I think Maths is quite easy to understand actually at it's most basic it's just 2 function generators and a mixer - definitely worthwhile and even more so if you work your way through the illustrated manual a couple of times
never enough mixers or vcas!
sounds like a vc trigger/gate delay would be useful to add some swing!
try mixing and then sending through a reverb or delay - it'll help gel them together - maybe surface is best through filter first, though!

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
