I've noticed the same thing and was going to report it, though I've only played with the chord sequencer once so far.
I also found stuck notes were a happening a lot more when using the chord sequencer, usually on the pad. I almost never get them without using it.
Another thing that isn't necessarily a bug but would be nice to implement: when the drone is set to change based on chord, it doesn't change until the next note-on in the drone (so, once per bar or beat, depending on the drone pattern). I think the "pad quantize" setting should apply to all parts, or the drone at the very least... you want drone and pad to change together in most cases.
