I fuck with chord keys
Cause the sound lasts longer, bass drummer song
And a hi-hat made of plastic, nigga's sound is elastic

from Tyler The Creator – Jack and the Beanstalk Lyrics on Rap Genius

Meaning

Tyler’s beats often feature heavy chords; apparently he likes their deep, lingering sound. He also likes fairly deep bass and snapping drums

Also, Tyler actually fucks with KORG keys, coming from popular KORG synthesizers which he uses throughout all of Bastard.

KORG presets have a long release, meaning once he lets go of the note(s), the sound continues to drift on, giving him a certain vibe.

his hi-hats are being triggered from a plastic MIDI keyboard most likely, and his sound is elastic due to the interchangeable/customizable aspects of MIDI notes in beat production.
