I feel like I've been hyperfixated on OpenMPT due to listening to .mod, .xm, .it, and .s3m, but how am I even supposed to tell if the scene is shrinking or if I’ve just fallen into some niche rabbit hole all by myself? It’s like everyone else moved on to fancy DAWs and I’m still here obsessing over hex values and pattern effects like it’s the 90s.

Oh and by the way, I'm 22.

I have no real hard data about this, but from my vantage point it seems pretty much alive. I have noted that the number of entries in the tracked music competitions seems to have gone down for the last years. But to say it's shrinking, I don't know really.

From my limited understanding I think it will be dependent as the scene moves across generations and platforms. I think trackers will stay for old system comps and just get absorbed into the workflow for modern ones, so not to entirely disappear

Can't speak for renoise, milky, fasttracker2 BUT, the OctaMED and Protracker scenes are thriving now in small pockets of the internet due to their limitations and quirkiness, even adventurous youth are picking up on it.

There's a split within that scene of older heads still making doskpop with ST01 samples and uploading it to "mod"archive.com (and yeah that's fine) and on the other side there's the PT1210 (mod dj'ing software) guys making underground dance music genres for DJ mixes.
A possible 3rd entry is also the compo heads making chiptune music and kb-limited stuff for.... yeah - compo's lol.

So yeah it's not dead in my eyes. I don't think the .mod .med and .xm formats will ever die. They were good back then there's no reason why they aren't still good.
