I'm also strongly considering selling my KSP. It' s never quite fully 'stable', particularly when acting as timekeeper for both a DAW and modular gear.
But my major problem is that we still cannot edit sequences in the Midi editor. Simply staggering that their non-pro keysteps can do this, but we can't. I'm rarely in the mood to manually recreate sequences from my older material for performance, and I'd really love to be able to properly / visually edit the sequences of newer stuff I've composed on the KSP itself. This acts as a barrier to fully using the KSP.
Oh, and give me more than 64 steps in my sequencer please. 128 would be such an improvement, and again would remove some of the instability introduced by chaining sequences together.
The unit is so promising, but some key design flaws and the inherent instability makes it very frustrating to use (at least in my use case).
