filtergraph display mode

    hi
    I'm using a filtergraph~ in cascade mode (5 filters) to create various different filter presets. I'm storing the presets as lists of filter coefficients from outlet 1.
    I also want to be able to load the presets back into the filtergraph to further edit them, but every time I send parameters to the filtergraph it switches into display mode. I've looked to see if there's a message (or message per filterbank) to reset the banks to peaknotch, but can't seem to find one that'll do it. I can send [peaknotch] to the filtergraph, but that only sets the first filter to the right mode.
    Have I missed something obvious? Or obscure?
    While I'm here - I was also trying to make a 5 bank filter that morphed between random settings, but I don't know enough about filters to know what ranges of parameters would make sense. (Ie I wanted to use random number generators to send filter coefficients to filtergraph). It may well be that this won't actually work - but just in cases - are there ranges of values that I could randomise that would produce meaningful results in biquad?
    thanks

      Bonjourno old thread.
      I have a similar enough problem to bump this, I think.
      I'd like to 'link' filtergraphs, but for some reason the one being sent coefficients goes straight to display mode, meaning I can't change it's frequency.
      I have tried to illustrate this below.
