I actually just released a new M4L “sequencer” today called ACDGEN.
It’s not a sequencer but a 16th note / acid-style bassline / melody generator. I’d say it fits within @maxijazz’s wish for something semi-generative. I designed it based on my experience playing live sets for the past years and, while it’s inspired by other devices such as Skinnerbox’s STING, it includes a bunch of more advanced features (7 different algorithms, automatic pattern variation, pattern shifter, export to midi clip, and more).
I definitely developed it with live performance in mind but it’s really useful for music production as well.
Here’s the blog post I wrote that constains all the info about it: http://spektroaudio.com/blog/2018/8/23/acdgen-10-is-now-available
