This one worked, the other one didn't
David NL

Simple as that. Writing a program to monitor MIDI data flow in a network doesn't seem like it should be like rocket science (although I could be wrong about that; it's not my area), so I expected the other monitor I tried (MIDI Monitor) to work. It crashed almost the instant MIDI data started to flow, over and over again. MIDI Wrench listened to the network, showed me what was happening, and stayed alive. That's all I needed it to do. Thanks for creating a product that does what it says! The rest of the interface is attractive and easy to use. The control knobs pop up to full-screen size for ease of manipulation and feature numeric readouts so you know exactly what MIDI value your setting them at. Basic ON/OFF buttons for pedals and an All Notes Off button to deal with "stuck keys."


Awesome

An essential in this "Wild West" of mobile MIDI.


Great app - please update for iOS 10!

Nothing wrong with the app, but a pop up occurs on my iPhone 7 saying that this app needs to be updated by the developers and hence may slowdown my phone. Love the app - hope you're reading this! Please update it for iOS 10!

Why, Christian, do you refuse to maintain your apps? This is a very good, useful product that could be better still with the kind of active development most successful mobile-app developers embrace. You let JACK die for no obvious reason, and other apps just flounder once system versions change. If you worked on these apps - especially things with the potential to be useful to so many people doing music on this platform, like this and JACK - you might build communities that make the effort worth your while. Please consider regularly scheduling time to maintain your software.


Great app

Does what I need

I am using several midi compatible apps on my iPad. Each time I come back to my piano to do something, the first thing I do is power up my piano, turn on Bluetooth on my iPad, and open MIDI Wrench to reset the iPad connection with my piano's MD-BT01 Bluetooth adapter. It works every time. I do see that this app does a lot more, but I don't need any feature other than making the connection. The only reason I am not giving this five stars is because, if I take a break (20-30 minutes?) without turning off either my Piano or my iPad (and my iPad is set to never auto-lock), I sometimes discover my connection has been disconnected. Then I have to reopen this app (still running in background) and reconnect. As long as this app is still running in the background, it should wake up often enough to keep that connection alive.
