Perfect for what I wanted! I was looking for an app that would allow me to use my phone as a drum pad MIDI input device (so I could record drum parts "on the go" without having to drag my larger drum pad MIDI controller with me). This did not disappoint. It has an intuitive interface without having overly complicated settings. The app even shows a helpful reminder to connect to the MIDI device on your computer if you try to open the drum pads screen without having connected. Great app!

Awesome app. As a feature request could you, please, add a 'latch' button. i.e. when latch is active single-pressing a note makes it sustained indefinitely and the note is also highlighted as pressed. A second press is required to release the note. Chords could be formed by single-pressing individual notes to sustain or release them.

That's a cool idea. Thx for the suggestion. Maybe I'll get around to adding that some time. As the app is now, you can add a sustain button and double tap it to latch it on. Maybe that could get you halfway there?

This is a special app that just keeps getting cooler the more settings I try out. I was able to customize the grid to a 8x8 layout and basically had the software version of my favorite controller with even more customization in scale layout. I can just relax and practice on my tablet now instead of hauling the heavy controller and laptop in my room and setting up the DAW. When I put it in MPE mode and realized each finger had XY control..mind blown. I'm using fluidsynth to test it out
