Hey Jim,
Thank a lot for your extensive feedback. I'm sorry I changed the rack from the original post, I was supposed to make an alternative rack. I like to experiment with sound design and music in different genres, but I primarily focus on sound design for film scoring but also melodic electronic music with interesting polyrythms.
I already have the 19" rack, but with no side or back walls, only the front. I made the rack as part of one of my bechtops where I have the Moog Grandmother on top. I also have the µZeus power module and one 19" Eurorack from TipTop audio. I do not have a back panel to connect a larger power connector unit, but I guess I can build that later when I expand the rack. It's a great idea to avoid all these power supplies in the panel itself, but for the first row, and beginning of the rack, this will be the supply for now.
Thanks for the tip on new veils, it looks great, and I love to save some HP :) It has been difficult to plan and imagine what I would need with basically zero experience, besides playing around with the Moog synth. You're right, I dont need the input module either, hehe, and probably I will not use instrument input very often anyways.
Fot the mixing, I was looking first at the Roland 531, but it was so big, and I thought with the Addac, and a simple output, I would have the option of using the addac as a VCA as well as a mixer. If I went for the 531 I would probably not need the X-pan, but I really liked the ways to produce interesting stereo images from the X-pan, and I really want it, I think.
I will look into the fx aid xl, I was never sure about the dual fx anyways.
Cheers!
