Good evening, I ask everyone for help:
I have 2 keyboards that have only midi USB cable and it was my intention to connect both to a Win10 PC (with touch screen) with a USB Hub and find a software (possibly free) that, through program changes, would simultaneously change the sounds to both of them the keyboards by touching only a "memorized scene".
On Mac I already do this with Mainstage, and I was wondering if there was anything for Win10.
Thank you all.
