The more complex you make a synth tone the less capable it is melodically. This is a fact.
Why then do all the synth leads on even workstation keyboards and music from metal keyboard players, to video game soundtracks, to Yanni's lead tones almost all sound essentially the same? Usually pulse or saw wave with pitch bend, portamento and lfo for vibrato, maybe a bit of distortion?

Spoilers: It's because it's the sound that most-closely emulates the play-ability and timbre of string instruments like a guitar or violin, and are seriously about to tell me this doesn't sound cornier than using one of the acoustic instruments instead?
