No customer support available. Payed good money for an interface now discontinued and no support for the current IOS. It is stated on their website that Quantum is supported but it is not. Presonus has not provided a way to contact customer support or even create a ticket. Since the purchase by FMC it's been all downhill. I will never purchase another Presonus product and inform others not to waste their hard earned money.
