This question already has an answer here:
I bought a second-hand MIDI controller keyboard recently hoping to be able to plug it in to my Windows laptop and play away. It has not been as easy as I hoped, and I have not been able to get my laptop to make a single sound so far. (I have tried several solutions which were either too complicated or just did not work.)
What I am looking for is a simple software package that will allow me to play my MIDI controller keyboard, like a simple standalone keyboard/piano. I don't need recording/editing/etc. (at least not at the moment, I am still a beginner).
What I do need, is for the software to be free, and the instructions to be clear and easy to follow for an absolute beginner (for example, I do not understand terms like VST and DAW that I have seen elsewhere).
I found an equivalent answer for Ubuntu, and I would like a similar answer to allow playing it on Windows: https://askubuntu.com/questions/147052/step-by-step-to-run-a-midi-keyboard-input-device-12-04
