On the PSR-E433, XG-LITE Voice #566 is Soft Whirl. This is Voice #597 on your PSR-E463. I take it that this is probably meant to mean "Soft Wurly", but is Yamaha's "code" for avoiding "infringement" issues. When I try it "as is" on my PSR-E433, I get something that might sound remotely like a Wurly, but what is obviously missing is that typical tell-tale Wurly "bark" when you really rap the keys. Maybe that is what is meant by
Soft Whirl - no
bark ! ! ! The required velocity switching for it is just not part of the sample. I spent a couple hours last evening experimenting with various settings of the Cutoff and Resonance knobs on it, but could not even come close to anything that sounded at all like a believable velocity "bark". I know what you mean. On my Casio CTK/WK-6000/7000/7500, I was able to get a very reasonable simile of Roger Hodgson's Wurly sound on Supertramp's "The Logical Song", but try as I may, I just can not do it on the E433. If you want to try, I suggest, at least, starting with Voice #597. As suggested above, you might want to try layering Voice #597 (or other epiano voices) with various other epiano voices, or possibly even with one of the acoustic piano voices, but if you do that, you will need to shorten the release time of the acoustic voice way up. The release time of the average acoustic is way too long to simulate a Rhodes/Wurly "reed" type instrument. My fear in trying this on an E series board, is that you will very quickly run out of necessary simultaneous effects.
Hodgson split the output of his Wurly, and sent half to the sound board completely dry. The other half, he sent through a standard guitar effects chorus pedal, adjusted the amount of chorus at the pedal, and sent that on to the sound board. Then, at the sound board, he adjusted the levels of the two signals until he got the overall sound he wanted. In listening to a lot of Supertramp's songs, I don't think "The Logical Song" is the only place he did this. It's just the most noticeable. It is a lot of fun to add a little additional effects, like phasering, flanging, or delay to that chorused signal with a little reverb added to the overall mix.
https://en.wikipedia.org/wiki/Wurlitzer_electric_pianoThe Wurly sound in the above link has just phasering added to it. It is NOT an example of Roger Hodgson's "Logical Song" Wurly sound scheme. What is important in that link is the mention of the fact that, if you want to start with basic "raw" sounds, the Wurly sound is primarily a saw-tooth wave, while a Rhodes' is more of a sine wave.
