Hi and massive thanks for the answers to my two previous questions. I will calm down from posting very soon. I have one final question if people could point me in the right direction. I now can read my data and print it out using get text. I want now to map this data to a range of frequencies so that my lowest value triggers 50hz sine tone, and my highest 13k hz. I need to know how to tell pure data to do the mapping, and how to send the values to the oscillators. Quite complex perhaps, but I plan to spend the next few weeks tinkering with this. Many thanks again for the help so far.

There is a mapping equation:

And with [mtof] (midi to frequency) you can get that exponential/logarithmic pitch to frequency curve.
