Took literally seconds to make. Quick note, which is something we've just learnt with Subtractor (and going to try with other synths too) - Legato on and pitchbend with portomento time can actually affect the speed of the pitchbend
For example, have the porto to zero, and pitchbend in instant and follows every nuance of the wheel. Now if you increase portomento, the pitchbend rate changes so you can actually stretch out pitchbend time, which is pretty damn cool and going to be some fun to now humanize pitch bending a bit more simply by adjusting both the wheel (the level of pitchbend) and the porto (the rate of the pitchbend)
Another tip - if these settings are a little too sharp, add the 2nd filte on Subtractor to smooth out the top end. It's not far off and in a mix you could get away with this being your 'own'
EDIT: will look at this patch again, and do it so you shouldn't need the pitch bend, the MOD ENV on Osc 1 pitch could be enough to set it up. Will take a look later again today
