Cymbal Choking
BFD allows you to choke cymbals either with a MIDI note
or, for compatibility with e-drum brains, with aftertouch
(polyphonic pressure) signals.
You cannot use MIDI Learn for choke notes: you will
need to set them manually in the same way as other key
assignments.
Choke notes are not like other Hit types: they do not
represent a sound. Instead, they are a way of stopping a
cymbal sound from decaying.
Choke with Aftertouch
Enable this option in order to make BFD respond to polyphonic pressure (aftertouch)
signals for choking cymbals. This method of cymbal choking is commonly implemented in
electronic drum brains such as those in V-Drum and D-Drum systems.
Please note that, during tests with D-Drum cymbal triggers, it was found that the D-Drum
brain sends out slowly decaying polyphonic pressure signals for a long period after
the initial choke was initiated. BFD is optimized as much as possible to ignore these
redundant signals, but it is worth bearing in mind if you encounter problems while choking
cymbals with the D-Drums.
Auditioning Hits
You can audition each Hit type at varying velocity by
clicking on its name in the Page 1 and Page 2 tabs.
Veloicity is varied from the left (velocity 0) to the
right (127) of the name label.
Unloading Hits
The checkbox next to each Hit type indicates that it is loaded in the current Kit. If you
choose to, you can unload any Hit by unchecking the box.
This is use ful for unloading fl ams and drags if you prefer to play/program these yourself,
for example, or if you do not need fully open or shank hihats (unless going for a very
splashy, ringy sound). Since a small portion of the initial attack of each Hit in every
Kit-Piece is stored in RAM, it can be a very good idea to unload any Hit types which are
not required.
It is important to note that any unload settings are saved at the BFD Program level: these
settings are not saved with the Hit Options presets.
If you play a note for a Hit type which has been unloaded (or if a playing Groove con tains
it) then the closest available Hit type in the Kit-Piece will be used.
