How i can achieve this chord sound with renoise?

I am talking about the beginning of this song (0:00 to 0:10) linked here seventeen - YouTube

I’m not sure but did the author made 2 tracks with sine wave chords playing alternately and added a distortion + some other stuff to the second track? Sounds like it at least for me

sounds to me like a simple additive sine pluck (with maybe just a few harmonics) going through delay and reverb, parallel processed with bit reduction on one channel
