Here you go! I'm looping the update because I don't want a big step change in amplitude (can cause my acoustic drivers to blow a fuse) so I ramp the change over a fixed number of steps. I'm using three PXI-6733 AO boards synchronously to output to 18 audio amplifiers that drive the speakers. By changing the offset location, you can insert the new data anywhere in the FIFO you want. Note that I'm not using the card FIFO for regeneration but rather the PC memory.
