Changing set_precision in Max

Hi there!

I have been working in making a signal network inside of an expression controller.
I discovered that there could be an issue with the set_precision command.

Look to the adjoint patch. First a signal network using controllers, then the an identical patch inside an expression.
The first is clean, the other noisy and unclean. Changing the set_precision of the second example to ‘double’ helps.
Any explanations why 64 bit should make it better? Does the “@precision” of Mpdalys~ overwrite the scripts precision mode?

Two other (related?) issues:

  • Changing parameters values of the expression examples makes zipper noise. Why is that?

  • The range of the depth parameter of the first examples is different and quite big compared to the second examples.
    I thought they should work the same (= be identical). They dont. Any ideas why?

Hi Hans Peter,

This will be investigated in due time.

Best,
