@Trismus For your 1U modules, whatever the brand of rack, you can think of the 1U to 3U format changers from Xodes. Like this one for example: https://www.modulargrid.net/e/xodes-fc313-28hp
@JimHowell1970 London and the few places I've mentioned are linked to so many of my memories of the 70s and 80s. Concerts, studio sessions, meeting all sorts of nice people, and even... camping (in the East London suburbs, because it was cheaper and above all a wonderful vestige of 60's philosophy, cool :)) Having said that, I agree, London, which is an extraordinary city, is not the whole of England. Like Paris, for France, London is 'the eye of the duck', as David Lynch would say: when you look at a duck, you look at its eye, even if it's not the whole duck. I played on stage for the first time in Margate in 1972 (piano, not modular). My heart belongs to Kent.
