Thanks again Martin! That one bit of knowledge has opened many doorways for me! :)
Btw, I was looking for different ways to define a ramp input, or to send a pulse at different times.. and was looking at how I could possibly just record a pulse into a file then send it at certain repeat times.. As opposed to chopping a cosine with a vector of 1s and 0s or something...
