a MIDI output. You will have to send the program change separately on all channels that you need.
Omni mode for a MIDI input simply ignores the MIDI channel of the incoming MIDI information but it is always present as the channel number is part of the status byte.

let me outline that also the synth module could be buggy, hence my question

hi list,
ist pgmout without an argument omni channel?
i try to send program changes, and omitting the channel argument
only the first voice/channel of the synth changes sound.
when i manually create four pgmout's with channel 1-4 it works as
expected and the synth changes all four voices.
