25. monitoring latency is that slight delay you hear when you run an input signal through your host audio software For example you might hear it when you drive a live mic input signal through a reverb plug in running in your audio sequencer This delay is caused by the amount of time it takes for audio to make the entire round trip through your computer from when it first enters an 8pre input passes through the 8pre hardware into the computer through your host audio software and then back out to an 8pre output If you don t need to process a live input with plug ins the easiest way to avoid monitoring latency is to use the 8pre s CueMix DSP feature to patch the input directly to your monitor outs via the 8pre audio hardware This is just like bussing inputs to outputs in a digital mixer For details see CueMix DSP hardware monitoring on page 48 If you do need to process a live input with plug ins or if you are playing virtual instruments live through your 8pre audio hardware you can significantly reduce latency and even make it completely inaudible regardless of what host audio application software you use This chapter explains how Itisimportantto note that monitoring delay has no effect on when audio data is recorded to disk or played back from disk Actual recording and playback is extremely precise Monitoring latency does not occur when operating the 8pre as an optical expander in converter mode Monitori
