I have a question about the MIDI keyboard notes on my two MIDI-capable instruments. I have a Titano acoustic accordion with a simple MIDI system that transmits treble, bass, and chords (no bellows dynamics). Using the MIDI Wrench app on my iPad, I found that pressing the middle C key on the keyboard triggers C3. On my Roland FR7, the same key triggers C4 an octave higher. This has been problematic, since many of the instruments sound too low when I use my acoustic accordion with MIDI. I have been able to overcome this problem on some sound modules that allow transposition, but I wonder why these instruments aren't sending signals in the same octave? Is there a way to correct the problem with my acoustic MIDI system without having to purchase new hardware?
