See my other post too please.

Yes i want to generate a unique melody using QWERTY Keyboard input.
And I waould like to use my Roland PC-200 MK II because it feels much better than the PC Keyboard.
but if I have to, then the PC Keyboard it is.

I did this back in 1998 and some in 2005. Now I have all the time in the world (lol) to play around and have fun.
Remember i do not play any instrument and barely read sheet music.
Just enough to be able to see what is happening.
