This Java applet draws the resultant wave that occurs from a 9
drawbar system Hammond. Each drawbar represents a relative harmonic frequency *(pitch)*.

Drawbar Frequency | 16^{'} |
5 ^{1/3'} |
8^{'} |
4^{'} |
2 ^{2/3'} |
2^{'} |
1 ^{3/5'} |
1 ^{1/3'} |
1^{'} |

Relative Harmonic Frequency | 1x | 3x | 2x | 4x | 6x | 8x | 10x | 12x | 16x |

The numbers 0 - 8 represent the amplitude *(volume)* for a selected drawbar.
The number 0 means off, *no volume*. The number 8 represents maximum volume. Each
number is a gain of 3 decibels.

Drawbar Amplitude | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |

Volume Gain | 0 db | +3 db | +6 db | +9 db | +12 db | +15 db | +18 db | +21 db | +24 db |

In the upper right corner of the applet, is a preset selector. It contains common drawbar settings. If a change occurs to any drawbar at the bottom of the applet, then the preset selector is automatically reset to 00 0000 000. -- Tim Wick
