Note: Results are reported in the form of mean ± sems (sem refers to standard error of mean), where s is a letter. Different letters within a column indicate significant differences (p-value p < 0.05) based on a Wilcoxon signed rank test.

Objective Evaluation Details: Each model generates 16 samples for each of 6 test pieces. Negative Log Likelihood (NLL) is computed by inputing the molody and accompaniment into the MuseCoco 1B model.

Subjective Evaluation Details: One piece cherry-picked from 16 samples of each test piece, resulting in 6 pages of questions. We collect responses from 22 participants (18 complete submissions and 4 partial submissions). For complete submissions, the average completion time is 16min 59s.
