Hey Oli, welcome to the friendliest Amiga site on the Web!
Your comment about efficient design being what the Amiga is all about really rings true for me too. It caught my eye, as my company name is "Efficient by Design". Actually more than one company as I am adding another branch (video production, weddings, events, training, etc.) to my Construction Consulting, Building Design, CAD services.
If I can just get my favorite CAD program ported to AOS4, I could probably get rid of Windows in my home and office completely.
Again, welcome and I'll be looking for your Amiga music knowledge on the forums in the future.
