Pads. Warm, wide, ambient... it's interesting because while pads at their core are very very simple... it's often a real trick to get them "just right."
And actually, that is a subtlety many never quite get - a slight eq shift, a slight filter tweak, a subtle volume change - these can all dramatically impact the perception of pads.
(Well any patch I suppose - but with pads, the ability to really "sit" in a mix is key."
This collection includes an incredibly wide range of sounds - full, warm, bright, shiny... there's a lot of texture to utilize and experiment with.
Sounds from this bundle are literally on every single song I've worked on - over 1100 now.
I highly recommend checking them out, and messing with the subtle shifts possible in software. What you'll find is a deceptively large range of sound possible from just a few pads.
