When Native Low Latency Monitoring is used with <3 ms latency insert FX in either input or playback channels, they need to be processed in two separate audio processes to be heard in both the Z-mix output and other (Standard Software Monitoring) outputs. Whenever such track is monitor enabled, these plug-ins show as “Insert” and “Monitor FX” inside the Performance Monitor. When monitoring is disabled, the “Monitor FX” copy disappears. Complicated? Maybe, but the bottom line is: Studio One always makes sure that Insert FX with low latency can be heard in any monitoring or playback situation.
