Its a diamond Xtreme PCI soundcard with spdif in/out line in/ out etc. If I isten to the playback through speakers and headphones plugged into the soundcard for the guitar being recorded it is not as bad as trying to monitor both through the speakers (which are being fed via the PCI spdif out to an amp) ... How can the latency be adjusted using the screen that has the VST parameters such as 'adjust for latency Y/N' ' Shift ' and 'Synch with recording or playback' ? Many thanks!
