Actually, now I spotted this part.....
I do have the ability to create a wave (audio) file of the equation first and import the wave file into PureDate, but will I have the same control over the frequency,amplitude,phase and vertical offset that the equation gives me?.
Why not import the wave into a table, scan the oscillator with a phasor and add a frequency, amplitude or phase shift in the signal domain?
If that's what you really want to do it's _much_ easier than you might think.
(frequency) | [phasor~] | [+~]-(phase shift) | [*~]-(size of table) | [tabread~ table] | [+~]-(amplitude offset) | (output)
