Someone mentioned you need a Kronos to do this kind of thing properly, but while of course the Kronos is one of the best board for seamless switching, there are even things the PA does better here. For example, using my video example of a split, you may find that when you change to a different RH sound (and have only a few octaves available for it), you might want to quickly adjust its octave. Simple on the PA, not on the Kronos (though you can ameliorate that by selecting a Kronos with more than 61 keys, if you can deal with the travel weight). PA is also better at being able to sustain a held sound through multiple patch changes. It's always something.
As does having just one board vs. multiple boards, or having a board that has sound set X vs. sound set Y. For choosing sounds on the fly during performance--even though we're talking about scenarios where you may not know what you'll need next--how many sounds do you really need to be able to choose from on a whim? I demonstrated the approach I did because the "challenge" was "no advance setup." But with very minimal advance setup, you could create a User bank with, say, 32 commonly used favorite sounds that you know won't glitch (I picked 32 for this example because 4 pages of 8 means you can get to any sound with no more than two taps, but you could certainly go beyond that if need be)... that would probably get you through just about any improvisational or similar scenario where you can't predict what sound you'll want to be switching to at a given moment. In a situation like that, you probably don't need to be able to pick any of 10+ Rhodes and 10+ Wurlis at a moment's notice, one of each is probably sufficient. A variety of 32 common sounds would handle most common songs that don't need something very song-specific. And this setup would have the advantage of putting those 32 favorite sounds within two taps, whereas the "unrestricted" method can still require more than two taps to get to the sound you're looking for.Korghelper wrote:arbitrarily restricting yourself to sounds that you know won't glitch restricts your choices.!
Going back to the LH bass scenario, even in the Kronos, you'd really want to advance-setup a selection of "common things I might want to pick on the fly." The Kronos is not really setup to let you pick ANY right hand sound at any time unrestricted, again the PA is better here. Okay, the PA might glitch in some cases, but Kronos is worse. If you use the Quick Split feature, every sound change will create a hard cutoff... even just changing your RH sound will silence your LH sound! So instead you have to go to a LH bass Combi and go to the Edit page of your right-hand sound. Then at least you can freely pick right hand sounds without cutoff and without glitching your LH bass... BUT this method doesn't bring in effects at all! (There is a "Copy From Program" option that brings in effects, but everything--even the sound you're not changing--cuts out, among other issues.) Again, there's always something...
