The EQ Page

When you press the EQ soft button, you'll see a page that at first glance looks quite similar to the
ALG page for a VAST program. The four blocks on this page, however, represent two shelving
bands of equalization and two parametric bands. The KB3 EQ offered here, though, is not
implemented as a true EQ section, instead it adjusts the volume of the tone wheels based on
frequency. If the tone wheels are based on sine waves, then this acts a lot like a real EQ.
Parameter Group (Available for each EQ Block)
Gain
Frequency
Width
Each EQ section has Gain (G), Frequency (F), and Width (W) controls. Frequency controls the
center frequency of the band. Width controls the bandwidth. Gain controls the amount of boost
or cut.

All the Other Pages

The rest of the pages—LFO, ASR, FUN, etc.— are the same for KB3 programs as they are for
VAST programs, so we won't describe them again here. Begin on page 6-40 to find descriptions
of these pages.

Programming Tips

This section provides some starting points for creating your own KB3 programs. Remember that
you'll have to start with one of the existing KB3 programs.
As described below, the most prominent difference between organ vintages is the number of
tone wheels used. Keep in mind, however, that the sound of an actual tone wheel organ will
depend not only on its age, but also on how well it has been maintained.
Octave folding, where an octave (or part of an octave) is repeated at the top or bottom of the
keyboard, is handled automatically by KB3 Mode, emulating the folding done on actual tone
wheel organs.
Early Tone Wheel Organs. Instruments of this period had 91 tone wheels. To get this sound, go
to the TONEWL page, select 91 tone wheels, and set lowest pitch to C 1. Start with the Junky
Wheel Volume Map and Bob's Organ Map. You may also want to increase the Key Click level,
since this tends to become louder on older organs.
