Cool topic, interested to see what comes up. I am always in search of the ultimate sequencer in Ableton/M4L
As mentioned already the Rene clone “Snake” is interesting, and I just checked now and it seems there’s an new version available. That’s cool as the previous one had some bugs. The ones inspired by the Roland System 100 185 sequencer (there are a few) can be interesting. Though don’t really suit my workflow.
There’s the Polyrhythmus that seems popular. I messed around with a bit never got hooked on it.
I find the new Melodic Steps device in the Creative Essentials pack from Ableton disappointing, kind of simplified Mono Sequencer with bugs attached
I was hoping on an update to the Mono Sequencer which I always find myself going back to as being the most creative, though it also has some bugs and the GUI has some issues since Live 10 came out.
I think a modular approach with Ableton is also useful, a sequencer combined with some M4L devices adding modulation. I also find Ableton’s native MIDI effects to be very useful in generative situations, in particular the Velocity device, simple but also powerful.
