I'm not sure what Hensonn uses to make beats, but I use FL Studio 20. If you want a good place to start with Phonk try find some 808 and 909 drum samples. the 808 cowbell is what gives phonk that sound you probably think of. For this track I think he used a Reese Bass for the bass. For the lead melody to get that slide sound you'll want something with a lot of portamento. I'm not sure if that helps, RU-vid has got a lot of great tutorials. A lot of my sounds I get are from Zen World and Splice. If your looking at getting into sped up or slowed tracks I think Audacity is still free, and you can do that on there.
