Voxengo OVC-128
In electronic music, many sounds are very much "upfront". OTT is what many choose for this purpose.
However, I have found that Varisaturator is much better in place of OTT when it comes to this purpose. Much more controllable and much smoother (even though OTT is multiband compression and Varisaturator is multiband saturation/inflation) In most cases where I would choose OTT, I am using Varisaturator instead for the same purpose and it does the job much better. This small change has improved my mixes for electronic music a lot.
Second thing is soft clipping with OVC-128 on buses to smooth and contain, then followed by high end expansion with Soniformer to rebuild some dynamics and transients is an amazing combination. Smooth, contained and dynamic.
Always finding new relationships and uses with your plugins, thanks!
