Fixed racks are neat! I keep a main jamming fixed rack, it’s a 128hp*18U monster however, so I can’t submit it as-is and will make a tiny one for this challenge. While 128hp isn’t a standard eurorack size, it happens to fit perfectly on my 1080p tablet display at 100% zoom - it’s built around a real hardware constraint I have rather than one inherited from real hardware.
