- You are doing that, though your inability to take criticism without being defensive will limit how much people want to engage with you. People aren't going to engage with you if you are demanding and difficult in ways that aren't called for.
- You are doing that and people are responding to them.
- This process cannot be done without you doing the majority of the work in testing module types, trying things one step at a time, maybe visiting music stores to see what you can try. VCV Rack and Hexen are around for free, and you can read module manuals to better understand what they can and can't do. Only you will know what works best for you, and figuring it out is part of the fun. If you just want an "all-in-one band in a box", they already have that, and it's called a computer.
If you want to flex your creativity, play some music. If you need help with something, ask. If you just want to chat, maybe see if there are any Discords you can join or go on Modwiggler. In my experience, conversation here seems to be limited to people posting music or asking specific questions. If you already have "very specific taste", you might not need to share your ideas before you start working on them anyway. Frankly, your behavior here is pretty alienating and will not turn this place into a great place to make friends. Being a good listener and taking the feedback you asked for well even if it doesn't necessarily fit your goals will work much better.
