If you want a music production tool that works within your DAW and lets you edit samples within your project, Samplab is a good option. The AI tool lets you edit notes, drums and chords in polyphonic audio, adjust tempo and key automatically, and split audio into different stems. It's a VST3 and AU plugin or desktop app, with basic (free) and premium options.
Another option is TwoShot, which offers more than 200,000 samples and an AI music sampling service. It comes with a natural language search engine to find samples, an audio sampler plugin for multiple DAWs, and an online jam studio to turn ideas into songs as fast as possible. The service also offers automated licensing so you can clear samples and release your music.
