Is it possible to produce Risset tones in Zebra?
Thankyou in advance for any help/advice.

I don't have Zebra but will post this possibly helpful link for those who don't yet know what "Risset tones" are:
http://en.wikipedia.org/wiki/Shepard_tone
Maybe that will ring a bell among Zebra sound designers.

Well according to Meffy's Wiki link a Shepard/Risset tone was used as a sound effect in the film The Dark Knight (note 7 right at the bottom of the page). There's someone who posts on here might know something about that.

Though I may be wrong, I don't really see how that would be possible, as I think you would need to specifically program this (in the code sense, not the patch sense) as a synthesizer module. Shepard tones would be easy of course, as you can do them in any sequencer. There is a free Risset plugin that can act as a ring mod, as part of the endless series, if that helps (also a non-free, but inexpensive flanger, phaser, and pitch-shifter). You could either use this following zebra2, or as the input for zebrify if you have the beta installed (or maybe zebra2 -> endless tone -> zebrify).dionysus wrote:Is it possible to produce Risset tones in Zebra?

It's possible, and not too difficult with two oscillators and one MSEG.tylenol wrote:Though I may be wrong, I don't really see how that would be possible, as I think you would need to specifically program this (in the code sense, not the patch sense) as a synthesizer module.

Here's how I did it, I'd post the patch but I've been messing it up all over with effects and too lazy to post the cleanest version right now:
Make a very long note in a sequencer, or latch a note or something.
Start with the case where OSC 1 is an octave below OSC 2, with OSC 1 in channel 1 and OSC 2 in channel 2, but similar in every other way.
Then move to the case where OSC 1 feeds and OSC 2 sidechains into the MIX device in chain 3 (and mute 1 and 2 such that only the channel mixer passes audio to the eventual output). Set the MIX's mix knob all the way to the right so OSC 1 is at zero volume, and OSC 2 is at full volume.
In the ModMatrix, modulate the MIX's mix knob by MSEG1, value: -100 (all the way to the left). Then set the MSEG to be a saw-up type of envelope (should only take two points, straight line) over a fairly long period of time of several seconds (of course 'seconds' is a good time unit here).
At this point, OSC 2 should fade into OSC 1 over the course of one cycle of oscillator, with a hard reset.
There's only one step left - use MSEG1 to modulate the tuning of OSC 1 and OSC 2 by 12 semitones.
There are plenty of variations one could do at this point like making a risset tone chord, or using a funkier MSEG, or modulating OSC sync in parallel, metalverb algo on the reverb is cool.
