I am finally switching from VST2 plugin versions to VST3 ones, but I encountered some strange stuff regarding automation track.
Actually, to be honest, I am not quite sure if this really has anything to do with the VST2/VST3 switch, but anyway: let’s say I have some automation on some of the VST2 plugs (in my case it is “khs Pitch Shifter”), but when I copy that automation and paste it into the same plugin of VST3 version, its values are not absolutely the same because for some reason Cubase 12 decided to “measuring” the values in scale of -infinity to +6.02 instead of original VST2 automation values between 0 and 100.
So is there some hidden parameter I need to set in C12 so that it would copy it exactly as it was on the VST2 automation track?
I am also adding additional picture of both automation track, that is the original one for VST2 version of the plugin and the copied one below it for the VST3 version of the plugin…as you can see shape is exactly the same (that is automation values at exactly the same time stamps), what differs is C12 interpretation of the “filling” of the shape and beforementioned different scaling.
Might be…not, probably, cos now as I look at the two automation tracks (newly added picture above in main post) I see it is most probably C12 “thing” as it pasted the copied track differently: it looks to me like the filling is reversed for some reason.
The plug-in developers would know for sure. To me, it looks that the VST2 version parameter takes absolute values, while the VST3 version takes relative values, around a center value. The deviation from the center value is filled. (Similar to how pan automation would be for example)
I don’t know what this means, but seeing that there is a difference, no matter how small, I wouldn’t expect the same behaviour.
But how come that the plugin itself dictates the main application in which way it has to write its own internal automation values???
Sure I may be wrong, but AFAIK this is INTERNAL APPLICATION BEHAVIOR, that is when I copy value of the same type of parameter it is pasted in exactly the same way regardless of plugin’s internal interpretation of the value (which would be the case if the VST3 version somehow changed that interpretation)…or not???
As for the e-mail: in fact, I did wrote them once but to this day I received no answer at all, so IDK.
it seems IT IS NOT any sort of “default” C12 behavior dealing VST2 plugs vs. VST3 ones (tested Softube’s VIntage Amp Room VST2 vs VST3 versions - no problem, automation value is pasted exactly as expected)
it seems to be SPECIFIC PLUG(S) “PROBLEM”, like those kiloHearts plugs, but not all (gee!): it ocures with abovementioned “khs Pitch Shifter” but not at all for “khs Distortion”
YES, it is the same behavior with the specific VST2 on another newly created track: when I insert VST2 version of the plugin, that automation data it is pasted correctly as on original, but when I insert VST3 version of that plugin it is pasted wrongly again (and I talk about the specific plugin here, namely “khs Pitch Shifter”).
Thus most probably it seems to be kiloHearts issue, unfortunately for me, ah!
It would be great if anyone else using kiloHearts plugs could test it too so we would be sure for 100% this is the case.
