KBD Tracking
The filter cutoff frequency can also be keyboard-controlled. The KBD
Tracking knob lets you adjust how the cutoff follows the keyboard. At the
full Counter-clockwise position the keyboard CV will not affect the filter cut
at all. With lower filter settings you will hear the sound get darker and darker
as you play up the keyboard. To have the sound track with the notes you are playing
and have the filter cutoff remain even across the scale, set the knob in about the 12
o’clock position. With the knob in the 12 o’clock position, it will open the filter at the
same approximate amount as the keyboard goes in pitch. Turning the knob to the
far right will make the filter open much faster across the range of the keyboard.
Envelope
The envelope is normally triggered by the keyboard GATE signal. It can also be
triggered by other GATE sources such as the Sequencer or the rear panel’s external
GATE IN jack.
The required gate signal at the back panel is a standard 5V positive gate. This
means that most modern modular synthesizers will trigger it properly.
Envelope Amount
The ENV Amount control will vary the output signal from the envelope. This allows
you to attenuate it, so that you can control how much of the signal goes to the
destination. To route the Envelope to a control destination, use the Mod Matrix. Note
that this control does not affect the Filter’s Envelope Amount control as it is a
separate feed.
VCA switch
The VCA GATE/Env switch allows you to select two options for controlling the output
level of the MicroBrute. By selecting GATE, the VCA (Voltage control amplifier) will
simply open and close based on the input from the keyboard, sequence or external
gate source. You will not have any kind of change over time with the level of the
