How to achieve through zero linear frequency modulation?

Alex Muscat's icon

I've implemented frequency modulation before and looked over the fm MSP tutorial, but I'd love to be able to implement through zero linear fm in a patch.

Does anyone know how to accomplish this? I've read through some resources online (although not MaxMSP specific), and it's difficult to understand how to translate these concepts into a patch.

Thank you!

By default FM in Max is linear and through zero.
Here it is:

Max Patch
Copy patch and select New From Clipboard in Max.

Cheers.
