Very peculiar

A nice take on the arpeggiator concept. Try this at very low BPM.

Better than your current arp

So get it!

No midi out

It doesn't work, lights flah but no midi signal to an hardware synth. Meanwhile others two apps works fine. No setting, just channel.
Any solution?

Response from developer

Hi, you can find ChaosArp in AUM by first adding a MIDI track to your project and then opening the 'Audio Unit MIDI Processor' menu. ChaosArp should be visible on the list. If not, please contact us. WIth Best Wishes, Achillefs Axart Software

Super dope midi tricks

I love the idea of generative midi. This is quite nice, even on outboard gear! I think I ran this and Binarhythmic midi out to cat and edge. Amazing results, and not just random sounding. Sounds more intentional and focused once ya get the hang of it. cheers!
