I use this for not it's intended purpose, but as a random midi-gate. With proper settings, you can get only 20% notes through, or whatever you might need. It's not really meant for that so there's few caveats, as in you need to define the note length which also happens to define the frequency of the "gate". So it's not going to rally match your incoming notes perfectly.
But it's extremely lightweight, does something that I haven't found anything else to do. Except Hypercyclic which is unstable & available only as 32-bit -- also is way more random. Actually to be honest, I am not sure it even can do the same thing... but I am erring on the side of caution. I seem to recall it tends to prefer adding random notes instead of working like a gate.
But RandArp also works as a random arp, as intended. But I never use it as such.
Thank you so so much for such an amazing effect. I was like oh another arp whatever but I use Chordz and its amazing so why not give it a try and Holy #&%*@ this little plugin just boosted my inspiration and fun by a million! Thank you for making such good plugins and giving them away for free. I will donate as soon as I can.
