Audio is definitely editable. While generative audio is new I am hopeful that a host of interesting applications will emerge (audio2audio etc.) within its ecosystem. Promising signal separation (audio to STEMs) and pitch detection tools already exist for raw audio signals. If you want to force Stability to focus on symbolic representations (such as severely lossy MIDI) I hope you can instead first try adapting to tools that work fundamentally with rich audio signals. Perhaps there will be room for symbolic music AI and perhaps Stability will even develop additional models that generate schematic music, but please please don't sacrifice audio generality for piano roll thinking alone. LORAs will undoubtedly be usable to generate more schematic audio via the Stable Audio model -- I imagine they could be easily purposedly to develop sample libraries compatible with DAW (digital audio workstation), sequencer and tracker production workflows.
