I own a Keystep and a Beatstep Pro and, after waiting due to it being backordered this summer, I finally received my Keystep Pro. To say that I was disappointed to find that I cannot edit and manage sequences using MCC is a major understatement!
I realize that not all users have the same needs, but, in my case, the sole reason why I wanted to replace the Keystep with the Keystep Pro was because it had the ability to store more sequences. I find it mind boggling that, with such greatly expanded sequencer capabilities, the ability to edit them onscreen is not ported over from Keystep and Beatstep Pro. The unit is well built and has many great features, but I am on the fence regarding whether I should return the product for a refund.
Please consider implementing this functionality!
