I want to learn piano. Unfortunately, I don't have a lot of space in my room and on my desk. So I want to at least buy a mini-keyboard and learn piano basics with it. I also want to get into making loops and electronic music later on, so I guess a keyboard over a "real" piano is the right choice anyway. I know that a mini-keyboard is suboptimal and I can't play all songs with it, but to start off I guess it's enough.
So I looked up a few models and I found the following ones:
Korg microKEY 37 MkII
Midiplus X3 mini
Midiplus X4 mini
Arturia Keystep
I want to able to play basic chords and easy songs with both hands. Also, it would be nice if I could play without connecting to a PC, then it is easier to just practice and I can't get distracted. Unfortunately, I don't know anything about keyboards. Can you help me to choose one that fits to my needs?
