If you're looking for a tool that uses AI to turn an audio file into synthesizer presets, MicroMusic is one of the most interesting options. This AI-based system turns audio samples into Vital synthesizer presets, automatically figuring out the best parameters for a particular sound. It's designed with a simple interface for musicians and producers, letting them turn an audio sample into a synth preset. MicroMusic is available as a one-time license for $100 or as a monthly subscription for $10, which includes unlimited preset conversions and future updates.
Another intriguing project is Beat Shaper, which serves as an AI music production assistant. Beat Shaper can generate beats, basslines, melodies and VST synthesizer presets based on your style, designed to increase productivity and get past creative blocks. It can integrate with digital audio workstations and can be controlled with fine-tuned text prompts or sliders. Beat Shaper is in an invite-only beta phase right now, but it's scheduled to be fully released in 2024.
For a broader music production tool, Soundry AI offers text-to-sound abilities and unlimited sample packs. It doesn't specifically generate synthesizer presets, but Soundry AI's generative toolset can help musicians quickly create new sounds and explore different styles. It's free to get started, though there's an optional Artist Partnership Program that lets you contribute to the AI model and add your own sounds.
Last, Fadr offers a web-based interface with a variety of AI music tools, including a SynthGPT feature for generating playable instruments from text. It's more geared toward other music production tasks like remixing, stem extraction and live performance tools, but Fadr can be a useful addition to your production workflow, with free and subscription-based options.
