Brainworx bx_cleansweep V2

The plugin in one sentence: 1x Lowpass-filter (Range: 20-22.000 Hz, 6 dB/Octave) and 1x Highpass-filter (Range: 20-11.000 Hz, 6 dB/Octave) which use brainworx' own "Anti-Cramp technology" and whose cut off frequencies can be controlled simultaneously by using the dedicated joystick.

I personally think the joystick component is a rather unuseful feature made much too prominent. Controlling both cutoffs for high-pass and low-pass filter can give you a solid band-pass filter, but the issue that the high-pass only ranges to 11k (although this is quite a great value for a high-pass on its own) limits the fun you can have with it.

The 6db/Octave butterworth filter indeed sound musical but one the other hand they are also very limited in the things you can do with them and allowing no surgical filtering. Not to mind about not having Resonance (Q) or gain parameters to shape the sound more to one's own needs.

I also do not like that each of the both filter actually has two separate control parameter, which again are very laid out far from each other on the desktop. You can use the little dials to the upper left side to swipe through the frequency spectrum and you also can do this via "mouse-over" controlling but these 2 dials neither give you information about the current cutoff frequency nor do they have the capability to type in the frequency.

This is what you do with the separate controls at the lower right, underneath the display. A kind of strange layout.

At last, I think that the name is misplaced. This plugin does not offer the accuracy to really provide clean and costumized sweeps as rather a raw but indeed very musical tool to create sweeps especially for the low-filter, since high-pass just cover half of the range.

The plugin could also have been updated to provide resizing, since it is small on modern desktops and values are hard to read.

Resume: For using it as simple low-and highpass-filter tool, it can be great, but even for that purpose it can give you a struggle because of its limited capacity and the way to use it.
