+ Really innovative user interface. It might seem very alien at first, but once you get it, you won't be missing that software editor that you initially thought would be useful...
+ Great sound quality.
+ Lots of modules, and more modules are coming with future updates. Its essentially an infinite modular rack in a small box that you can fiddle around with on your couch.
+ Lots of youtube tutorials for how to use the pedal and to learn about the various modules. Being new to the world of modular synths, I have learned so much from this device.
+ Easy update process. No need to fiddle with drivers or annoying computer programs, -just download the update file put it on an SD card and insert the card into the pedal. (I wish all companies had a similar less computer dependent update process...)
- The button panel became unresponsive on my unit after a few months. However, I contacted Empress and they told me that it is a common problem with the initial batch of units, and they were kind to send me a new button panel for free which wasn't too hard to install myself. I feel confident that this button panel can last longer.
