feeding dynamic data into formula is causing slow execution and weird results

Please don't equate the two. You can perform natural log equations on a waveform just as easily with DBLs. Just avoid the Express function.

Oh, cool.

I generally try to avoid the express functions, but I was having trouble finding a natural log anywhere else... does one exist?

Math palette. Same place you found the multiply, etc.

Sure enough: Math > Elementary and Special Functions > Exponential Functions

Thanks!
