Hi all.
Just gave a friend some advice on how to sample an organ and then a light bulb went off in my own head.

In Prog Mode if you take a init patch and assign a Sine Wave to it. Then assign 9 copies of the sound to a COMBI. Finally, transpose each track accordingly to match the pitch of drawbars you pretty much have the basics of producing a Organ sound.

And.... your Sliders now act exactly like drawbars allowing you to mix the tones together to product the organ sound as you like it.

With a little programming you can create a Percussion noise and add that to track 10.

Using effects you can simulate your leslie, distortion and an array of other things.

Why would you do this you might ask when the OASYS comes with a CX-3 built in.... well just think about it. You now have all the power of HD-1 filters and its multisamples to create new types of sounds that far exceed all abilities CX-3.

You are now in a position to make some amazing new organ sounds, or even go far out and mix in new waveforms.

What ya think ?

Sharp.

Sharp,

You're brilliant. But I would defer to your superior programming skills to create "some amazing new organ sounds." I would be willing to pay to get more good organ combis.

Sharp I will try this. With M3

I did this on the M3 a LONG time ago. Lemme find the link to the M3/M50 combi I created...

EDIT: KarmaLabs is down for maintenance ATM. As soon as it's back up, I'll post the download link...

Going to try it myself today.
I've been really thinking about the possibility here to go far beyond the normal and the idea sounds really interesting.

Even working with the CX-3 to extract certain elements it uses to make it's sound can be explored through resampling. For example, resample the percussion sound. I've also been messing around with an Audio Editor that allows you to generate Tones. You can get different Sine waves from programs like that have an interesting feel to them.

Although I bet the real fun won't kick in until your shaping everything under HD-1. What would an organ sound like which has access to other multisamples too from the simple waveforms. Or how about a wavesequencing organ.

Sharp.

What you describe is how an organ sound project has been done on Access Virus Synths quite a while ago, and there was a similar project for the Fantom G.

You can in fact fake a drawbar organ this way, but there is one major drawback: the pure sine is not remotely sounding as fat and vivid as a real B3: the sine wavwes sound quite flat and lifeless instead. You can add a Leslie to make them sound a little better, but they will never sound really good.

True, if you leave the sound unprocessed but remember, the idea is to use HD-1 to shape the sound, use all the power of the OASYS effects, and even try different waveforums.

The end results... well feck I've no idea. Could sound crap, could sound really cool. Either way it should be fun just to try.

Sharp,

Here's where we discussed this a while ago:

Here's the link to the M3/M50 .pcg I created back then. It's a good starting point:

It's cool method for building maleable sounds with predictable performance characteristics.

Doesn't have to be sine waves. Could be any wave - simple is better - tri square slope, etc.. The stacked harmonic 16-8-4-2-1.3 or SUB-root-5th-4th-M3-m3-M2-m2-fractional is just additive synth [JUST!!!] - the point tho' of having tonewheel modeling is that imperfections in the wave give the org (or any other additive sound) it's signature character.

Sounds like sound-programming on combi-level instead of program-level. I think it's more interesting for different sounds than an organ. Thx for the inspiration!

PS to sharp -

To act exactly like organ drawbars the CC sliders have to respond upside down - maximum at 'zero' not 10.

Respect.

I think you'll find that the whole idea of a 'combi' and many of our modern 'workstation' concepts regarding mixing multiple sounds stem from the original concept of the pipe organ (leading into electric organ and string synthesizers). It was all about mixing different (quite often 'imitative') sounds together onto certain notes.

The electric organ with distinct harmonic control (like the Hammond and copies of it) is actually an unusual implementation of this, but it was a technical restriction which lead to the harmonic blending rather than using different waveforms. Organs with distinch waveforms at more basic 'musical' intervals like octaves and fifths, like many 'combo' transistor organs, are more true-to-form.

I actually studied the origins of the pipe organ and had a section on how the concept has evolved and lead directly to modern electronic keyboards, as my 2nd year dissertation at university.

This also lead on to parts of my final year project which produced a nine part sampling synthesizer. You could have any multisample for each 'component' (basically a timbre or drawbar kind of thing), with various FX routing, vector control,, and you could also program a 'rhythmic triggering' pattern across the 9 components, a bit like wavesequencing.

Off topic, but related.

A scheme much like what we're talking about here was described in the novel "cryptonomicon" by Neal Stephenson - about codes, cryptography, math, and buried treasure, among many other wide ranging topics. One particular plot line hinged around using pipe organ additive harmonics to describe 1's & 0's in the worlds first, and no doubt noisiest, binary computer.

Worth a read if you have time.

This reads fantastic Sharp. And since the CX3 uses many oscillaotors activated even when not playing, this acts as a more cost effective methodology in a recording environment where you're only using a few oscillators.


Could this thinking be applied to create a string machine type scenario too?


And - since MOD-7 offers 6 oscillators - could this be done in minature in a MOD-7 program (or across 2 MOD-7 instances in a single program).


You've definitely tapped into new possibilities on the OASYS. There are other similarities floating around my head not a million miles from this - I responded to a Kronos post recently abd and realised that through a combination of polyphonic unison, 2 EX's per program and combi mode you could layer up to 192 oscollators on a single note in a MOD-7 program and about 300 MOD-7 oscillators if combined in a combi). Think of the 'Tomita'-type Choral and soaring string programs possible if carefully programmed.

The openended nature and complexity of OASYS program and combi architecutres is no doubt untapped in a myriad of similar approaches.

Nice one.

Kevin.
