Hey Cangore,
Thanks so much for the advice. I think you are right. I guess the Maths I have fulfils some of those functions, which I won't get with the Random Source DUSG. Interesting. I've not heard of the SSF Toolbox. That looks ultra useful. Perhaps that and Shades might work. I take your point about Magneto, although as I said, part of my plan is to avoid smaller modules - especially if I plan to tweak them. I'm still not 100% on the Verbos Complex Oscillator. I can't really decide on that or the DPO or the Furtherrr Generator (or whatever it's called) without hearing them in person...
Thanks too, for what you say about my videos. I'm never sure whether the world needs more amateur videos about Eurorack, but it's nice to know that you enjoyed them. I haven't made one for a while (partly because of things going on) and also just laziness and my focus being aimed elsewhere at the moment. I do plan to make some more though - I have my Nifty Case patched up with a patch I like that I'm waiting to film...
