ModularGrid Rack

I'd replace the vca with a quadcascading one such as veils, if you can and the filter with something smaller - doepfer perhaps - and add a kinks - and possibly a disting if it will fit

utilities more important you already have 2 modulation sources - tides and maths

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