Tritone Paradox

Hello,

I need to build a patch to show the tritone paradox (two tritone-related shepard tones played in a row).

I found a couple of patches here, working with shepard tones but most of them were quite complicated and had several other functions ...

Can anybody help me building such a simple patch or give me a hint where I can find one?

Regards
Jln

I didn't know about this particular auditory illusion, so thanks for posting about it.

I recreated the stimulus pattern from Deutsch 1984 as best I could, although I have only approximated the amplitude curve that they use because I don't know how to make that equation happen in Max.
