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
