Poly Synth Distortion Help


    Dec 22 2006 | 11:24 am
    Hi guys,
    I am still trying to work on my synth project and have managed to get it working to a certain extent. I have managed to get it playing 4 different oscillator types and get amplitude envelope working.
    However the output seems very distorted when I play chords on my midi keyboard. I am not sure if this is a result of something I am doing wrong with the poly~ object or what ..? I have attached a clip object to the output with thresholds -0.99 & 0.99 but I seem to have very little control over the volume and this apparent distortion.
    Could someone have a little look and see if they can identify anything that might be going wrong with the patch.
    Thanks
    Freddy
    Main Patch:
    max v2;
    SynthPoly4 Subpatch:
    max v2;

      You should keep in mind that you are using 4 oscillators in your poly synth patch and the outputs of all of these add up and will already be distorted before it leaves the poly object.
      So limit the output of the polypatch to for example 0.2 (to be on the safe side).
      Hope it helps
      Grtz, Stan

      This is not true, Max is using 32-bit floating point internally, its not
      distorting before it leaves the poly~. But it will distort on leaving
      the DACs. You just need a gain~ before the your dac~'s.
