Clicks when changing Circular Plate-Free pitch or radius

Hello,

I am using modalys~ in Max6 6.17 OS X 10.9.2. I am using the modalys~ object inside poly~, so there are a few instantiations. The plates just have force applied to them sometimes to make the sound.

When my patch changes the radius or the pitch a click is generated. I have tried anti-click envelopes and thispoly~ muting similarly to the example in the Mlys.Overview Polyphony example. I see (and hear) in the Controllers example that it is quite possible to change the pitch or length of the string without clicks.

Would the use of a signal input for the force make a difference? Is the Circular Plate-Free different in some way that means it cannot be changed like this?

My patch is extensive, I may prepare an example patch later to illustrate the problem.

Thank you,

Best,

Simon

Pitch, radius or length ecc. are main physical parameters: the objet is recalculated every time you change one of them…so it’s normal to hear some clicks when you ask for a new pitch and at the same time you instantiate the instrument. It’s one of the main problems of using modalys in realtime.

Clicks are less perceivable in one-dimensional models like string, but they are prominent in two-dimensional models like plates

Okay. Thanks for the clear answer. :slight_smile: I will keep this in mind in the future.

Hi,

If you need to change the pitch of an instrument in realtime without clicks, you should try the mlys.melt-hybrid object. It’s a way to interpolate between two instruments which can have different material or pitch. Here is an example on how to use it with plates. In a future release, you will also find a pitch bend function which should be more efficient…

Best.

Jean
