cv 1/8 to AE cables?

The master module has convertors so you can patch the cables into it and take the output from the patch point. There are two cvand 2 audio. There's also the interface module.

Just to add my few penn'orth here (I hope I'm not trying to steal anyone's thunder), but I'm a newcomer and this is what I use.

I've mostly been using my AE while stuck in bed (as I'm disabled and bedbound a lot of the time). So I sit it on my knees, with a 3.5mm terminated lead connecting to a stereo. I stick that in either "audio 1 I/O" or "audio 2 I/O" on the Master I/O module. This amplifier is then accessible by using the top two sockets on the pinout connections. That's it. No switching or any other messing around. It's effectively just a fancy adapter.

I also use the other audio I/O for connecting the audio IN from my Minibrute 2 or Microfreak, for example and routing those same pins into the mixer module.

I hope you understand my clumsy description.

But, purely for ease of use (as I wanted to add more inputs), I bought the 4I/O module which does this same job, but offers 4 more I/Os, so I now have a total of 6 to play with.

 

you will need to have one one 3.5 mm jack connection capable of dealing with cv per incoming cv. So if you have two master modules then those provide you with 2 CV connectors per module and that leaves you with 4 income CVs that can be processed independently in your AE modular.

Absolutely, and your master module can do the same in absence of a 4I/O module.

Exactly, if you come from MIDI it's a weird thing this CV control. However, once you get it, it becomes second nature and is IMO more flexible than MIDI, but you can of course combine MIDI and CV if your external gear can do both. Unfortunately, the MIDI implementation on AE side is either rather limited, you can either specify 1 midi channel to which it will react or make it react to every midi signal received no matter what channel it was sent on. Perhaps one day there will be a dedicated  interface module that can handle multiple channels and not only receive MIDI but also send it.
