Hi @tsicon_9
About step recording, why do you need it in the arpeggiator? If you already know which notes you want to input, you can introduce them in the arpeggiator directly. Unless I’m misunderstanding what you mean by step recording.
Also, there was this draft feature that didn’t go through but it isn’t related to the Arpeggiator: Step input.
About randomize function, you can use the Random modulator and apply it to the steps in the way you prefer. Doesn’t this cover your request?
