User reviews

Decent arp, UI needs work

As the name implies you can get some chaotic sequences from almost excellent Chaos Arp 2, but often these are the result of it not being clear which part of the sequence the controls are affecting or where you are in the UI. Controls are ambiguously named and often obscure, the different modes can lock you out of certain sections while they’re still fully visible, sometimes with no clear way to get back to the main screen. I think the best of these types of sequencers offer controlled randomness, CA2 definitely delivers on the latter but (at least for me) often leaves you wondering how you got there.

Good

I like it
Would be great if they added a midi gate probability randomizer to prune away notes based on a percentage… and an internal slow LFO to drive that. Would be so great to have all in one device

Good

So far so good … will give a better review later
