Unofficial/intermediate paper deadlines / feedback period

Are there any unofficial/intermediate paper deadlines besides the two listed on the 2025 call for submissions page (1/29 title, abstract and author lists due, 2/5 final submissions due)? I’ve seen a paper feedback period referenced in some older NIME papers - does this begin before or after February 5, the CMT paper submission deadline given on the NIME homepage? Apologies if I should know this already.

The two deadlines are the final deadlines for articles to be considered for review. The authors can submit their final submissions on Jan 29 if their manuscripts are ready or create the initial submissions with title, abstract, and author details by this date and be able to edit and finalize their submission with the completed papers by Feb 5.

After Feb 5, it is not possible to create any submissions on the paper track. After this deadline, the review process starts and the authors will be notified of the reviewers’ accept or reject decisions on April 2.

I hope this clarifies a little bit more. Please, let us know if you have more questions.
