Performer, Stepper or LFO?

[Joakim95]

Hello, I have been wondering for a while how to make the high pitch that starts at 1:14, sounds like it's low pass filter and not so much cutoff at the same time as a kind of knife party synth.

Please help!

Thanks

Whoops, forgot to change the header to something else, first I wondered if the wobble at 1:14, 1:15 was Performer, Stepper or LFO in this song.
