What higher maths nodes can be expected in the next Metasounds update?

I’m trying to convert a number of my own procedural Pd patches over to Metasounds and there’s quite a lot of missing functionality that would really help.

I have already created a reciprocal and wrap function for audio but could really use others. For example taking a unipolar saw wave and calculating the Cosine of that input.

Or even the ability to read from a wave table by using an audio signal as the reference for which index point (sample) to play would so helpful.

Cheers
