If you want to get into this now it&amp;#x27;s actually a good time, thanks to the resurgence in modular synthesizers, which are just analog computation optimized for audio ranges. You can easily find modules specifically for math operations and so forth.</text><parent_chain><item><author>ced</author><text>Off-topic: if an integral is an approximation of a physical process, then that process is an approximation of the integral.
