    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.

    I have a Note 1 and Note 8 and Alesis Q 49. It work both Notes. There is just a delay when playing keys on the Alesis Q49. I will just await if there are some updates to correct this issue.

    Is there any way to record via usb? Maybe create a midi file from an external keyboard?
