I am writing up a tutorial, long story short i need to know the what are the default two octaves these 2 octave midi keyboards usually transmit out as i do not actually own one at this stage.
Alternatively you can copy and paste 2 midi messages here from a midi monitor like midi-OX. One for C on the first octave and another for C on the second octave, I can work it out from that information.
My keyboard (an Axiom 25) has two buttons for shifting octaves up and down, and I believe it’s on octaves 4 and 5? It’s totally arbitrary though, and I’m sure most two-octave keyboards have this feature.
