Thanks for your replies, i'm starting to get the concept. So if i got a radial proRMP (if i can find one in the UK), i would go out of my soundcard with a jack-xlr > into radial with with impedance conversion > as many fx chained as i want > back into my s'card preamps back to high level onto seperate cubase buss. Correct?
Do i have to DI before preamps or will my soundcard do that automatically (audiofire 4 is on order so i cant check)?
Also, is this exclusively about avoiding noise, or can i actually harm my gear if i don't match? I'm sure on youtube people just chain things up any old way.
Are analog synths line level (specifically moog voyager)?
I know these are dumb questions, but i have tried to google them with no luck, i need peace of mind with my gear.
