Finally I have to ask this question here as I can´t find any way to do this:
I want to separate MIDI Channels of the same number to the different USB ports of the Midihub so that I have at least 4x16 channels
My setup is around a RPI Zero with 4 Port USB Extension Shield running Patchbox with amidiminder utility (maybe this can be configured to ports and channels?)
The Synthstrom Deluge as a device does have 1-16 on one port.
And there are some USB Synth as devices and some DIN Synths.
All in all I can´t sequence more than 16 devices from Deluge although the MIDIHUB would allow me to send CH 6 different ports.
