0mA on +5V You will need 12HP of free space in your Eurorack case to install Altar. The module is 25mm deep. Connect the included ribbon cable to the module. Connect the other end of the cable to the bus board connector of your case.
It is particularly useful to recreate accent patterns à la 303. There is a gain at Altar’s input to beef up your signal which then distort the fi lter core. The fi lter tracks 1V/oct for 4-5 octaves and can turn into a very sweet sine oscillator.
Altar controls Frequency knob Sets the cutoff From sub-audio (≈2.5Hz anti clockwise) to ultrasonic (43.5kHz fully clockwise) Frequency attenuverter knob Going left the CV input is subtracted from the Frequency knob value. To the right the CV input is added.

Colors The Color act as a three input crossfader. It transitions smoothly from band-pass to low-pass to high-pass. This unusual BP-LP-HP fi lter arrangement is very suited for voltage controlled transition giving a more pleasant sweep than the usual LP-BP-HP.

1V/Oct Altar’s 1V/Oct input allows for fi lter tracking and sine oscillator functionality. It tracks over 4-5 octaves. You can adjust the tracking using the onboard vertical trimmer, located on the right side of the PCB. Calibration procedure You’ll need a way to measure frequency. The spectrum analyzer or tuner in your DAW can help you if you don’t have an oscilloscope or a multimeter.
New tones can be unlocked by patching the input or the output of the filter to its different CV inputs. As all our modules, Altar shines when self patched. Try patching its output in the Colour input to add thickness to the sound.
