Welcome
Thank you for downloading this fine plug-in from BetabugsAudio.
Thisplug-in fits right into our philosophy of doing an important
and powerfuljob, but in an elegant and easy to visualize way.
BugPass is a a dual-function plug-in. Its primary job is to
serve as a band-pass filter, with sliders which enable a quick
visual reference to the size ofthe frequency band being passed
through. However, by reversing the sliderpositions, BugPass will
also serve as a notch filter, eliminating frequenciesbetween the
sliders while leaving the remaining frequencies intact.
In order to get the most out of the BugPass, please spend a few
momentsreading this brief manual.

Controls
BugPass has two sliders for control. Depending on where they
arepositioned, the plug-in will act as either a band-pass or a
notch filter. Inthe following diagrams, note the positions of the
right and left sliders.In the Notch illustration, they are
reversed.
As a band-pass filter:
Only frequencies in the highlightedarea will be passed
through
As a notch filter:
Only the frequencies in highlighted areaswill be passed through.
In other words,
the frequencies between the sliders are cut.

Technical Information
BugPass is based on a 768 Tap FIR Filter-Kernel, which results
in aninitial delay of 768 samples, or 17.4 ms at 44100 Hz. This is
roughlyequal to the time it takes a soundwave to travel just under
6 metres.
The plug-in works at any sample rate, but remains mapped to a
range of 20to 22050 Hz. While there is never a loss in sound
quality when pushing asignal through BugPass, there is also no
benefit to using any sample ratehigher than 44100 Hz. In other
words, range and quality are independentof the sample rate.
Feedback / Bug Reports
We are always eager to hear feedback or have bugs reported. The
easiestway is to visit the Bughouse user forum, found at
BetabugsAudio.com. Ifyou would like to join us in future beta
tests, contact one of the team byBughouse private message for
