K2vx Compatibility Files
Included as part of your K2vx accessory disks are two disks of compatibility Þles, for your use
when playing K2000 programs on the K2vx. The Kurzweil K2000 has been a widely used
platform for several years, and the VAST architecture and programming interface is largely the
same in the K2vx. Therefore, an attempt was made to organize the K2vx factory objects in a
way most compatible with existing K2000 Þles. However, several improvements have been
made to the Base ROM objects, and therefore not all K2vx support software will play correctly
in a K2000 without some minimal translation.
The purpose of the Þles on the two compatibility disks is to allow you to play programs,
sequences, and other objects that were created on a K2vx, so that they can be re-saved in a
"native" K2000 format.
If you never owned a K2000 and you do not have existing material programmed on the K2vx,
you probably do not need these Þles.
Here are the main differences:
ROM Drum samples. While most of the samples in the base ROM are compatible between the
K2000 and the K2vx, the drum samples are not. The K2vx drums are made from new
recordings, and a slightly different selection of drums is offered (e.g., three ambient snares
instead of four). Furthermore, where all drums and percussion had been grouped in one multi-
root sample (Sample #20 Drums and Percussion), they are now available as separate samples
addressed by number.
ROM Effects programs. These were re-programmed for greater signal-to-noise ratio, and re-
organized for ease of use. The Effect page in the program editor always points to an Effect
program, and has several parameters for real-time control. Many programs developed for the
K2000 series utilized those factory default effects. When these programs are loaded into a
K2vx, they will not call the correct effect.
ROM Keymaps. An effort was made to keep instrument keymaps in the same order as in the
K2vx, because the keymap must be correct for a program to sound correct. Keymaps 20-38, 61,
70, and 173-176 have been replaced or deleted, and subtle improvements in volume have been
made to others.
About the compatibility Þles:
There is one main Þle on this two disk set, K2KBASE.K25. It contains all the necessary objects
for a K2vx to play any program made on a late model K2000, including drum and percussion
samples. If you do not have sample memory, you can still use this Þle for some compatibility,
but the drums will not play.
The idea is to temporarily overwrite the ROM in the K2vx with these objects, so that K2000
programs can be loaded, played, and then re-saved with their dependent objects.
If you use the compatibility Þles often, you will Þnd that sometimes you only need to load
some of the objects from the big Þle. This can be done with the Load Object feature. As a
convenience, we have provided a Þle which only contains effects programs, K2KFX.K25, for
one such case.
We also included a Þle for Orchestral ROM compatibility, K2KROM1.K25. It should be loaded
in tandem with the K2KBASE.K25 Þle only if you have the Orchestral ROM option installed.
(There are very few differences between the K2000 and the K2vx in the Orchestral ROM bank,
so this Þle will rarely be used.)
