How to make a shepard/risset tone with the sine bank module?

Michael O'Hagan

I am trying to create a shepard/risset tone generator using the sine bank module, I have tried several different methods and none of them have provided useful results.

I want to have a saw/square wave consisting of 16 harmonic partials rising or falling over time.

Ideally there would be 8 layers to make this sound smooth and clean, so 256 harmonic partials in total.

I need to have 8 groups of 16 rising in ratio and fading in and out of volume over time.

Getting the 16 partials to rise in ratio and fade in volume as groups is proving to be a bit tricky.

Does anyone have any ideas about how to do this?

Thanks

Are you trying to generate something that sounds like a clean Saw or Square wave that just keeps rising in pitch? or is it ok to have the unison style phasing and beating effects that naturally occur when multiple complex waves modulate at different frequencies?

Pulsing and beating would be fine.

I'd preferably like to be able to do both and have a button to switch modes, but getting something working as a starting point is where I am at now, so I'll kinda take what I can get to get things going.
