Xfer OTT is an awesome tool for getting any instrument/loop more modern.
OTT is a 3-band compressor that works both upwards and downwards (that is, pulls quite sound up and pushes loud down). It was born out of somewhat famous Ableton compressor preset, but here you can finetune your effect to get just the thing you want. It can be barely visible, but people mainly use it to really pronounce something. Put a low-passed synth with some kind of subtle hi-freqs details in it ... and be blown away by what exactly multiband processing can get you this fast — and yes, for free.
Downsides: - latency of 2 samples (so no parallel processing without extra gimmicks employed) - somewhat noticeable CPU hit.
In other regards and if cooked right, it's simply awesome. Besides getting a job done, it's an extreme fun: feed rather detailed, high-quality, but not "pushed" source to it and watch it transform drastically, in a good way.
A great sculpting utility that can become a to-go tool for modern music producers. Absolutely recommended.
