Whats the difference between all these keyboard types???
It all depends on what you want to do with the instrument. A digital piano usually has just a few nice piano sounds and a few other keyboard instrument sounds like organ etc. The rest of the instruments you listed can produce the sounds of many instruments including drum sounds etc. If you want to be a “one man band”, these instruments can allow you to play many instruments at once. You still need to be a pretty skilled musician to do this though. Most workstations can also do arranging and vis versa. These instruments allow you to compose your own music. You might want to try some software like “Garage Band” before you spring for a expensive keyboard instrument. “Garage Band” is relatively inexpensive and it allows you to arrange and compose music.
