<p class="MsoNormal">3.5 mm was already the de-facto standard by then. But half of the manufacturers ended up using one polarity and the other half chose the other, which potentially makes MIDI devices incompatible, unless special cables/adapters are at hand.<o:p></o:p></p>

<p class="MsoNormal">In Elektron's Model series of instruments we implemented the TRS MIDI In to accept any polarity (passively, using diodes!), and a setting in the UI chooses between the two polarities for the TRS MIDI Out. Has this been done anywhere else?
I've always felt that it perhaps should be published as an official application note, a suggested implementation superpower for other manufacturers to pick up. :-)<o:p></o:p></p>
