Hi, and welcome.
Personally, all my analog synths (including my beloved 1975 Minimoog D) are plugged into an analog multi-channel mixer, and then directly to the line input on my Mac Mini. I then use Audacity software to record them. I will occasionally use some external effects like the EHX Cathedral stereo reverb, a Small Stone phaser, and a delay (either the one in the Cathedral or a Boss DD-7).
Hope this helps a little.
Alain.
Yeah, I wrote that a while back in response to another post. So why would you create a new topic with my reply under your name?
Do you have a question about it? Do you have an opinion about it? What?
Oh, and welcome to the Moog Forum. 
BTW, this set-up has changed a bit since that post. I now use a Strymon BigSky (replacing the Cathedral), and my new Mac Mini doesn’t have an audio line input anymore, so I have to use an external audio interface (Behringer UMC204HD).
yeah, that is a bizarre post!
I normally go Direct thru my interface, into Reaper on my DAW
if recording Voyager in stereo I use a rackmount Sony DPS D7 delay unit, which I like a lot
mono is usually a Fulltone Tube Tape Echo, or Roland SDE 3000. which is cool, as it has modulation
I want to try miking a speaker up, just for some variety. an old Leslie cab here I should fire up
