This, so much. One of the concepts that's common in synthesis tutorials - the envelope - is shown as having 4 parameters - A, D, S, and R. In the XP30, this is split up for the sake of flexibility, using Time and Level parameters. You have to basically rewrite anything showing "set ADSR like this" into "Rolandese". All tutorials assume that you have a synthesizer with an interface that's laid out before you, but on the XP30 you'll have to paint the hallway through the letterbox, so to say.
The sound in the start could be achieved by various means; if all you have is the XP30, initialize a patch. You can choose a dull saw wave as Tone A. Cut it down further with a lowpass filter. Then, assign an LFO to the amplifier of that tone, and choose an upwards saw wave, and a low LFO rate. Add reverb.
The actual sound might be made with say, sidechain compression, but for all intents and purposes using an LFO should result in something similar.
I've owned an XP30 for over a decade now, and while I understand it in terms of synthesis it's just not worth to spend lots of time on patch design. Various other synths are equally flexible and a million times easier to work with.
