  • ViPro - looks like the Controller curves have changed

    I am just trying ViPro with the demo version. Lots of awesome stuff!

     The adjustable controller curves have changed - I can't make them as flat at the top as they are in VI. I liked that to add just a little bit of Expression smoothing to linear velocity cross fade settings (both on Ctrl11). It is not only the display that changed, the curves sound different. With VIPro, the flattest setting, which is displayed as 0.20, results in a velocity reduction that is too strong. Is this a deliberate change? Is it possible to match the previous curves?


  • Hi Wolfsterik,

    everything is possible in software, as our development team tends to say. 

    We´ll look into it.

    Best,

  • This ^^^^^^^^^ must explain the CC fader discrepancy Macker has been trying to point out recently.

    From the looks of it, both ViPro and Synchron are currently squaring the results from CC7 and CC11 faders (and probably other controls) when applying attenuation to the amplitude, which means when the Volume control curve is set to flat (ie, 1.0), its not really flat.  Its actually exponential with a simple square (amplitude^2).

    Was it flat before 2010 and got changed to non flat somewhere?  I've been trying to make sense out of the control curve adjusters in both Synchron and ViPro and can't make any sense out of it at all.  In ViPro I'm not even sure what the numeric value means, from a range of 0.20 - 5.00, but what does this value mean?

    with a setting of 1.0, showing a linear line...the actual amplitude response is not linear at all, its amplitude^2, which doesn't match the graphics.

    Setting it to an extreme value like 0.20 might overcome the squaring a little bit, making it flatter, but near as I can tell its not possible to make an absolute flat line linear response with the CC controls in Synchron or VIPro due to some internal squaring that is taking place somewhere.


  • Wolf, I can see and hear what you mean. The general controller curve won't go very flat, and nowhere near as flat as the Velocity control curve will go. If it's been changed recently, yeah that would be annoying. Can't honestly remember what the flattest adjustment of the general controller curve used to look like a couple of years back - haven't used VI or VI Pro in any great depth since then (but just blindly updated them as and when). Nothing comes to mind right now as a workaround for what you have in mind, sorry. Hope VSL agree to change it back if it has indeed been changed.

     

    [Oh btw, if Smiffy should start chiming in big time on this, it's best just to ignore him, lolol. (My fellow Brit Beano comic fans will of course know that "Smiffy always gets it wrong"). I've attached a pic and his profile, just so you'll know him lol.]

  • Note this applies to synchron also. It’s possible that whatever vipro is doing since 2010 is also carries over into synchron. Both players provide the ability to adjust the curve in a similar manner, but vipro has a bigger and nicer curve editor that actually displays some kind of numerical value representing the curve. But they appear to have the same behavior. From the above it seems that when vipro came out the default flat line “linear” curve was not actually linear compared to previous Vienna instrument player. Macker I believe the non linear response you have been observing in synchron’s cc faders is due to this. What I don’t understand is why a non linear fader response has a straight line image on the GUI control. This must be an oversight that has slipped through the cracks until now and ended up in synchron also. Amplitude is being squared somewhere in the signal chain after applying the cc using whatever curve the user has specified or straight line by default, but the amplitude squaring produces non linear fader response anyway
