I have a harsher transition when OCS 1&2 are detuned to a certain degree on top of the -36 semitone for OSC2. But I don't really know what it is supposed to sound like
To me it sound as if SAWTOOTH has actually already elements of a very narrow PULSE hence the rather different character of the sound. I've no Oscilloscope here at the moment so I can not see if thats true or not. Therefore take this statement with a grain of salt.
