I have some sensors I would like to continuously monitor, as well as some projectors I would like to send a signal to at undetermined times (i.e. everytime I press "Play Signal"). Is it possible to independently trigger Analog Output data while continously recording Analog Input data? I am using an NI 6366 USB DAQ.

It should be fine. Just set up your AO tasks *without* calling DAQmx Timing. This will leave them in a software-timed on-demand mode. In this mode, each AO channel could have its own task. (When hardware timing is configured, most boards would only allow one AO task to be active at a time.)

Wow, that's some gadget! [I'm used to its tinier cousins, the USB-6009 and USB-6002). You use the phrase "independently trigger Analog Output data" -- do you want to output a waveform (an Analog signal) or generate a "trigger", a basically digital output? The Good News is the device has both AO and DO capability, and it is definitely possible to have multiple DAQmx tasks running simultaneously.
