I forgot too mention too, you may or may not know this, in some songs that use it, the sound's got more of a slide too it between the notes, like a pitch bend. The effect's called portamento, on the NN-19, Subtractor and Malstrom the knobs on the left of the unit about halfway down. Just adjust this to taste, so if you're trying to make it sound like a certain song and it's not sounding right, you may just need to adjust the portamento.
