Question: I need a wavetable synthesizer that offers a rich and expressive sound design experience.

If you want a deep, expressive wavetable synthesizer, Orb Plugins could be the ticket. Orb Synth X is a serious instrument geared for sound designers and producers, with AI-created sounds, a relatively intuitive set of parameters and support for most DAWs (except ProTools). It's got presets and an upgrade path, too, so you can get the full sound design experience.

Another interesting option is WavTool, a web-based music and audio production tool that uses generative AI to help you work faster. It's got plenty of features besides synthesizing, like a multi-modal music chatbot and audio generator, but its customizable interface and support for VST & AU plugins means it's a good option for musicians who want to get creative.

If you're interested in generative tools, Soundry AI offers text-to-sound abilities and unlimited sample packs. That can be helpful for creating variations on a sound and exploring a lot of musical ideas. The service is free to try, but you can pay for more features through an Artist Partnership Program.

Last, Databass AI is an AI-based audio tool with some higher-level abilities like Text-to-Audio and Stem Splitter that can help you work faster. It's got a lot more general-purpose audio processing tools, but Stem Splitter and audio-to-audio manipulation abilities can be helpful if you want to isolate and transform different parts of a track.
