Sine Sine Everywhere a Sine

Blueberry Thing version 0.0.7.4 (SVN 79) is up, and is primarily a bug fix for the Geo Blend waveform type problem with OSC 2,3,4 as mentioned above.

ok, but no need to try for intel peoples? am i right?

Ctrl+O opens it.
It lacks of the CTRL+Q, but the red button on the high-left corner work as the quit.
I've not tried to manage samples with it yet.

The missing File->Quit menu item, with Ctrl-Q assigned to it, seems to be a wxWidgets bug on OSX (Linux, MS Windows, and Wine all show it). And there are other cosmetic issues on OSX as well, for example the starting screen position of the window is "under" the top desktop bar, etc. All of which I hope to fix someday.

I realize that the Quit menu item is supposed to be in the BlueberryThing menu on a Mac, but if it were (temporarily) in the File menu and it got Ctrl-Q working, would the Apple gods be wroth?

It works on Intel Macs! (They come with a PowerPC emulator called "Rosetta" which automatically executes PPC bundles)

Now I just need a tutorial video to see what I can do (and how) with it...

Aha! Right - I'm going to try this

EDIT: 2 knobs unresponsive, no "Help" text. Ah well....

Cool, where is the download link for the new build?

thanks..

Knobs - they work on the good ol' G4, but suffer from the same issue as the Windows build, in that if you drag beyond the boundaries of the knob you loose tracking. I spoke to the wxWidget gods about this, but nothing has been decided. Eventually I will rework this if I have to.

Documentation - The Help menu is there to make people mad. I assume it's working then.

Blueberry Thing Crash Course

The GUI is divided into 4 sections: Audio Sources (top), OscWaves (middle), OscWave Options (lower left), and Zebra Waveform/Italy (lower right).

Audio Sources:

Load an Audio Source with the menu File->Open Audio Source. It can be any sort of wave file (except Ogg or Flac, which will come with the newer sndfile library soon-ish).

Some useful Audio Source mousings:

Left Click/Drag - set start point of the wave
Right Click/Drag - set the end point of the wave
Middle Click-n-Drag - drag the display horizontally
Alt-Left Click - set both start and end points of the wave
Mouse Wheel - Zoom In/Out
Ctrl-Mouse Wheel - scroll display horizontally

The OscWave buttons:

Yellow - selects that OscWave for editing.
Green - Enables that OscWave for output in a Zebra Script (you need at least one on).
Orange - Turns on/off the highlighting in the Audio Source of an OscWave's audio.
Waveform - chooses whether the analysis is for GeoBlend or SpectroBlend
OscX - The Zebra Script can send the Waves to all (and only) *active* OSC's in Zebra

Options:

Audio Source - chooses one of the Audio Sources (Blank is boring, so change it)
Channel - chooses which channel(s) of the Audio Source is used

GeoBlend options:
Interpolation - bit uncrushing

SpectroBlend Options:
Window Function - chooses whether the audio clip is attenuated with various curves
Zero Pad - pads the FFT sample window with additional 0's to improve the analysis
Base Freq - the frequency of the first harmonic in a Spectro Blend wave.
Gain - MAKES IT LOUDER (large FFT sample sets need more of this, so crank it up)

Zebra Waveform/Italy:

Urs has still not posted any pictures of the Mediterranean, so all we have is my terrible rendition.

Other:

Edit menu Copy/Paste works to copy OscWave options from one OscWave to another.

Broken Stuff and Wishes:

No ability to save your Blueberry Thing project
Alt-Left Click is not supposed to recalculate the FFT until both points are set, but it does.
The Audio Source highlighting on the OSX 10.4 isn't working (just gray).
Once an Audio Source is loaded, there's no way to get rid of it.
OSX moves the Quit/Ctrl-Q menu item to a galaxy far far away.
The Help menu isn't very helpful.
The Zebra Script button artwork takes you closer to a Zebra's rear end than necessary.

Okay, if I want to try that clever trick where you take a vocal sample and spread it across four Osc's, how do I go about it? Do I have to manually chop the sample up and feed each piece to it's respective window?

You only load the sample once as an Audio Source, and then select each OscWave and set start/end points for each OscWave, so the manual work is in Blueberry Thing. I would recommend using a Hann window function, and overlap each piece somewhat.

Howard perfected the multi-OSC Wave sweep, by making the last Wave of each OSC silent, and the first Wave of OSC 2,3,4 silent also. So in Blueberry Thing you want to disable those particular Waves (or at least point them to the Blank audio).

Inside Zebra, you might want to just download Howard's example and study the MSEG's. Basically they sweep the Wave parameter of each OSC at the appropriate time, and sit on a silent Wave while waiting, and/or after having finished.

Right, I get it. I was thinking that the whole process from slicing to conversion would be automatic - feed in a sample at one end and the Zebra Osc/waveform(s) comes out the other

So, I guess this is kind of a souped-up version of Wav2Zebra, with some extra options, but the main difference is that any sample slicing is done within Blueberry rather than beforehand in an external audio editor?

The GeoBlend mode in Blueberry Thing is very much the same as Wav2Zebra, although it is important to remember that Blueberry Thing is not an "editor", it is a "generator". I don't recall if Wav2Zebra allowed for editing, but if so, that would make it uniquely different from Blueberry Thing.

I doubt that using Blueberry Thing in GeoBlend mode will produce quite the same effect as the patches that I and Howard were experimenting with using the Octave scripts and FFT analysis, since the waveforms that Zebra generates internally using SpectroBlend are probably much more complex harmonically than can be represented by 128 points in GeoBlend. No doubt Urs can comment more authoritatively on this.

Now that I denied the existence of any such automatic slicer dicer whachamawhozit, it makes sense to add this to my dreamy list of dream features, but not available before April 2010.

ok, i load up a sample in blueberry thing..selected one green knob of the single sprectro blend osc i would like to choose, i used the hann mode...then i've chosen a random preset created by myself with actualy a geoblend osc in it..does this preset has to be an spectroblend osc included?


anyway...im not able to load this preset anymore..it just skips in zebra...

what am i doin wrong?

thank & heads up for the great work man!!

cheers
