Sample pack that goes with the video, 88 samples, perfectly looped where appropriate. All in "C".
Try the techniques shown and also the pitch slide + chorus effect on some of the non-Juno style sounds too, e.g. the sync sound, for interesting effecting.
Note: if you don't have Serum FX, try another "dimensional chorus" like Valhalla Ubermod for example, which I think might even be better. Start on the 8 tap setting and play with the settings until it sounds good (careful not to go overboard though!).
