Sorry if I don’t see why your post is so special compared to (for example):
or any of the other Digitakt vs. Octatrack topics:
https://www.elektronauts.com/search?q=digitakt%20vs%20octatrack
Of course the Digitakt is (very) limited compared to the OT.
- 1 LFO vs. 3 LFOs
- mono vs. stereo
- OT: much more effects
- OT: dynamic (re-)sampling
- OT: crossfader and scenes
- OT: song mode (aka Arranger)
- OT: more inputs and outputs
- … and so on …
And if you want a detailed comparison then examine the manuals from the elektron support page side by side.
