Haven’t tried that, but I can well imagine. Certainly if you had a bright sound and you p-locked the cutoff low on a step, you’d hear a pop of the previous sound before the cutoff dropped. Roland have fixed a number of disappointing features on the 707, but this one is still pending, as I belive is the S&H LFO being reset when synced to note-on. I understand Roland are a big operation and they clearly prefer to do things carefully and methodically, which isn’t a bad thing, but it’s unavoidably frustrating when you see smaller companies pushing frequent big fixes and minor versions…
