HEY mr. WESTWOOD!! or anyone else....

i just made a small discovery (you probably already know this): the filter can be a synth.ressonance: 100% creates self-oscillation,i.e. sound.cut-off filter decides tone, 1 semi-tone changes per step when you control the cut off with the jog-wheel in the fx-edit window.the sound is totally clean, and at a high pitch its perfect for those classic west-coast-rap synth melodies often heard from dr.dre and the like back in the day.so what i wanna know is the following: is it possible to control the sp808s cut-off filter via the keys of a MIDI keyboard ?
thanks in advance to all who might answer.peace.
brage.
