Iāve never actually used Pip Slope, but the lack of ability to control the curvature (without self-patching through external attenuators) or use it as a slew are marks against it IMHO. Though if youāre not too picky about adjustable slew rate, Cold Mac can handle that part.
Iād be more inclined to go for the Joranalogue Contour 1 than Pip Slope, though.
Other options Iād consider for a small case would be Stages (+ Shades or similar), or Zadar. Though to be honest, I think Maths is a pretty good setup in terms of functionality per HP and cost.
