one sound source - any of the VCOs
one modulation source - maths
one sound modifier - a filter
a way to play - either use the BSP you already have or get the es9 - up to you
a way to listen - quad vca

maybe add kinks to this

learn everything inside and out

add one module at a time - unless you realise you need more utilities to make it work properly - and repeat....

"some of the best base-level info to remember can be found in Jim's sigfile" @Lugia

Utility modules are the dull polish that makes the shiny modules actually shine!!!

sound sources < sound modifiers < modulation sources < utilities
