Welcome to the forum. As I don’t know Harmor I can’t help you here. Falcon does not have a spectral oscillator so achieving identical sonic results as in Harmor might be impossible. For edginess, check the available distortion modules on keygroup level (per voice) and apply a random modulator to various parameters so that with each new note played the parameters are changed randomly (does not work on layer/program level). Maybe the additive oscillator comes closest to the Harmor sound.
