Beginner question DIN USB more than 2 devices

i just received elecra one mk2

i connect a mix console to usb host, it is recognized and i can control it.
i can also send midi control messages to a synth at midi Din Out2, it works
when i send command for example to usb device i see the usb flashing at top of sreen and also the midi1 out

the manual say;
One preset may have up to 32 devices configured. All of them can be used at the same time.

i don’t understand how connect ands control more than two devices.

Hi, you use separate midi channels, and chain your external midi devices together if necessary.

ah yes of course, so it is not real multi midi device. I will go with my mio XL.
for just control devices it would be nice for some users to use usb device out and also use midi din out 1 and 2 without routing/merging usb/din

You can use the 2 midi din ports as well as the USB port (even with a hub, iirc there was recently a question about that) simultaneously, but I use my Mio as well :blush:
