This is a great input module for its wide range of uses. I'd prefer it be in a 4hp package, but it offers a lot of versatility in the 8hp. The envelope follower, eurorack or audio input, and the adjustable gate are very versatile. I have 2 of these units. My only request would be that it be shrunk, so I have more room for other performance modules. There's nothing that compares to this in the price & functionality department, if you'd like to use the envelope follower & gate.
