It would be really helpful if one could attach a particular TTL value to a particular stimulus so that the TTL value was automatically sent to the designated port in sync with the presentation of that stimulus. Perhaps this could be implemented as a series of meta-commands at the top of a script file, or the TTL value could be listed with the stimulus name in a stimulus list. This would ensure that a stimulus pulled randomly from a list would automatically announce itself via TTL to associated equipment (e.g., computers controlling physiological amplifiers).

If there is a way to do this in v2008 DirectRT that I am overlooking, I'd appreciate a heads-up.
