'Tickle-the-Ivories' Keyboard

Sometimes I like to compose this and that on my cheap Casio synth and port it over to the computer for posterity. Being somewhat of a keyboard afficiando, I've often been frustrated by the lack of well-laid out controls; when I want to add an effect or change sounds, for instance, I really don't want to have to take my hands off the board and hunt around in some menu, operate some thumbwheel, or punch even a large button.

What I want are smarter keys.

1. Wiggle-sensitive keys that respond with a bit of pitch-bending vibrato, like any good violinist will produce. I think this option alone would easily add some human depth to the still-too-robotic synth sound without being as laborious as your typical song-editing session.

2. They would also sense at what location on the key you depress them and adjust the sound accordingly to some programmable variable. Thus, depressing the keys further up on the board might result in a more distant or tinny sound, while hitting them down closer to the edge produces a fuller sound. A sliding action might produce 'fret noise.'

3. A few infrequently-used keys, like high-b natural for instance, could be designated as 'program' keys that run macros or navigate through pre-selected options.

And finally, could I have the keys in red and silver? I'm getting bored with the whole ebony / ivory motif. At least reverse the colors.
