pc is an i3 with windows 8.1, connected with cat5, macbook w/ yosemite connected with firewire, and iPad v9.1, connect on wifi. Just updated all apps and firmware to newest that are available. I use the PC with 23 inch touch screen as FOH, the macbook at stage for playback/recording/smaartlive, and the iPad as remote monitor mixing on stage. The input metering just disappeared after updates. Is this a firmware problem or a PC application problem?
