thought id give this topic a bit of a bump⦠as AE modular is definitely gaining some pace now 
its now generally available for ordering etc, with its own website, including shop https://www.tangiblewaves.com and also its own forum http://forum.aemodular.com (quite new, but starting to buzz)
there have been quite a few new modules since release including a great multi fx module, and tangible have still kept these affordable.
but Iāll concentrate on my experience with it, a kind of an updateā¦
touching on some comments from above, and also what ive been up to with it.
first patching mechanism, Ive not really had any problems with it at all.
though interestingly, Robert (Tangible Waves) is now shipping modules with āimproved socketsā and better patch wires.
support, I had a couple of minor issues with a couple of modules from the kickstarter ( I got mine very early) . Robert (tangible waves) support this out immediately, no fuss⦠and generally has been awesome in his support.
(also its noticeable that where needed, he is doing minor adjustment to modules to improve them)
eurorack, actually its operates pretty well, not only has 2CV IO as standard but there is also a 4CV IO module, to continue adding more (in 1 HP)⦠and they also now have a eurorack adapter so you can put it in a eurorack case - heres mine 
v/oct - by the time AEM was released, both the dual oscillator (2 OSC) and VCO were v/oct. the latter tracks better.
I truly love the sound of AE, its really great - and also its small size means its really portable, you can even run it off a usb power bank (with adapter)
what has surprised me the most, and led to loads of fun is its openness to DIY.
its cheap to create your own modules (and less fear of blowing things up due to the price⦠and being unipolar 5v, makes its much simpler than eurorack.
it really draws you into to experimentā¦
(the blank panels you get become really useful ⦠and the fact that a new case is 19 euro means no worries about filling it up!)
starting simple - here, I just chucked the Bastl Kastl into a module format (so gets power from AE) , and all the patch
points are already 5v so ājust works!ā (its fun to use Kastl as an oscillator )
the other thing ive been integrating is some more flexible modules (Im a software developer so love to bring software into the mix)
first was my Bela module
very simple, 8cv in, 2 cv/audio out⦠but bela is powerful, so you can run PD/SC on it, which is alot of fun
the today just finished a arduino module, (ok, not done the front panel yet !)
4 cv in, 4 cv (or lofi 12 bit audio) out, 4 buttons, 4 leds, 4 pots
In many ways this is basically the same as the Eurorack Ardcore, and in fact I reckon I can easily convert most of the patches 
so yeah, Im a big AE fan now, really nice to see someone doing something really different, and also making a great job of itā¦if you want to get into modular synthesis on a budget its unbeatable, also if you fancy playing with creating your own modules its great too.
Eurorack is still cool, and I bought a rack too⦠but its nice to have options.
(and now AE has introduced me to creating modules, Im now ready to buying/building eurorack kits to help keep the price down a bit
)
