FeelYourSound has released MelodicFlow for Windows and Mac OS X. MelodicFlow is a MIDI performance and songwriting VSTi to create and play basslines, hooks, and melodies quickly. You will never sound off, as all your input is mapped to the right notes instantly.
The concept is simple:
There are also special black keys which will trigger the whole chord instantly. You can even transpose your notes by some octaves while playing. Find out more in the manual. See it in action for yourself:
