Maybe the best way to approach this is to ask: what features are you specifically interested in? I don't know all that much about the Liquid Foot controllers, but I can tell you for certain that I've put lots of effort into giving the GT some serious breadth of features and expandability. If we don't have a feature that another controller has, it probably wouldn't be all that hard to add. I'm already adding several features that our beta testers have suggested that I had never thought of. Let me know! I'm open to suggestions. My intention is to keep expanding the GT's capabilities through firmware upgrades for years to come.
I'll admit we've missed our projected release date many times, but this time it's for real. Parts are on order and are arriving shortly. The wait will be worth it in the long run - every time there was a delay it was because I found a better way to do something, and the controller is way better than the prototype we showed so long ago.
