daqmx generation

[atk_nut]

I'm trying to generate a sine wave on 6 channels at 60hz. I want to "smoothly" transition to 50Hz.

The update rate is 60,000 points per second (that should give 1000 points per cycle at 60Hz.)

I generate a buffer of 1000 points for 60 Hz, then write the buffer of 1200 points (50 Hz) at the same update rate.

However, the signal stays at 60Hz. until I reset the clock. I'm getting stumped. Any ideas?

I've attached some code.

There's a decent NI example that can be found here.
