With no reply here yet, a general recipe that covers most big trance drops:
1. Lead: a supersaw built from 2 or 3 detuned saw oscillators (7 voices each if your synth allows), detune around 30 to 40 percent, with a short attack and a slightly longer release. Layer it with a plucky saw an octave up for definition.
2. Sidechain: duck the pads, lead and bass from the kick so the groove pumps. A 1/4 note volume shape works if your compressor feels too subtle.
3. Bass: an offbeat rolling bass or a 16th-note pattern, kept mono below about 120 Hz.
4. Build into it: a white-noise riser with a filter sweep, a snare roll that speeds up, and a high-pass on the whole music bus that opens back up on the downbeat.
5. Space: a long reverb and a 1/8 dotted delay on the lead, both sidechained or ducked so they swell between notes rather than washing it out.
6. Contrast: drop everything for a beat or half a bar before the drop lands. The silence makes the impact feel bigger.
