on rytm you have only chromatic mode, no scales, you can play on the pads 12 notes at a time, no way to fold scale like on the digis… but the pads are velocity sensitive, not everyone likes it though…
same process afaik, you can resample any track or incoming audio from dedicated inputs with a dedicated resample button, so yeah it’s pretty much the same.
btw, just to understand the shortcomings of the rytm I’d suggest walking through the feature request threads, you’ll get a pretty good idea what it can’t do at the moment and if there’s some dealbreaker for you in there, of course these are focusing only on the disadvantages, they don’t reflect what it can do, which is a lot!
(this one is pretty old so start somewhere from the middle)
