For the sound, use two detuned saws, both with the PWM turned up, a bit of vibrato, all at slightly different LFO speeds. Then close filter 1 with maybe a bit of resonance until it goes from “trance lead” to “mellow pad”. You might want to add some subtle LFO to the filter cutoff. Also, you probably want to set the tracking (close) to 100%.

You can make envelopes rest to zero by choosing a shape with a dot at the beginning; see the manual for details.
