I am looking for some professional help here and would appreciate any input you may have.
I am shopping for a keyboard for my house. I am not a musician, this is just my hobby. I am a beginner who is learning the keyboard, so I have many questions that I need answered before I buy a keyboard.
I've been researching for a long time, probably saw every singe (kidding) video on Youtube

I am looking for either 73 or 76 keys unit. 88 is too heavy and 61 is too small. I also like a feel of a 76 key units vs 88 which have a piano-like feel.
My questions are:
- What is the difference between Workstation, Arranger and Synthesizer?
- I will not be recording music. I want however the ability to play midi files (sequencer??).
- I have been looking at several models of korgs:
a) Korg M50-73 (love the touchscreen + lightweight)
b) Korg TR76
c) Korg X50 (I wish it had 73/76 keys)
d) Korg PA500 (I wish it had 73/76 keys)
e) ....Roland Juno
- Is it suitable for a home use to get 61 key unit?
- What is the advantage/disadvantage of 61 vs 73/76 vs 88 keys piano?
I can afford any of these, but if the extra money is unnecessary I'd rather not spend it.
This is going to be my first keyboard, so I don't want to spend 90% of my time learning its programming abilities. I want to play; however, I want to buy something I will not outgrow in 6-12 months when I actually start playing way better than I do now.

I will not be playing sonatas and other classics all the time, so I am not looking for a 88 key hammer action keys.
Thank you in advance for any information you can provide.
Best regards,
Karen
