Perhaps we should add, that this does not work for virtual synths, or if
the musician is dependent to hear the long-sustain-over-overdrive-delay-
wah-wah-virtual-amp-plug-in during the recording. A hardware monitoring
done by a sound card or by a mixing console allows to hear the already
recorded tracks + the signal of what you want to record directly, so you
can monitor already recorded virtual synth and already recorded guitars
using the long-sustain-over-overdrive-delay-wah-wah-virtual-amp-plug-in, 
but you cannot monitor virtual synth and such guitar plugins without
latency during recording them. You only can monitor the clean guitar
signal and external synths without latency while recording them and
after that, when playing hear the guitar + plug-ins and virtual synth.
