    Help! Pls. Update Midi support, all other midi apps work except this one! Lollipop 5.0.1 Shield Tablet. Thanks!

    App has a bit more latency on an Asus TF-700T than I can be comfortable with for prolonged periods, but it is certainly convenient to not have to connect to the PC to play the piano. Piano sounded remarkably good. Will try on my Note 3 via OTG and see if I get better latency. Note that I don't fault the app for the latency. Android and real time audio aren't exactly synonymous. A good app and wort

    I could have pressed refund but I believe more can be done. I need pitch bend wheel on the app and modulation wheel. So I can use it to control some stuffs on Cubase. I need more sounds. Dx, Vibes etc.

    This app works fantastic with Android 5.0. I'm using my Nexus 5, an OTG cable and my M-Audio midi keyboard. With the latest Lollipop update I'm getting audio latency around 30ms which makes midi playback FINALLY possible. This app sounds great and connects as soon as I plug my midi controller in. The only issue I had when first setting up was turning off Stickmount which was trying to look for

    It is probably the best piano out there . only think that let's it down is latency and buffer issues . when multiple notes are played bad cutting occurs .

    App is great, but really let down by Android's high input latency.

    I love this app, but lately I have been turning off my WiFi to save battery life and I have a question, does this app use the internet to verify it has been purchased? Because i have been getting a message from the app that says it is not purchased, so I then have to uninstall and reinstall the app to use this, please look into this when at your convenience, thank you.
