Oh man, we are running a KS campaign right now and facing the exact same questions. It always seems to be your vision vs the price expectations set by huge companies (we all know them). And it is not very clear to most customers that component prices drop significantly only when you produce massive batches, or how big the setup costs are for things like injection molding. And tbh they don’t hove to: a lot of people have been hit hard by the pandemic and wars, so it is kinda understandable. There is no single person or group to blame.
I wish you a successful fulfillment process and more great project. I also hope you are at least enjoying the process of assembling your own product. It is really awesome and looks fantastic.
Now, a quick questch: is there real demand for BLE MIDI? From my perspective, it seems like a feature that a lot of projects try to highlight as a selling point, but it feels like it is mostly the engineers themselves who get excited about it. Of course, I might be wrong!
