ModularGrid Rack

needs more modulation sources & utilities...

modulation sources because they are what create movement

utilities because they create opportunities for patching...

take a look at my signature, especially the formula and see how you can apply that to your rack... it will exponentially improve it...

I'd add at the very least a quad lfo, a simple matrix mixer (for combining modulation sources), an attenuverter/attenuator/offset module and a quad cascading vca and probably a function generator or envelope generator (with at least 2 channels - so something like maths or zadar)

these will stop your drones being static and boring

there's a very good chance that you won't need the compressor...

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

sound sources < sound modifiers < modulation sources < utilities
