Convergence (Free)

This is a pleasant sounding multiband compressor (xovers are set at 6db, which makes the response really smooth) with up to 4 bands, which is all you will probably need ever.

The interface is a bit quirky, because it does not allow you to set numbers by typing them, you have to turn the knobs.
It seems to have either a very soft knee, or some processing is always on, because as you play around with the crossovers before you even bring the threshold down, the sound changes.
As with all compressors the peak level of the signal will change (usually upwards) and there is no expansion setting, so you cant really use this plugin for mastering.

Apart from that, start with the default setting, bring the threshold down till you feel you are changing the tonal balance of the part, stop and add back level to each band to keep the compression control.

That is it. It is good and you can dial a great sound fast. I believe it works great on instruments, it is a bit too aggressive on buses.

This is a fully functional non expiring demo, so if you like it please support the developer.
