Hi,
I used to do that some 10+ years ago with Akai DPS12 and computer. Computers were not very powerful for audio back then. It worked quite ok. MTC sync is not anywhere near to be sample accurate, so phasing issues may occur in simultaneously recorded tracks. Most of the time that was not a problem though.
Of course the best solution is to get an audio interface with adequate number of inputs, much less hassle.
