Hi
You can do a lot with a control surface, but I'm afraid you cannot go completely without a mouse, especially when it comes to editing ...
yet, with the VS-700 (which must be the best integrated available surface) i think you could do without the mouse for long periods ...
... recording/tracking: with good templates in place, virtually mouse free ... 90-95% of all actions @ vs-700 is the estimate for myself (what remains for mouse are routing issues, direct monitoring headphone mixes, and other minor things) - i could potentially push it a bit higher w/ key bindings and other tricks (depends a bit if you just record your own band where you could optimize to perfection or if you do client work requiring different workflows)
... cleaning/editing tracks: 0% for me as I always forget how to do @vs-700 because mouse is so convenient, i reckon you could do some percentage, but no chance for comping or melodyne work ... so the solution would be to keep recording until you/your client totally nails the take ;-)
... mixing: virtually mouse free, close to 100% for me - if you learn all shortcuts to add/mute/delete plug-ins, have a good custom ACT mapping, select/nudge clips from the v-700 ...
OK, plus a keyboard and knowing keyboard shortcuts to fill in on a few new features that vs-700 never adopted/doesn't have enough buttons for (changing screen sets, ...)
i hope that info helps ...
PS: when trying to optimize your workflow, keep reading this forum and asking the guys ... this is a tremendous resource for ideas and how-to's
