i try to build a meter device that show me the output of four tracks. at the end the whole meter is meant for open in a floating window, but that is another story.
at the moment my problem is that i have no correct displayed meter. it looks like to slow and not right scaled or something but thats only a assumption.
i used the live API to observe the signal from a track and i get a signal with a value between 0. an 1. . the big problem is, that this signal is not correct interpreted by the meter objects (max meter, live meter). so i tried to translate the signal with this math formula: expr 20.*log10($f1) do get a db signal, but still it doesn´t work proper.
another thing is, if i turn up the volume on the observed track the meter have a strange behavior. a similar thing happens if i turn the volume down. the meter raise extreme and show a consistent peak.
I tried my best to find a way by my self but i´m not e very experienced max/msp user but hopefully you can help me. basically i need this patch for a current DIY dj 4 channel midi controller project for ableton. at the end of the day the meter a displayed in an external 7" usb monitor which is mounted in/on the controller. every observed meter correspondents to a physical channel on the midi controller to get a better visual feedback in your dj set. hopefully you get the idea of my patch and somebody can help me.
if you need any further information feel free to ask me.
