This plugin is great for visualising your filter tweaks, and allows for much more hands-on control than envelopes, especially for live playing. It can be used ever so subtly, or it can transform your sound into a glitchy monster, largely dependent of how trigger-happy you are, and what you feed into it. In terms of support you wont find much better in the realm of freeware, as Tweakbench has his forum right here at KVR, and is quick to respond to questions or problems. What i appreciate most though, is how consistent his plugins are. Every one has a matching interface, responds as you'd expect, and apparantly tries to incorporate much the same controls, which only adds to ease-of-use. With the updated controls, editing the bars with your mouse is now much easier than it was before. Try as i might, i've not been able to make it crash, nor any Tweakbench plugin, for that matter. The only let-down (in my eyes, being a preset-monkey) is that it's lacking in presets. I'd like to call attention to TB's request for user-patches, as he acknowledges that there aren't enough.
