This page contains the analysis for the paper M. Pettenò, A. I. Mezza, and A. Bernardini, "Conditional Diffusion As Latent Constraints for Controllable Symbolic Music Generation", in Proc. of the 26th International Society for Music Information Retrieval Conference (ISMIR 2025), Daejeon, Korea, Sept. 21-25, 2025.

The code of the paper is available here. All the MIDI examples in this page are generated by our model LC-Diff.
