Hi,  I own a Regina music box and a few other mechanical musical
instruments that have been MIDI-fied, and want to be able to play
them with MIDI files on my iPhone.  Is there an iPhone app that
can store a playlist of MIDI files and send MIDI to the "MIDI Out"
output on my iPhone MIDI interface, the IK Multimedia iRig MIDI?

I don't want some player that just plays back MIDI files on my iPhone
with wavetable files/samples.  Rather, I need the program to send
the MIDI signals _out_ to an external device using my iRig interface.
Does anyone know of an iPhone app that definitely does this?

I've already downloaded the following apps, none which seem to do
what I need as described above:

  iRig MIDI
  Sweet MIDI
  MIDI Player 3.0

Maybe I'm doing something wrong here?  Any help would be appreciated.

Thank you,
Mitchell Manger
