Hi Sullykin — Hx Works here.
Here is an eight-bar self-initiated piano A/B study with editable MIDI:
https://hxsworrk-lab.github.io/ui-motion-study/piano-phrasing/
The second version preserves the melody while changing accompaniment, dynamics, articulation, pedal and tempo. This is code-authored MIDI with a rendered piano, rather than live piano performance.
My reference rate is US$25/hour. I am available to review one short piece asynchronously (China, UTC+8); the trial’s fixed scope, total fee and delivery date would be agreed before work starts.
How long is the trial piece, and do you want revised MIDI, rendered audio, or both? A public or redacted reference is enough for the initial scope discussion.
