Doubt between 2 sound cards

Doubt between 2 sound cards

Good morning,
I am starting to alelstire my small desk for production, predominantly dance. I will not use musical (live) instruments but only pc, ableton, 1 pair of krk monitor, 1 large (mute) midi usb keyboard and 1 midi Novation Launchkey.
I am choosing between a Focusrite Scarlett 2i2 and a 4i4.
Why might I need a 4i4 in spite of the 2i2 which seems sufficient for me?
Thanks for any suggestions

I’d only grab the 4i4 if you ever want to stay flexible in the future for more in/outs to jam live or record but the 2i2 does sound like it packs enough for your current needs. There isn’t really a wrong choice here.

Your timing is pretty good too, the 4th gen just dropped.
