BT MIDI-Out Demo

PLEASE NOTE: Requires special hardware (see below). This app is NOT COMPATIBLE with Bluetooth MIDI interfaces available on the market!

Demo version! Plays only one internal MIDI song. Find the full version here: http://play.google.com/store/search?q=pub:hdop

This app plays MIDI files (Type 0 and 1) via Bluetooth on a real MIDI device. A Bluetooth-to-MIDI interface is required. Two examples can be found here: http://www.protopage.com/hdop001

The MIDI files in a directory can be played automatically (all or single, with or without repeat). You can adjust Speed, Velocity and Transpose "on the fly" (Transpose only when STOP). A single button press restores defaults (DEF. button).

In addition, each channel can be muted/unmuted. The volume-down (volume-up) key mutes (unmutes) all channels. Active channels are green, deactivated channels are red.

In settings "Control Change" and "Program Change" messages can be suppressed, to preserve the manual settings of the MIDI device. Max. 100 tracks can be played. You can insert up to 5 seconds of silence between songs.

Bluetooth-to-MIDI interface: The interface used has to be set correctly ("Direct" or "Buffered").

Buffer depth: This value defines how much MIDI data is buffered in the external controller. The higher this value, the longer it takes until Speed and Velocity changes become audible. The controller passes the buffered data on to the MIDI device with exact timing, so that timing variations caused by varying CPU load are effectively eliminated.

Bluetooth device selection: The selection can be limited to device names containing a particular string, defined in settings. If only one device is available, it is selected automatically.
