Cannot run demo, getting float>integer issue

[mbrown0294]

I'm having an issue running the demos. I'm running the demo in a Jupyter Notebook, but when I get to generating a tone, I get this error, which seems to be coming from numpy's ramped_tone() function. Any chance you know how to get around this?
