Yeah, it's typically a Sawtooth wave or Sine wave to create that "Gangsta whine" type lead. It's hella easy to create with VSTi synths like Minimoog V, Minimonsta, MinimogueVA. Basically any synth that simulates the classic moog synths. It's a monophonic sound. So sometimes bass synth sounds can work to create this whiney funky synth sound when played at higher octaves. You can even give the sound some LFO modulation to give it more of that funk.
