TL074 is a quad, not a dual.  I would not use a quad to share functions that 
I wanted not to interact... like two different
VCOs for example

>What are the drawbacks (if any)?

I think the TL072 ans TL082 are the same. They say the TL072 is
a low noise part... but I don't see a data sheet difference.

>Would you recommend sticking to the TL082's?

No

>Is the noise ratio better when using the TL072/TL074 's?

So they say....

>Is it important for cerain modules only?

Use sockets and decide for yourself. I like the AMP Diplomate dual
leaf sockets in tin/lead plating (you don't need gold... no benefit)

>In how far is the sound affected?

IMHO you can't tell the difference.
