Pretty Good but...

Love it for playback and editing, but the instruments just barely sounds better than the Windows and Quick Play sound font.

Doesn’t work on iPhone

A friend told me about the app so I downloaded it to my phone and tried repeatedly to upgrade to the pay version so I could play my entire midi files but could not find a way to get it done. I finally tried it on my iPad and found out the problem was that the settings button does not display on my phone. I paid for the full version and downloaded all my files. I went back to my phone hoping everything would be there because my iPad and phone are on the same account. But nothing was there and my phone still had the free version. I opened and closed the app and even redownloaded it so it would reset and transferred all my files but had to do them manually. I finally got a link to upgrade to the paid version but was expected to pay a second time so I declined.

Easiest to dnload & manipulate midi tracks

Bern using this app for over 5 years now. Produced excellent tracks on this app. Still going strong ! Most friendly and versatile midi app for my iPad and iPhone. I appreciate the trial version before I bought it! (Apps should all be trial versions before purchase!). Developer did good! I downloaded all my midi files from windows pc too. Also, app can now transport my creations to other midi apps and emails for others to enjoy.
