I really don't have any need for Analog Lab, Pianoteq or the UVI. I have an excellent XV-2020 with a lot more useful sounds on it for live gigs...but I'm finding that the Keylab 88 may not be as appropriate as I thought at first. I was previously using an M-Audio Keystation Pro 88 to control the XV-2020. It has the capability of up to 9 banks and more than 17 user-definable buttons that are tied to each bank. This means that I can program the Keystation Pro 88 to tell the XV to almost instantly call up 153 of the hundreds of system & user presets.
If I understand correctly, there are only two possible banks on the KL88, and I can find nothing that tells me which buttons are tied to the banks. Also, it seems that the 10 buttons for "Edit Parameters/Snapshots/Switches" can be configured to "Program Chg" but the 16 tap pads can be configured for "Patch Chg". I can find nothing in the manual that tells me what the difference is. If ALL other buttons can be uniquely configured for each Bank, then I think I might be able to settle for just going that route and reconfigure every button & pad I can for patch change request to the XV and double that amount of patch changes by switching banks. Still doesn't get me anywhere near the options I had with the M-Audio, but I really need to know if changing banks affects all other buttons/faders.
