Adjustable octave warble tone generator

Does anyone of a (free) software tone generator that will let me select not just the frequency of the warble tone but also how many octaves. Typically its 1/3 octave, but I'd like to use smaller octaves like 1/6th, 1/24th...

good ol' SW has a signal generator that can do warble tones and will let you adjust the range!

Burn a CD with warble tones, generated with Cooledit or something? Or there's some test CDs that have warble tones or band-limited pink noise. Denon Audio Technical CD, for one. If it's out of print, evil people may have shared it as a torrent or something. There's some freeware audio test CDs too.

If you burn them as MP3s, an MP3 player would display the name (so you wouldn't need to count tracks on a CD player). A small (32M) (obsolete) flash player should be more than enough space.

How does one bring up that dialog? I looked at the help page for it. It does not say how to navigate to it.

Thankee.

Edit: I figured out how to make the dialog come up. Now how do I play the tone? The "Apply" button is grayed out, BTW.

Trying to get Speaker Workshop to generate a warble tone. Here's what I've done:

1. I go, "Resource/New/Signal" and create a new signal. It shows up in the project, but it contains a default signal, a sine wave.

2. I click on the signal resource in the project window, and click on the "Edit properties" button.

3. The advertised dialog comes up, but when I click on the "Warble" tab, the "Apply" button is grayed out, so I cannot change the signal to a warble tone.

4. I scratch and cuss.
 
I built a step-tone generator several years ago. It uses the XR2206 whose frequency control pin is select different resistances (pots) via a cmos multiplexer driven by a counter and a 1 Hz clock. Each of 8 tones is on for 1 sec and then repeats.
