as already reported, the astable filter / attack still exists in Beta3. A good example to see what i mean is to load the preset HARPICORD-01 from Keyboard Sub-Bank from the M.Lupo Bank. Just play some single notes very fast and you get a BIG amount of high peaks. Same happens for most of the other sounds what makes the CS80V pretty useless (at least for me) atm.
