NOISE / EXT LEVEL
This knob is used to set the level of the White Noise Generator. Its value can 
also be controlled via the NOISE LEVEL CV input (VCA) on the Patchbay. 
An External Audio signal can be used in place of the White Noise Generator by 
connecting it to the EXT AUDIO input jack on the DFAM Patchbay. The level of 
the External Audio signal would then be attenuated using this knob. 
NOTE: The EXT AUDIO input jack is a 3.5mm TS input and will not work with a 
standard 1/8" TRS headphone-style cable. Because this is a unity gain input designed for Eurorack signal 
levels, an external audio source applied to this input should be 10V peak to peak. Signals lower than this 
(an MP3 player for instance) will need to be amplified prior to being input to the EXT AUDIO jack for 
proper volume performance levels.
VCO 2 LEVEL
Use this knob to set the level of Oscillator 2. 
NOTE: The Square Wave will be perceived as louder than the Triangle Wave. 
This is due to differences in harmonic content and is completely normal. 
VOLTAGE CONTROLLED FILTER (VCF)
Your Drummer From Another Mother features a Voltage Controlled Ladder Filter that can be used in 
either Low Pass or High Pass mode. The purpose of this Filter is to dynamically shape the timbre of a 
sound by selectively removing harmonic content above or below the Filter’s manually selected Cutoff 
Frequency.
VCF
This switch is used to determine whether the Filter is in Low Pass or 
High Pass mode. 
LP (LOW PASS)
In this mode, harmonic content above the Filter’s Cutoff Frequency is 
attenuated, allowing only lower frequencies to pass. This mode is ideal 
for sculpting thick, dark, or natural sounds. 
HP (HIGH PASS)
In this mode, harmonic content below the Filter’s Cutoff Frequency is attenuated, allowing only 
higher frequencies to pass. This mode is ideal for crafting bright, thin, or snappier sounds.
