It looks like the Attack Level (AL) parameter affect the filter types. It should'nt. It shall only affect the level.
And it looks like it also has something to do with the fact that you can't switch parameters - including the filter type parameters - on and off like this thread - " Cannot enable or disable filters:
http://forum.arturia.com/index.php?topic=87962.0 " - is about, because the AL by mistake affect the filter types. So this AL bug also proove the bugs in reported by Jeffbart in the linked thread is very important.
I agrea with Jeffbart that CS-80 is pretty much useless at the moment. Unfortunately not the only VC5 application to be.
CS-80 is also useless because of the aftertouch and hold issues that has been reported.
Unfortunately it looks like VC-5 was out way to soon. You need to step up very fast Arturia.
Also in CS-80 it looks like there actually are technical issues that is the reason why the applications sometimes sound thin as i have posted about from when VC5 was released. It's filter issues.
Arturia - Time to be resonsible. Not perhaps sometime in the future. You should have been a long time ago allready.
