Can I record 4 tracks in parallel, or two stereo tracks with an 'icon cube pro' USB interface with 4 inputs. The Samplitude help index: tutorial refers to an MR64 control panel under recording but the MR64 icon that should be there, looking like a tiny tape cassette, seems to be absent from my panel and not in any of the pull-down menus.
