I was looking for a MIDI controller to use my setup to its full potential. At the moment, I'm using it to control Strymon Iridium, Flint, Deco, and TC Electronic Plethora X3. Do controller does exactly what I wanted: Loads preset using program change messages and change parameters using control change messages. So, for my use case, I programmed it to press a switch to load everything at the beginning of the song (Iridium amp and cab, plethora board preset, flint reverb type, deco settings). Throughout the song, I press the other switches for section-specific changes (turn up the drive level and switch delay on solo, for instance). A long press on any switch summons up the plethora tuner.
I had no previous experience with MIDI pedals, but I found the programming using the online editor easy, straight forward, and honestly satisfying for someone who likes programming and general tech stuff. On the other hand, programming it on the pedal itself by pressing switches to scroll through the menus is not very user-friendly - but that's why the online editor is there.
When I first bought it (Oct 23), there were some issues with the firmware that took a while to solve, understandable when you realize this is such a small team. Now it is stable and working beautifully. The team, although small, is very active and supportive on Discord, quickly helping and solving any issues.
I am happy to support small companies with creative solutions, and I recommend the Bridge4 or 6 to anyone with a use case similar to mine (which just uses a small portion of the controller potential) or even for more complex scenarios since there are a lot of message types available on the unit. I always see creative uses from the community on the Discord server, so I am sure it can deal with many use cases.
