my most recent music has been focused very much around Rytm and hardware synths being processed via software. often faster tempo and occasionally noisy & dirty and dynamic, though i often delve into ambient and techno and acid-tinged areas as well. you may be into it if you like Venetian Snares, Squarepusher, Autechre, Aphex, and others of that type.
over the past few weeks I’ve put out about an hour’s worth of music through a couple of EPs, the most recent is linked below…
thanks for giving them a listen 
I’d like to know more about your setup. What else are you using with the Rytm?
i love improv stuff as well, all of my released Rytm-based stuff is improvised to a large extent (usually swapping between patterns, muting, mixing sounds in and out, effects, etc., sometimes ‘writing’ or editing on the fly as well though) i always think of them as jams really.
I’ve wanted a TG33/SY22/SY35 for years and I’m jealous.
drums are all Rytm mk1, and the synths are mostly Analog Four, with various other bits of synths here and there… I’m sure there’s some Pulse 2 and probably some Evolver in there in spots.
