A system has only limited resources. Your sequencer uses a portion of
these resources, and leaves the rest to Csound and to Windows itself. If
your sequencer is a heavy application, Csound cannot run properly
(clicks and pops). 
According to my experience, if you drive Csound with a sequencer like
Cubase or Cakewalk, you will need at least a fast Pentium (say, a 266
MHz Pentium II), and this for a limited polyphony. If you have access to
*two* PCs, the better thing is to connect them via MIDI, run the
sequencer on one PC and Csound on the other.
