true, but there is also a latency in the MIDI interface, in fact in any MIDI thru port on, for example, a synth, you get latency, so if you daisy chain lots of instruments together the last one in the chain will sound a bit after the first. the longer the chain the bigger the difference. thats why the MPC samplers have multiple MIDI outs on them, so you can connect an out to each instrument to avoid the latency associated with daisy chaining.
if you get a professional MIDI interface, like the Steinberg ones, or the Pro Tools one, you get round this i think. there may be others too that work perfectly, but in most home setups, with just one MIDI instrument (the MPC) connected to your PC, you ain't gonna notice a damn thing!
hope this helps
