If you are in OS X, hypercyclic is unfortunately abandonware at this point. I have put feelers out there to see if mucoder would revisit it. As fortune would have it, he's very busy, and I hope that's a good thing for him. Perhaps we could ask him to hand the project over?
This is simply the best, most unique arpeggiator in existence. Numerology for example is profoundly more complex and still won't offer you similar results. You could experiment with patching 2 separate LFO devices and see if you end up with something similar, however you would still be hard pressed to find a way to sculpt a harmonic rhythm as readily and surprising as you would with hypercyclic. I have found nothing on the market to replace it. Quite simply it is a lost art.
Love the fact that this is free! There is a shortage of innovative arps out there, and this one is very interesting. I like the concept of an arp which can be controlled by an LFO. Most arpeggiators don't have LFOs.
