Hey guys,
I notice when I load the B3 presets off the EMU discs that most of them aside from the note itself have this underlying overtomes for lack of better word while in some instances it is a nice sound . I would like to creat preset without all those other notes in the background.
Can it be done using these presets ?
I know it may ruining the characteristic B3 sound but think they have their place elseware sometimes.
thanks

Subtones is actually not created within the E-mu itself. Because of the leslie-effect on most b3's and all the added sinus-waves which creates the hammond-sound it is a law of physics that creates those subtones. When you play a sinewave at for example 480 hz and one at 440 hz at the same time those waves will create a subwave at 40 hz, the difference between those two frequencies. Subwaves will not be strong, but might be audible both in itself and as the effect it does on the combined soundwave. In my example you would hear it as a sort of "un-tuned" effect on the wave, almost as an extremly fast vibrato, in Norwegian we call it "svingning" but I lack a good English term for it. Maybe somone else can help me?

Hey Ole,
Sounds like since it is within the sample itself it cannot be removed ?
One would think that a certain combination drawbar setting on a B3 would create a tone without these ? I don't have access right now to one but sometimes they pop up at work. will give it a try .
In meantime who else makes or has good B3 samples or presets out there?
and on a side thought Mellotron as well ?

Thanks

It might be inside the samples itself if you can hear it when you only press one key, then you might be able to remove it using a high-pass filter. But, you will most likely get it when you press down two keys. Some drawbar settings will not create it, because some harmonics do not create subtones, because they is part of the natural harmonics of the main pitch. So, if you combine the main pitch with for example a fourth or a fifth above you will not get subtones. If you try with a third you will get one. If you are using any other waves than pure sine, or effects like for example a leslie-simulator you might get them anyhow.

This has to do with what waves can exist on the same main frequency without disturbing it. I find it quite hard to explain, especially in English, so you might be better of checking out wikipedia than trying to understand me.

Understand, seems like law of pyshics (in the audio realm) kinda thing.
If you have the old EMU disc # 7 Classics, It is on there.
happens on one key pressed though. It almost sounds like several tones together under the note thereby making a chord but way in the background. these "chords" throw off the chord voicing I want to use.
Will keep digging.

thanks for the quik reply.

Actually got that disc, but my e-mu is away from reach if it's only one note that is destroying your chord I suggest you use a high-pass filter one just that key. One way to do it is to remove that key from the original preset, create a new preset, add the sample, high-pass it, and make it sound on just that key and link it togheter with the old preset. I'm sure there is an easier way, but I can't think of right now.

I have a .wav file to upload somehow , so you all could hear what I am hearing in these EMU disc factory presets.
Is there a way to upload it?

Thanks Ole for cking in on my old post .
here's the link to B3 soundbyte:

and I just double cked to make sure it's there -it is -watch out for the pop ups on that site though.

It's normal with those overtones, it is in many ways what defines a b3. So, it's not something wrong the samples. If you need a cleaner organ, check some of the other presets, or try using a lowpass-filter. It might help.

Thanks
ole, I suspected it may be the sampled B3. I hear alot of B3 on tracks that are very "clean" so it may be just the drawbar settings kybdists are using.
I'll try the Low pass filter though it maybe hard to target those freqs.
Any other good B3 sample discs out there ? trying to build a wide catalog of them.
Cheers

Syntec's "Wall of Sound" CD (Vol.3) has a few good Hammond presets.

I think the English term for this is beats (or beating). Yes, I know, it's as confusing as most of the rest of the English language.

I usually notice it when tuning a guitar. But I think svinging is a much better word!
