Personally, I have little interest in typing a text prompt and getting a complete song as an output. However, I will gladly pay serious money for a tool that interactively collaborates with me in a granular, iterative process of generating, adjusting and mixing individual instruments and sections toward a finished multi-track song project.<p>Allow users to creatively engage by providing suggested starting places in the form of BPM, key and chord progressions or as brief audio and/or MIDI sketches. For example, let me give the AI a simple sketch of a couple bars of melody as MIDI notes, then have it give me back several variations of matching rhythm section and harmonies. Then take my textual feedback on adjustments I'd like but let me be specific when necessary, down to per-section or individual instrument. Ideally, the interface should look like a simplified multi-track DAW, making it easy for users to lock or unlock individual tracks so the AI knows what to keep and what to change as we creatively iterate. Once finished, provide output as both full mix and separate audio stems with optional MIDI for tracks with traditional instruments.<p>Targeting this use case accomplishes two crucial things. First, it lowers the bar of quality the AI has to match to be useful and compelling. Let's face it, generating lyrics, melodies, instrumental performances and production techniques more compelling than a top notch team of humans is <i>hard</i> for an AI. Doing it every time and only in the form of a complete, fully produced song is currently nearly impossible. The second thing it does is increase the tangible value the AI can contribute right now. Today it can be the rhythm section I lack, tomorrow it can fill in for the session guitarist I need, next week it can help me come up with new chord progression ideas. It would be useful every time I want to create music, whether I need backing vocals, a tight bass riff, scary viola tremelos or just some musical inspiration. And nothing it did would have to be <i>perfect</i> to be insanely useful - because I can tweak individual audio stems and MIDI tracks <i>far</i> faster than trying to explain a certain swing shuffle feel in text prompts.<p>Seriously, for a tool anything like what I've described, I'd be all-in for <i>at least</i> $30/mo if it's only half-assed. Once it's 3/4-assed put me down for $50/mo - and I'm not even a pro or semi-pro musician or producer, just a musical hobbyist who screws around making stuff no one else ever hears. Sure, actual music creators are a smaller market than music listeners but we're loyal, not as price sensitive and our needs for perfection in collaborators are far lower too. Plus, all those granular interactions as we iterate with your AI step-by-step towards "great", becomes invaluable training data - yet doesn't require us creators to surrender rights to our final output. For training data, the journey is (literally) the reward.
