make your own patch. Set glide/portamento to as slow as it goes, then set your lfo to control pitch and maybe filtercutoff or that type of thing. Then turn the lfo dial to slowest. Also press lowest key, or where you want to start your build. Then press the highest key and have the pitch slowly climb smoothly between notes as you increase the rate of the lfo by turning the knob. This method works great. It's called using your synth. If you can, use a real piece of hardware, as vst's come off sounding plastic.
