Silent way calibration with modular oscillator issue

I'm trying to calibrate as best as possible the 'Voice Controller' module from Expert Sleepers with a simple sine wave modular oscillator and I get a usable pitch signal only on 2.5 octaves. I'd like to have 4 or 5 octaves !
It's a bit special and people who don't have Silent way won't be able to understand what I try to achieve. But maybe some people here is using the 'Voice Controller' module and have better result... Have a look to the curve I obtain :

As you see, the longer part is not very long and it's not straight, which means the pitch is far from be perfect even on those poor 2.5 octaves ! A good curve should looks like this (but that's not mine !

) :

I already tried to low Voice Controller input & output for calibration --> no luck. I really don't know what to try to improve it.
Silent way works perfectly thru asio in Scope, so there is no reason that only pitch CV signal would not work as well via asio into Scope, no ?
Does someone could give me some advice about this specific question, around here ? Thanks !

V/Oct or Hz/V?
Try attenuating the oscillator output to avoid any overdriving of the calibration routine.

Thanks for the advice ! .... But I already tried that. It just shiffted a bit the curve but with the same pitch range : around 2.5 octaves on the biggest curve part...

I'm a little bit confused...
The muffwiggler links is interesting but I'm not able to register to this forum, I give always bad answer to the robot check question about an animal or about a synth ! Now, it refuses to let me try again !
And the text files they are talking about on the topic are not available for non registered people.

DragonSF : I don't understand nothing of what you're saying !

I'm wondering if I'm not completly idiot...

If someone has the privilege to be registered on muffwiggler, please, follow the link and check if the text files from tomylee are still available ! Thanks ! I'm impatient to see how a good calibration file for Modular looks like !

Yahoo !! Thanks a lot !!
How did you register at muffwiggler ?? I tried 10 times --> nada !

Thanks, Dragon, to take time to explain. As I don't have any hardware modular, I don't know the voltage value. But now, I get what you're meaning. The relation is linear...
I'd like to know the max voltage value on a modular system... Is it 10v ? So the normalised signal would be 0v --> 10v ? Right ?
... After checking in wikipedia, I can see that there are 3 normalised voltages : +/- 15V ; +/- 12V or +/-18V ! One has to take care to not feed a 12v max module with 18v ! Converters are needed to use several voltages ??
Software are less risky ! And I don't have enough space & money, anyway !
Anyway... ShogunSpy gave me the calibration file which works perfectly for all midi octave ! Very useful !

Excellent ! And with some Scope analog I/O and Silent Way, you can make your hardware modular synth play with Scope and vst's ! That must be terrific !

Bet that synth is a FAT Basrard.
