One note regarding Let’s Splosh, you can find out how the outputs would sound when fed with Triple Sloth because your Triple Sloth’s + and - outputs are difference-rectifiers, the same thing that Let’s Splosh is a bunch of. 
If you’re leaning towards grabbing another Triple Sloth, I recommend first checking out the rest of NLCs range. I am very fond of Hyperchaos Deluxe (8 smooth outputs, 2 switched, 2 gates) and it can be built real slow if you want and you can switch between two different rates or almost “sync” it to a quick gate. I also built a Signum Hyperchaos, which is a bit like Hyperchaos Deluxe without the two speeds.
Finally, I’ve also built a super extra slow Brain Custard (slower than the CV version) that is thoroughly lovely. Not that many outputs, but it really behaves in interesting ways. More “jumpy” and wobbly, but still slow if built that way. The Hypster’s up next, and I’ve heard great things about how controllable that one is—in case that’s your bag.
