When I last checked the Presonus website, It quoted that the FP10's are compatible with Win10,
other than that I can't help. My Pooters are Antiques, but they are still working !
My HW / Paramount organ is still playing on one of my FP10's utilizing all 10 audio outputs !
I am truly concerned that if at my old Pooter goes "Poof",
will my FP10's still work ?
Please let me know when you have the FP10's playing !
I know that there was a minor fix required in order to use 2 or 3 FP10's stacked.
Are you Using an external Firewire adapter ?
