Hello Jens,
Thanks for your reply! I know that an exact replication is not possible on different machinery, however, I currently face the issue that my sound onsets jitter a lot (-20ms to +30ms lag, relative to a parallel port eeg marker). Other lab member achieve 19ms lag with basically no jitter in NBS Presentation. I am pretty much stuck, having tried all combinations of settings (similar to Inability to have precise timing for auditory stimuli), even in barebone experiments with only and audio stimulus and the marker. Do you have an idea? Best,
Tim
