One music sequencer for all major platforms, desktop and mobile

I downloaded this and played around with it a little.
I’m a little skeptical of something that ditches traditional music notation for piano roll, doesn’t offer any ways to reorganize sections of your song, and then gives you a bunch of tools for key signatures, modes, polymeter, and microtonal music. I’m trying to think of a programming analogy—it’s like checking out a new programming language that has dependent types, higher-kinded types and monads, and a borrow checker, but no strings or integers.
It’s really easy for those of us with analytical, mathematical minds to go diving into the more esoteric parts of music theory. Set theory, microtonality and alternative tuning systems, esoteric scales and cataloging all these different scales—but then you fuck up the basics or miss them completely. I noticed that the “major” scale is only available under its more esoteric name, the “ionian” scale, and then there are five different versions of locrian to choose from, not counting the ones outside 12-EDO.

Even with all these esoteric features, there is no such thing as, say, Eb. There is only D#. As programmers, we really want to normalize all our data so that it’s represented in exactly one way, but as a musician I like having both sharps and flats around. They’re convenient and make the music easier to read.
This is a neat tool for playing around with scales and tunings, but it seems like absolute hell to try and write music this way.

Back in the day there was a very nice and simple little MIDI sequencer for X-Windows called something like Seq24 that I used a bit on and off. Of course there are much more complex music software that also happens to have MIDI-support (LMMS, Renoise, ...) but I liked Seq24 because it only did short MIDI patterns and had quite good GUI (holding down various modifiers and using the different mouse-buttons to do most edits).
Searching I get a link to a URL that looks like it could have been the Seq24 home page, but Firefox throws up a security warning for that domain. There is also a hit for this project that claims to be based on Seq24 and that has commits as recently as a few days ago, so maybe this is worth looking at:
