Dover Audio (website no longer available) has released a large number of plugins over the past year or so. They are done in SynthEdit and span all kinds of effects and synths.

A new one is B.D. Dover, a freeware basskick drum synth. This plugin is capable of some nice bass and club-type sounds as well.

If you’re familiar with Dover’s plugins, you’ll notice this plugin looks a little different than the average Dover Audio plugin.

Normally Dover’s plugins look like kind of plain SynthEdit-ish:

Dover Audio Daisypusher Extended v1.0

Thanks to Grymmjack, the B.D. Dover looks like this:

B.D. Dover

Now I’m not saying Dover’s GUIs are crap. Obviously it’s a matter of taste and they have their charm (just like many of Jack Dark’s plugins for instance).
And it’s true that whatever a plugin looks like doesn’t change it’s sound or performance, but it sure makes you think it is better. Seeing a nice GUI like the one on B.D. Dover does persuade me to download it and try it.

Anyway, check the free plugins on Dover Audio’s website for more free plugins. I’m sure you will find something useful.
