I just read the manual for the XD9, and even though it does not come with the stereo AUDIO inputs that the X1 had, there is still a stereo mic input that may allow the user to connect a mic (through the vocalizer) and AT THE SAME TIME, a pc, CD or other audio signal (mono, though). Hmmm? Sensitivity may be an issue because the level would have to be set to "mic" for optimum signal/noise ratio, and a line level signal may not sound it's best. We'll have to see.

After speaking with DanO, this was my largest objection - no audio ins .... maybe we have a workaround that will do in a pinch.

The manual is very well written - I wonder if AJ had a hand in it ?
