I must be total idiot, as I do not know how to make that technique without hardware MIDI controller to work. Where Jim explains that he (if he did not have a Midi hardware controller) '.would assign the MIDI learn function to one of the 3 virtual knobs found on a standard MIDI track in Logic (the ones labeled Freq, Chor and Rev), and then turn those virtual knobs with the mouse while in record.' Know that Stylus RMX has more than 20.000 parameters.
