PC Keyboard or MIDI Keyboard?

I'm making a synthesizer in my electronics class and I have 2 options for how I can approach it.

  1. I use my midi keyboard, which I would be more satisfied with, but I wouldn't be able to work on it during class.
  2. I use a library to use a PS2 keyboard as the input device. This would be easier to do and I would have more time to work on it, but the quality and usability would be greatly diminished.

What do you think I should do?

How about both? i.e. Write a little utility that converts computer-keyboard strokes into MIDI commands. Then, maybe a hardware-switch to switch between the two setups if you can't detect what's being used automatically.
