Korg's Opsix aims to cut down on and combat the confusion of FM synthesis with intuitive and accessible design features—features that also make it particularly excellent for live performance. This synth's onboard control layout is really clean and clear, featuring sliders for volume and level and six operators that change color from pink to purple based on what function they're set to. It comes loaded with 200 onboard presets and up to 500 can be saved. To help inspire your creativity, there's also a "randomizer" mode that'll make total random algorithms you can play around in.
