I'm interested in adding a live generative music element to a rock opera I'm working on. I'm having trouble understanding what sequencer and/or quantizer would be best for this.
This is all very theoretical right now, I am just starting to write this thing. But for my ideal wants, the system would be able to:

• Generatively select pitches from a scale or key
• Change which scale/chord it's selecting notes from on a fairly arbitrary rhythm (odd time signatures)
• Edit the pattern of chords and rhythms in real time, without distracting the player from their main expression of creativity, which is through changing the sound of the instrument

And it would be kind of nice if I could speed up or slow down to match the speed of live musicians.

Anything come to mind? I looked at a few sequencers but I'm kind of drawing a blank. I don't think I'm experienced enough with sequencers to tell if they're able to change stuff around in real time or not.

Setting the topologist's sin curve to have a fixed frequency doesn't look like it works, since the curve is a sin with a constantly decreasing frequency. Also, its frequency at the origin approaches infinity, so you might have to find some workaround for that.

I don't really understand the topology aspect of it but I bet you could get a decent audio version out of Desmos.

Wow I meant to say switch, not knob.
That's quite the range, seems pretty perfect.

Thank you both for the replies. The Orbit in low mode goes a little further into the audio range than the diode chaos but it's like using a nuclear bomb to shovel your garden for my purposes. And it still doesn't go as far into the audio range as I would like. I find that's the case with a lot of oscillators and stuff with lfo/audio rate switches too.
The Hypster seems just about perfect, relatively speaking. Neither of the colorfully named knobs are secretly a range knob, are they? I haven't been able to find a demo that shows how low/high it can go and the documentation is a little sparse.

Are there any chaos modules that have the ability to go from LFO rates to audio rates "smoothly"? Ideally with some kind of semi-controlled rate knob like in the zlob Diode Chaos. Diode Chaos almost gets there but it barely touches audio rate and doesn't seem to have a ton of room on the knob for exploring up there.
I could do this with a lfo/oscillator like the Pittsburgh oscillator and a clock-based chaos module like the NLC Squid Axom but then the rhythm would not be chaotic, only the voltage.

+1.
I just got a 1amp power supply to replace a broken one, but I am almost at 1 amp just with a couple digital modules and preamps with phantom power. I have to be very careful about power consumption in my planning for now, and it is pretty hard to figure out what I can or can't do just with the tools on the site.
