RAM buffer
This value, in sample frames, is the size of the portion of each sound held in RAM to enable low latency operation within BFD2
(to circumvent the inherent latency involved with hard disk seek times). The portion held in RAM plays while BFD2’s streaming
engine cues up the rest of the data from the hard disk.
A larger value gives the hard drive longer to deliver the data, but is more demanding on RAM. If the setting is too low for your
system, you are likely to suffer from dropouts and other audio artifacts.
This value determines the length of each sound played when the Preview RAM audio only option is enabled.
Settings of 4096, 8192, 16384, 32768 and 65536 samples are possible, selectable via a drop-down menu. A setting of 16384 or
32768 is fine for most systems, while very fast newer machines may be able to run at 4096 or 8192. You should try to use the low-
est setting possible on your system.
Stream buffer
The Stream buffer is the size, in sample frames, of the buffers of data being streamed into RAM from the hard disk for each voice.
Generally, hard drives are more efficient at reading fewer large chunks of data than many smaller chunks. However, a larger
Stream buffer uses more RAM, and may be inefficient if not all the data is used, such as when notes are choked.
Settings of 4096, 8192, 16384, 32768 and 65536 samples are possible, selectable via a drop-down menu. Settings of 8192,
16384 or 32768 are fine for most systems: you should try to use the lowest setting possible on your system. If you set a value that
is too low for your system to handle, you are likely to hear dropouts or other audio artifacts.
Max cache buffers
This setting represents the maximum number of disk streaming buffers cached in RAM. If the same velocity layer is triggered
repeatedly, it is possible to avoid reading from the disk by reusing the disk streaming buffers with the same data. This param-
eter determines how much of your RAM you want to set aside in the hope of acheiving such reuse. If you have even a moderate
amount of dynamics in the performance, or if you are using Humanize velocity or Anti-machinegun mode, you may find that not
much reuse occurs at all, and could possibly reduce this parameter a little.
You still need at least 1 cache buffer per voice!
Max voices
The Max voices setting dictates the maximum number of voices BFD2 can play simultaneously. If the voice limit is exceeded,
BFD2 implements an intelligent voice-stealing system, based on the oldest voice which is still playing.
The number of voices required for a performance can be larger than you think. For example, decaying cymbals and toms can
raise polyphony requirements quite considerably. 64 is a safe number to use, and voices don’t use much RAM.
Max velocity layers
You can limit the amount of velocity layers used by BFD2, thereby reducing the strain on the hard disk and RAM, at the expense
of detail. If a kit-piece is loaded that has more layers than the number specified with this setting, BFD2 only loads the selected
velocity layers at proportional intervals over the velocity range, so you still get the benefits of BFD2’s natural variations in kit-piece
timbre and dynamics, only with less ‘resolution’ over the velocity range.
Smaller values can be useful as an efficient preview mode while composing. Simply increase the value and restart the engine
before performing a final mixdown with full quality.
To change the setting, double-click the box and enter a new value between 1 and 256.
If you are using a low number of layers, it is recommended that you set the Vel to Amp default preference to a high positive value,
anything from +50% to +100%.
This means that all loaded loaded articulations are set to scale their amplitude over the velocity range, giving a smoother dynamic
range than a small number of velocity layers would allow.
Note that BFD2 allows further detail settings for each type of kit-piece, which operate as proportional reductions of the Max veloc-
ity layers setting. See the Detail preferences sub-section below for a guide to making these settings.
Synth options
Drummer perspective
Enabling this setting allows you to hear BFD2’s output from the drummer’s perspective, rather than that of a listener on the other
side of the kit. All pan settings are inverted, as are the ambience channels. The inversion occurs relative to the Flip ambience set-
tings for each kit-piece. This setting is enabled by default.
Disable SideStick tuning
With this preference enabled, the sidestick articulation for snares is not affected by changes to the tune and master tune param-
eters in the Kit page. This results in behaviour that more closely resembles how a real snare works.
