Hi Ted,

I'd have to play it in length to determine which styles are more suspect to the glitch. I just noticed on several songs and had to already work around some changes - but...it might just be me.
Without dedicated fill buttons, you're at the mercy of this
engaged "fill" button. It annoyed me enough that I disabled it only to find there was no way to "fill" - kinda wierd, IMO.

The 3X is no angel either, but having so long and being careful, I really never have a problem filling and I would miss the 4 fills - awesome feature. Now that I'm thinking, I didn't try the toggle feature on the 1000, but I'm surea it has it? I use that all the time.

I'm extremely critical of everything vs my 3X - so my assessment is probably not fair.

good luck to you
