But information from the system did not populate visibly on the device other than the number of buttons we had to play with, many of the functions were clearly not hooked up, there was no visual indication in the app of what preset you were working with at the time, it should be much clearer when the app drops the connection… there is very definite room for improvement here, particularly as far as the user interface and friendliness go. Once we had the connection established, it worked well (though without top-notch wifi you will likely experience lags from time to time, which can be annoying). I was able to buy and configure the app to work on the system relatively quickly, though I would not want to try doing this as a non-technical person. Pretty good - but as the only option, could use some workĪll in all, what this app does is awesome - and made it possible for us to run a reasonably impressive light show for a Phish tribute band despite the computer being in a back room.
