Here are the best free and cheap Funk, Disco, & House drum kits, sound packs, sample kits, chops, vocals, soundfonts, and presets for FL Studio, Sylenth, Kontakt, and more!
CHEAP SOUND KITS (AND COMPLETELY WORTH IT)
What I've learned in a decade of producing: you can usually get drums for free, but you're going to get better quality sounds and presets if you pay for them. It's what the producers who are actually making money off their instrumentals do. Better sounds=more sales
In short, invest in your sounds, but you can get the drums for free.
