Hi,
About the volume.
Yes many sounds in VC5 are lower than in VC4. I actually find that good, as i really think VC4 often had to high output - way over 0 db sometimes. I still find the leveling between patches could be better. But i rather have a output that is a little to low, than one that blast my ears. Far to many softsynths had in my opinion a way to high output and is only high to make it seem like they sound better than they do just like when they use to much effects. I find to high output and to big variations in output between the presets very annoying and dangerous for my ears and my equiptment. Around -12 db on a digital level meter is for me a fine standard that allow some dynamic.
That's just my opinion.
Also it's clear that the output in VC5 can be way weaker using the same settings. Perhaps this also can be because the low end of the sound seems to be reduced - and that to much i think.
About the sound.
I also find the sound in VC5 in a way to be thiner. There is not so much low end, but the low end is to me more defined in the timbre. However i would encourage Arturia to look into if the low end is comming thru like it should. I feel like some body is missing. Especially in MINI V i have noticed it.
As there are so many bugs in VC5 i have'nt worked that much with the applications. So the jury is still out, if i think the sound is better or worse than in VC4 or not. I do belive at least some applications can have benfitted of the new sound and some have lost some of the soft character they need for some sounds. Perhaps i will like all applications, when they work. But i think there still is room for improovements. And i think Arturia could nail them all, if they put some passion and will into it.
I'm not sure if Arturia has gone to far away from emulating. For instance i have tried to recreate a factory preset from Jupiter 8 using the same setting as on the hardware synth. the parameters is far of. I feel this is also true for other applications. If i try to create a known sound from a patch sheet, then the parameters os far of. Again i shall fell like the application work to spend the needed time to be sure if i can make the sounds i wan't. It's possible i can, but the parameters are not like on the hardware.
I still use the old applications. And i will use them for old projects and sounds. I fell like VC5 is different. That's also why i think the VC4 applications should be bug fixed. Also because they are bought to be working.
I would like to hear what you mean by "thiner" sound?
To me MINI V has changed a lot in the sound. The Filter Emphasis and the Amount of contour has changed a lot. It's like the low end is'nt strong so sounds need body and also softness for that matter. So some of one side of the Minimoog character seem unfortunately to be reduced. But perhaps another side has been improoved. Not sure yet. But i would like to be able to produce the soft sounds anyway.
