I was looking at some midi keyboards, I already have an Akai MPK Mini MKII
It's a 2 octave keyboard but It has an extra key off the right side C,D,E,F,G,A,B | C,D,E,F,G,A,B | C
What's the purpose of that extra C key? Couldn't they have removed it to make the dimensions smaller?
While there are keyboards like this M-Audio Keystation Mini: It has two octave of keys without the extra key. Are these just design decisions?
Would there be any benefits/drawbacks to having that extra key as in the Akai device?
