I have some comments about the website and presentation.
The primary reason I’m interested in MOD is because it’s free/libre/open technology. I will be quite upset if I were to find out that core stuff or much of the ecosystem turns out to be proprietary in the end. Why is there no reference to Free/Libre/Open values on the website?
There are tons of guitar and related effects units out there. There is no free/libre/open one yet or even close. This is the distinguishing factor here. Why not emphasize it‽ Put stuff on the website and elsewhere talking about how this is such a revolution liberating the effects chain. You’ll get tons more interest and widespread communities who care about this will suddenly take more notice.
Ideally, publish the core stuff about the hardware itself and get it certified as Open Hardware by the OSHWA http://www.oshwa.org/ but even short of that, just emphasizing that the software is free/libre/open is a big deal and a big marketing feature. And not mentioning it makes it almost seem suspicious, like you’re trying to hide that it’s GNU/Linux and FLO software for some reason, and that leads to less trust from audiences…
On a side note, your videos would be better if they had music that sounded like it would be played with the MOD rather than being just some programmed stuff that doesn’t use much of the value of the MOD.
