I feel the Analog Rytm a very nice standalone unit, pretty fun and a lof of possibilities. I think that is more straightforward than OT, so it’s nice to grab it and start to make some patterns pretty fast. You can experiment of course and resampling and making sounds using the double vco; samples or both. I really recommend it.
Off topic: Your idea of use velocity as modulation source is pretty convenient but i see it a little cumbersome. Why not Parameter Lock a bunch of steps to give it that kind of life instead of program the modulation page? I feel it more slow and not as precise as doing it by step and to your liking.
