It is very sad that this wonderful app's rating which deserves a wholehearted Five-Star rating, is getting pulled down by users who are not aware of how to use it. There are two key factors. 1. As explained by Shola Smith, you have to set the USB configuration to Midi in the Developer options of the phone. 2. Then you have to set the "Receiver for Keys" in the app. Touch the down arrow to see the available options. If you have installed Fluid Synth by the same author, you will see it as one option. Select it. Now if you click on the keys, it sends the corresponding messages to Fluid Synth and the sound will actually come from Fluid Synth. Remember to turn-on the internal sound font for Fluid Synth. This app is not intended to produce sound. It just sends out midi messages. If you are disappointed with one octave of keys, hold it in landscape mode, you will get two octaves. Every one of the four apps by this developer is so tiny and yet so functional.

So far, the only app I've found that works as a MIDI keyboard! It's the perfect, low-cost substitute for a physical keyboard. Would give it 5 stars if you could scroll up/down the keyboard instead of being limited to one octave.

I used my phone with a USB controller and connected midi in on Roland U110 didn't trigger midi to hear the sounds out of the romper

It doesn't work, it doesn't make a sound, or perhaps I'm missing something here and have misread what app this is🤔

It works but you Can't change octave. Keyboard layout is horrible.
