is it possible to use Art-Net IN and sACN IN without MA Hardware in grandMA3 onPC?
I tried it here with sACN.
I was able to receive DMX and to move the Faders in onPC (no parameters in the receiving onPC).
But you need to switch on the merge mode for your input universe.
To do so, open the universe pool and edit the input universe.
Thank you, it works
Is there a way to use USB-Midi Devices?
I did not test gma3 yet,
but when Art-Net IN is working you can use at least my Midi to Art-Net converter (bomac).
I gave that a quick test. It took a while for me to find the merge mode. I never used it under gma2.
Everything works as expected.
I documented my test in this video:
