Animate level LEDs

Enables animation of the level LED strips beneath the Mixer faders

Animate hihat position

Enables vector animation of the hihat position in the drum room window (especially
useful when operating hihat controller on an e-drum brain).

Enable context Info

This enables the context Info display at the bottom of the plugin interface. When you
move the mouse over a control or adjust it, the display shows a readout of the control
name and its value. You can turn off this functionality here if you don’t need it or fi nd it a
distraction.

-2 octave numbering

Some sequencers, such as Cubase and Logic, use an octave numbering system
which begins at C-2, rather than C0 in sequencers such as Sonar and FL Studio.
When it launches, BFD attempts to detect the sequencer used and adjusts the naming
convention used in the Hit Options panel and Groove Librarian Banks. You can override
this by manually setting this option in order to use whichever conven tion you prefer.

Choke Fade options

A Choke Fade occurs if a Hit is triggered before an older Hit from the same Kit-Piece has
fi nished decaying. For example, if you play 2 high toms rapidly in succession, the fi rst will
be faded out while the second is triggered.

The Choke Fade options allow you to adjust the fade times for the Kit. The default
settings apply to all Kit-Piece slots except for the hihat, tom and cymbal slots, which
possess their own sets of values. Different Kit-Piece types require different Choke Fade
times to sound realistic. Whilst short fade times for snares and kicks will sound fi ne,
cymbals will need much longer fade times, for example. Underneath the settings is a
Reset button, which causes all Choke Fade settings to revert to factory defaults.

There are two components to the Choke Fade time for each of the above categories:
fade (base) is the minimum fade time, while fade (range) is a maximum of extra fade
time added to the (base) value, according to BFD’s ‘dominant excitation preservation’
algorithm. The aim of this algorithm is to try to allow louder Hits (higher velocity) longer
fade times when choked by softer Hits (lower velocity), and to reduce the fade time when
a softer Hit is choked by a following louder Hit.

For example, a soft Hit choked by a loud Hit will have a fade time of fade (base), whereas
a loud Hit choked by a soft Hit will have a fade time of fade (base) + fade (range). This
leads to more realistic ringing when a cymbal is repeatedly struck, whilst reducing the
disk streaming load when possible.

You may want to reduce the hihat fade (base) and (range) times to very small values if
you want a really tight, cutting choke of open hats when pedalling or triggering a closed
hat.
