How to emulate the NM1 FMA input behaviour ???

[3phase]

I wasnt able to get the same exponential behaviour on the G2 lin FM inputs..regardless what i tried.. i had to give up...

Somebody else knows how to do it ?

I am not exactly sure this is what you need, but I was able to approximate
y=e^x, using the formula:

e^x=1+x+x^2/2!+x^3/3!+x^4/4!+x^5/5! ...

input marked x (yellow)
output marked y=e^x (yellow)

I checked for 3 simple values:
e exp -1=1/x. (returns the correct value.)
e exp 0=1. (returns the correct value.) and
e exp 1=e. (returns the correct value.)

Hope this is helpful.

To my knowledge the FMA input is a linear input with twice the sensitivity of the gray input.

Thanks.. i will try it...

and twice the sensetivity of the grey input ???

I know...but i still have the problem to interpretate 2 as sensetiv...because all the inputs are scale from 0-127...are talking about the exponential curve?

Now you got me confused ... I was recalling some dusty knowledge from my head .. let me try to undust.

From page 35 of the Classic manual :

FREQUENCY MODULATION (FM)
A signal routed to an FM input on a module affects the pitch by modulating it linearly in the frequency scale (see figure below).

[the figure refuses to be pasted here]

Twice as sensitive ... ah right, you were refering to the knob characteristic probably - the knob has an exponential curve (type II, explained on page 31 of the manual).

And I meant that where the grey input gives a certain frequency deviation (absolute, in Hz) for a certain input value the FMA input will give twice that deviation when the attenuator knob is turned fully open / clock wise.

The grey inputs are linear FM inputs as well - although the manual doesnt tell you so.

(The manual I used is http://www.clavia.se/nordmodular/Files/NM3_0Ed2Manual.pdf )
