hi,it would be awesome if you could route the analog inputs to a usb output of your choice and not just the (physical) output jacks 
Yes, there is a way to get analog input from a standard USB output. One method is to use an analog-to-digital converter (ADC) that can be connected to a USB port. The ADC converts the analog signal into a digital signal that can be read by a computer or other device. Another option is to use a USB-enabled device that has built-in analog input capabilities, such as a data acquisition system or a sensor interface.
I think you can already route the monitor signal to USB, but it’s been a long time since I read the manual…
