Subject:Re: Anybody try the B3 emulation on a Kurzweil PC3 series?

The normal Kurzweil KDFX Leslie is built inside one "block" of the KDFX system, and uses 7 units of an available 16 (on the PC3 or PC3K) of effects. Each of these Leslie setups is stereo (or mono if only the Left out of the Kurz is used), and there are about 80 or so of them in the factory setups. They are typically named after particular music selections or artists, some emulate a 122, some a 145, some other Leslies. Each of them has been programmed with different parameters like rotor speed, horn speed, ramp up and ramp down time, amound of tube distortion (which is increased with the mod wheel) and so forth. The "Big Leslie" is just one additional one, for those who want a really emphatic Leslie sound. Instead of one block, two blocks are used, which means that 14 of the 16 effects units available are in use. This one is not made to be used in a zoned setup with some other sound like bass or e.p.

Note that the PC3LE does not have as many effects blocks available, so I don't think this particular one will port to that model. For the SP4, only the lighter Leslie setups can port, because of limitations on the amount of effects power (there are a different number of the proprietary Kurzweil effects chips in the different models).

The two blocks show as being in series in the display, but ALL Kurzweil blocks show up as being in series in the display. I don't know if they are paralled or seriesed - I just know that the sound produced is like a Leslie on overdrive. I can say that it makes a very fine sound for continuing my bridge solo when a lead guitarist attempts to wank over the organ solo - and I suspect that is its primary use - that patch CUTS. There are a lot of other patches that are more useful in situations where volume wars are not a problem.

Kind of like: you know how the screaming top end of a Nord Electro 3 cuts through - especially when one sets the distortion high and has a pair of K10's. The gitard better have a real BIG Marshall stack if he wants to shred over it. Just like the Nord in that situation, it is not the sound I'd use for a jazz trio or some other group where the musicians have enough sense not to walk all over each other - but in a hard rock group, you WILL be able to be heard.
