It's good if this finally will be fixed. It's a old known and reported issue like many of the things jeffbart with good reasons report. It's not picky to report this. It's a desire to get the product it should be, and that's paid for.
Off coarse things should be in tune from the factory. And when in tune things should equal a even number and not a decimal.
There are many things reported for the old applications that's the same in the new, and that's a clear indication that the applications is not rewritten and that there are many things to fix in the old too.
Arturi please check and fix everything like technical issues, Preset and template issues including tuning, wavewidth and VCA, master and velocity, aftertouch levels/ volumen etc for all presets, and GUI's in every aspect. You should have gone thru every detail for VC5 and also delievered those fixes for VC4. But you hav'nt checked things yet. Please do it now, so the product work as it should.
Of coarse things like a working aftertouch and a working filter and alike is more important than a typo. But everything should be fixed for each application.
