It doesn’t have enough faders.
in your opinion, a crucial distinction!
Please, is there any way to “chain” two 16n or Sweet Sixteen, so that they appear on the i2c bus as one device with 32 faders?
No, sorry.
But: both 16n and @M4ngu’s Sweet 16 are open-source, from firmware through to hardware, so perhaps you could investigate what it might take to do that? If you’re asking me to do it, it’s not a feature I have a huge amount of interest in.
I know I regularly write “it’s open source, why don’t you try?” on lots of these posts. I’m not doing that to be passive-aggressive. I’m doing that because that’s exactly one of the advantages of making open-source projects: people can investigate modifications that are really valuable to them, even if the original maker doesn’t care. Some of them make things like the Sweet 16 or Berlin Modular version that other people prefer.
And: I’m not a trained EE. Everything I learned about electronics, I learned from open-source designs and other resources; Tom Whitwell and Émilie Gillet are largely responsible for my electronics skills. (Hell, everything I learned about code I learned through open-source products, tools and languages!). I know many people will bounce off that suggestion, but some of them stick it out and end up with new skills, or something unique that they’ve made, or something other people will like.
OS isn’t just a neat way of getting PCBs and building things cheaply, it’s a way of joining in, making what you want, and sharing. And that’s why I’m going to keep writing “it’s open-source, have you considered trying to make those modifications yourself” every time there’s a feature request I don’t think is critical for the OG 16n.
(FWIW, I think building a Sweet-32, rather than chaining two, might be an easier approach, but that’s just me. It also means you can’t, say, have two banks of 16 at different locations in a rack, but that appear as one 32-fader device.)
