I was experimenting with a sound I had set up for a rock organ sound, which combines two of the organ sounds on my keyboard, and I cranked up the filter and resonance all the way to see what would happen, and I got this crazy B3 sound, complete with the key click! Check it out! The first file has more single notes, while the second file has more chords. Each is about a minute long.

On the PSR-E433 through E463, this should all be similar, except the voice numbers are likely different.
Of course, you can experiment with different settings of the pan and reverb to get more spacious effects. Reducing the filter cutoff a little can mellow out the sound somewhat, but if you bring it down too far, you lose some of the key-click effect.
