Upload a piano score MIDI file and let the Pianist Transformer render it into a more expressive performance MIDI.
Two versions will be saved:
• Raw Performance – directly generated by the model
• Editable Version – aligned with the score using our Expressive Tempo Mapping algorithm
If mapping fails, only the raw version will be returned with an error message.
⚠️ This is only a demo running on limited compute resources. Please do not upload long pieces — we recommend clips shorter than 1 minute.
