filtergraph~ + cascade~ = clicks ?


    Dec 28 2011 | 9:10 pm
    Hello, I am experiencing clicks when changing the data of a filtergraph~ plugged to a cascade~ controlling audio in real time. Same situation as in the helpfile of cascade~ with ADC as Source. Was working great with Max5... Do you have the same ? Thanks for your help.

      Thanks Christopher, this is helpful but the weird thing is that it's working without any filtercoeff~ or line~ with MaxMSP 5.1.9 I just opened cascade~ helpfile in MaxMSP and Max6 and they don't behave the same way. With the same audio settings, changing filtergraph~ in the following patch is very smooth with MaxMSP 5 and heavily clicks with Max6...
      Is it because of the multiple DSP chains ? If I could avoid to add line~ everywhere that could save me several hours of work...

      I have a similar problem of clicks since Max6, but in my case, the problem comes from CASCADE~ and neither from filtergraph nor any coeff changing .
      Each time the coeffs are sent to CASCADE~, it creates a click, even if the coeff are the same than previous, as in the enclosed patch : you'll hear and see it at every bang sent every 500ms.

      indeed, it is [cascade~], and it is a bug known by the developers afaik. happens with [filterdesign] dynamic updates too. sadly we just have to wait. no workaround.

      just wanted to say the Max 6.0.7 update solved this issue -on my side at least
