I'm using ofxFilterbank in a scene (through ofxAppUtils). When I'm moving through scenes, my app crashes on the filterbank scene unless i've stayed on the scene for about 4-5 seconds. But I don't get a crash if I comment out the contents of void ofxFilterbank::exit()

//    for (int i=0; i<channels; i++) {
//        for (int n=midiMin; n<midiMax; n++){
//            if (fdata[i][n]!=NULL ) free (fdata[i][n]);
//        }
//        free (fdata[i]);
//    }
//    free (fdata);

If I only comment out if (fdata[i][n]!=NULL ) free (fdata[i][n]); then I'm allowed to go past the scene without pausing but the app immediately crashes the second time I go to the scene. Any ideas what could be going wrong?

I'm using ofxDatGui but could also use ofxGui. I'd like to have sliders control variables such as threshold, as per your vimeo example. Sorry, this is probably very simple but I'm a beginner. Any tips?
