Eric (Bjorklund), if you see this please comment!
I could use the waveform record (or genSub record) to achieve what
I need (sending a waveform to an arbitrary waveform generator), but
I took a look at the aao record because a) waveform record is obviously
intended mainly for input and b) the aao record was there.
However, I am willing to implement the changes and test them. It is
not so nice to have things in the distribution which are obviously broken.

For me it is easy to modify what I have now, because it is in the
beginnings. Could people who are using aai/aao comment on the implications
of changing the record support code?
