Is there a RS2014 stomp-box that can replicate the effects created by a step sequencer? It sounds like this. I've played around with the envelope boxes, but I can't quite get it.

 

Thanks in advance :)

Not really, the closest thing to that would be to have 3 to 4 setup with different wah value that you change to simulate what the step sequencer do but it would be a heavy thing to do and that will also used most to all of the tone you can use on one part.
