How to make wavetables for rapture

A friend of mine has about 16 vintage synths (jupiter 8, moog so on) and i would realy love to take samples of the raw waveforms to make wavetables to be detuned and multi voiced for rapture, can any one shed any light as to how its done, obviously some sort of software application is needed

Good man, cheers

you have muz3um I'm guessing also (free download)

I asked / got permission to use eXode's stuff  , I should get on with it..but well life got in the way. sure you know his refill work

b-rock, was there a tutorial ever put out for the fi-sounds pack? I bought it ages ago, you just reminded me with your icon.

shorten some of the multisamples that came with that and osc them up

Here's an easy method for creating oscillators from wavfiles much longer than 3000 samples.  Keep in mind that long sample conversion will add to the processing overhead, so trim the files down to the bare minimum.
 
--------------------------------
Open up a text editor (Notepad), and drop in the following line:
 
<region> sample=SAMPLE FILE NAME.wav oscillator=on
 
Substitute the proper file name for SAMPLE FILE NAME, and save it with an .sfz file extension.  Place both the SAMPLE FILE NAME.sfz and SAMPLE FILE NAME.wav files next to each other in Rapture's Multisamples folder.
--------------------------------
 
Now you have a single wavfile pulling double-duty.  The .wav alone will play back at recorded pitch on middle C / MIDI Note 60, as a "one-shot". It will be transposed, shortened or lengthened at other MIDI note locations.  The companion .sfz file will 'compress' the .wav characteristics into an oscillator.  This wavetable won't sound much like the original wavfile, but it will yield some very interesting results.
 
I happen to like the results derived from complex targets, such as an open hi-hat sample.  But any source is fair game.  It can be a loop, pure noise, vocals, etc.  The first page of that "Purebred Wavetables" document (linked above) pictures a series of 10 sine .wavs played in descending succession over 10 octaves.  When converted into an oscillator, it sounds like a cascading sweep of overtones / harmonics.

how do create the sfz file extension

Cheers man, appreciated

Done it now mate, typed the file name instead of what you said, thanks alot b rock, your a good man :)

Three quick questions:
 
1).  Can you load the original 'raw' sample (.wav) into Rapture (Load Multisample dialog)?
2).  Have you checked the .sfz file for extra spaces, naming errors, etc.?
(You can copy your .sfz file text and paste it into a reply here.)
3).  Are you getting any error popups (sfzlog)?
(You can copy the error log contents and paste them into a reply here.)
 
EDIT:
I see that you've had some measure of success.  The end results will vary widely; depending on the original sample source, the length of the file, etc.  If this first experiment sounds like it has a HP / BP filter on it, look to the frequency distribution of the sample source.
 
Rapture is going to interpolate everything in the source sample, and 'reduce' it down to fit an oscillator's characteristics.  A .wav file of several seconds will get 'squeezed' into the space of a few thousand individual samples.
 
I don't know what you've used as a source file, but you can try some simpler .wav files, and build up to more complex ones.  Perhaps some single notes from a synth, or some drum hits.  You have to try a few dozens examples before you can get a 'feel' of what to expect in the results of a "forced oscillator".

Lucky.

Are you sure you should be allowed out with a loaded synth?

****ing right i should, program most of my patches any way mate (lol)

You might poke around Patch areana.com.

B rock still shows up sometimes.  That was his work, I believe.

Thanks, the name of the article is fairly enticing and indicative of obvious valuable information worthy of being kept up with. I am just now getting into those synths and anything and everything I can learn about them is of great interest to me, so thanks again and again.

  The Steal this Waveshape! tricks were among my favorite Dim/Rap/z3ta+ techniques.
 
 

Aw man!  I'll second that! 


Maybe we can ask Bob (techead) if he might have a backup or a way to get in touch with Mike West to see if we can extract text and images from any backups he might have?

I'll check my externals here, but I probably only would have saved images or pdfs, not the text from the wiki pages... doh. 

Are those the articles? They don't include the images, but maybe they might be useful.

 
That's them.  Thanks.  I also happened to find the related images on an old backup drive, too.  (I should've been searching for "stolenwaveshape" instead of "stealthiswaveshape".)  All the parts are in place to reconstruct both parts of the article.  Except ... that it really should be updated for z3ta+ 2.
