    1. Yeah this is the guy that does a lot of the Modular Monthly stuff on the Future Music channel. Great stuff. You should check that stuff out if you haven’t already

  1. The Stepper Acid has been available for quite a while, and it really is a nice bit of kit.
    This video is quite fun and enthusiastic. I really like the emphasis on showing how the detach mode can be used , which in a modular set up really differentiates it .
    I bought one of the early Stepper acid modules, and it made me think I should be using the detached mode a lot more. Well done Transistor Labs and Mylar melodies
