Sometimes, when you work with a lot of Midi Apps, hardwares too, you can be a little bit lost with your connections. And when something goes wrong, you can wast a lot of time to understand where you have made a mistake. (A computer never makes mistakes). At this moment, you have one solution: Midi check. You launch the App, check out that all your Apps or Hardwares are visible. Then, you can select one of your App and use the built in keyboard to test it (MIDI notes). You can also send volume and modulation control messages to this App. Another page will record all the Midi messages send from all your Apps or Hardwares. At the end, in 2 minutes you will be able to understand what is going wrong and fix the problem. Midi check is very easy to use and a Must Have for all iOS musicians! A Killer App!
