Perfect midi recording and play back app – MIDI file player Review

I searched for a long time to find an app that could simply record and play back midi files. This app fills the bill nicely. I use an IRIG midi to lighting device and connect it to a Rodgers organ. The app records both the on/off commands but also the SYSEX commands which control the organ Pistons. The app can also transpose and change tempo. The latest update now supports Bluetooth midi devices and I will be buying the Yamaha MD-BT01. Hopefully this will work.
