About
the acoustic of an Hammond Organ
As you may read in the presentation of the Hammond XB-2, it was already very difficult for the
Hammond Suzuki engenieers to obtain a good digital translation to
the famous Hammond B-3 groovy sound
After having discovered the power of the Roland Sound Canvas
SC-55 thanks to the SCPOP and the moral support of , I tried to make the same job to obtain a Hammond
sound.
Basically , a Hammond sound is an electronic sound , and it would
have been achieved without many problems. The famous drawbars are
representing the registrations as shown on the image. Those
indications have been coming from the well known dimensions of
the pipe in the original church organ. I play one
single note
like a C4 and pull all the drowbars
| C2 |
G3 |
C3 |
C4 |

C5 |

| 16" |
5"1/3 |
8" |
4" |
2"2/3 |
2" |
1"3/5 |
1"1/3 |
1" |
Every drawbar does have16 different volume position , between 0
and 8 . The drawbars give the possibility to create an incredible
range of sounds (253.000.000 ) , wich are most commonly raked
into 4 main Family:
The
Flute family
| Flute is only using square notes , like
8" and 4" . It gives a peaceful . |
Flute sample(in this sample I used
first 8" and 4" then 2" 1" and 16")
The
String family
| A full sound with the most middle tones |
String sample
The
Diapason family
| A sound based upon the lower sound. |
Diapason Sample
The
Reed family
| A bit like the String sounds , but more
middle and less extreme sounds |

But !!!
The sound of a
Hammond like my XB-2 is not only characterised
by a oscillation like the one obtained in the Sound Canvas
Library by an Ocarina but also by some noises and clicks
so that I had to use some less used sounds of the Sound Canvas
like the F1 Key CLick and the Bottle
Blow (wich
already was used by Raffaelle and Filippo)
Percussion
The organ has also
a pescussive sound wich is similate to a very high marimba . With a played C3 , the
Hammond may add a very short Marimba at C5 or G5. Together with a
Ocarina , a F1 and a Bottle Blow , it gives a strange
sound ,
wich after filtering thru CanvasMan gives a jazzy sound like in
the very known tune of Jimmy Smith called The
Cat . I
recorded this tune in 1993 but it was then only possible to play
it with the Hammond XB-2 wich is a Midi Hammond . The original
sound of the Sound Canvas was too poor to give a satisfying
result. Now , with the SysEx , it gives some better results for
jazzy purposes.
How to build a
Hammond Sound?
The major problem
of the SC-55 is te voice limitation to 28 (happy users of SC-88
does not have such a limitation indeed!). If you listen to this Impossible
Sample you'll
clearly ear the mess when the 9 drawbars are open and you play
together more than 3 sounds. You get frequent note off limitation
and the result is not very nice. Due to voice limitations, I had
to look for some different sounds as shown in the sound family
table below.
The results are
not 100 % satisfying
Honestly , I
didn't really reach the perfection as Raffaelle and Filippo for
the Pipe organ , or with the Harpsichord sounds. I just now have
some interesting sounds wich are giving a slight impression of
Hammond , specially when mixed with other instruments like Rythm
or Brass section.
You'll find in the different SysEx into the Hammond Template file
for Cakewalk some of the drawbars indications , but feel free to
give other names like jazzy , psychedelic , fuzzy ...
The Hammond
template file
After having
created the sounds , I gave them to Raffaelle who made a template
file to use in Cakewalk, wich contain sysex producing the
following sounds:

The move to EZCAD3 represents a significant step up in capability, especially for users who need 3D engraving, advanced material handling, or multi‑axis motion control. However, it also means investing in a new controller and a new license key. For basic 2D marking on older machines, EZCAD2 remains a viable and stable option.
