Looking for keyboard display software

[warbread]

I've been looking for a specific sort of software and to no avail so far. I'm hoping someone here might have an idea.

I'm wanting to make some screen casts that will show a piano that will respond to what I play on my midi keyboard. When I play C3, I want the C3 on screen to respond. Note that I am not looking for a virtual midi keyboard.

The closest that I've found to what I want is in FL Studio, but it's too small for me, and I'd prefer an open source program if available. If anyone has any ideas, please let me know.

Have you tried the virtual keyboard in ZynAddSubFX? You can use jack to connect your midi keyboard to zynaddsubfx and then you should be able to watch what your playing on the virtual keyboard. It's rather small though.

I wish. Zyn was the first thing I tried, but the keyboard doesn't respond to midi input... unless there's something wrong with my install, that is.
