Hi Sacguy71,
Great to hear that your new modules have arrived and are installed and working, luckily without smoking them up into thin air :-) Nice demo by the way, it's clearly you enjoying your modules :-D !
Regarding the Elektron, I have myself the Analogue Four (A4) and I had MIDI issues as well, till I discovered...
The opening in the Elektron housing for the MIDI plugs isn't very large, so you might "think" you had plugged in the MIDI plug into your Elektron but though it fits "half-way" it doesn't really necessarily makes electrical contact... I had to buy a cheap MIDI cable with a cheap plug (hence as thin as possible) so the MIDI plug would fit into my A4 and then it worked.
I am not saying you have the same issue but since you mentioned: "and then no dice!" I thought perhaps you have a similar issue, at least it might be worth it to have this checked.
I like Elektron stuff but I do hate them for creating ridiculous small openings for the MIDI plugs :-(
Have fun with your modular system and kind regards, Garfield.
