I just ordered the Presonus 68. I needed the 4 inputs to record my keyboard arranger, vocals and accordion (actually only need three) in my DAW in one take.
Why? Just record the Midi and bounce it through the arranger (or even the accordion if its a Roland) in a second pass. Did sort-of a demo with that in
this video. The basic point is that the Midi allows you to recreate the sound at a later point of time.
My MS40 arranger actually has a song recorder of its own: you can record and replay at arbitrary speed but it would probably not work well for anything but its own sound patches as expander: youd likely use a more generic sequencer for other Midi-to-audio devices. Though you can fiddle around with the input/output assignments a lot: it may even be possible to have only the lead on Midi Out for song replay.
But Ill readily admit that using just one take tends to be more convenient. You should just make sure to avoid ground loops when working with multiple unbalanced sources: sometimes having a spare DI can save the day. Also there are crappy Midi-USB interfaces around with an actual ground connection: complete madness since one of the points of Midis slow baudrate (31250 bps) is to be compatible with the speed of optocouplers providing galvanic isolation, a very good feature for audio production.
