I would like to preface by saying I'm so incredibly grateful for the recent update. I went from using my KeyStep as an occasional Step Sequencing Bass Machine to having it be the center of my portable setup. I'm tempted buy another.
Anyways, the sequence mode transpose feature still frustrates me. As it is now, you set a key through the control center that acts as the key signature you recorded in, and the farther you get from that note the farther it transposes it. I set mine to C3.
But if I record in A, and press D3, my sequence is transposed to B. I have perfect pitch, and this makes it very difficult for me to transpose on-the-fly during a live performance. The only solution I've come up with is recording all of my sequences in C, but that's definitely less than ideal.
Oh, not saying the current transpose mode should be replaced; just able to be toggled in the MCC.
