I am new, pre purchase, looking at the rm 16-32 series of mixers. (correction: mr-18) pc based, I downloaded the control software, and have a few questions. are the channel strip vu meters post fader? what choices? when recording, are the usb outputs pre? what is the recording application of choice? is there a simple clean recording software that integrates with the mixer, like presonus capture? how does the mixer flip from record to play? thanks for the help.
