With respect to monitoring while recording, the EZbus will provide virtually instantaneous "monitor through." In other words, you will be able to record new tracks in sync with those already recorded and playing from your sequencer, and you can use the on-board EQ and dynamics processing in realtime while recording (and, of course, during playback). However, latencies in a computer audio system are a function of getting audio off of a hard drive, into and out of the audio application, then back out to the audio device. These computer/software latencies are not controlled by the EZbus. The EZbus will not introduce additional latencies of its own.
