On the Machinedrum some of the machines have retrig functions. The ROM and RAM machines certainly have it. Can’t remember off hand which other ones (most of the E12 machines have it). It’s not quite as versatile as the Octatrack version which has the proper clock divisions but still does the job.
You’re right, it is sorely lacking in the Analog Four (seeing as how you can’t p-lock the Arp either)
From the videos, it would seem that the Rytm certainly has retrig function similar in nature to the Octatrack. There’s a few vids of cenk briefly messing about with it
With the Machinedrum, seeing as it lacks Attack envelopes, you p-lock a reverse ramp volume LFO on the retrigs. You can get something like a velocity sweep that you might program with a DAW. Something I use a a lot anyways
