Thanks a lot for the advice plgrade. I should probably have been clearer that i will most likely sell the lifeforms rather than expanding by moving it out the rack - which obviously impacts what I’d put in it’s place. Nothing against the sv1 - Just had it for a few years and looking for a change. I’m filling this rack at a snails pace but I suppose I should get planning on what will fill the space. The new Tiptop/buchla 258t looks tempting!

I think you’re right about the size of the ATN8. It’s a shame but looking at how tightly the knobs are spaced compared to the stages makes it look like it would be a pain to operate. I’ll have a look at the modules you suggested when I have a minute and get planning again!
