Overview
Altar is a modern voltage controlled 3-pole, 18dB/
octave state variable fi lter.
The confi guration of the fi lter can be smoothly crossfaded
from BP to LP to HP. This unusual fi lter type arrangement
brings out very nice harmonics and nuances. It is really
suited for CV control.
Resonance is under voltage control with attenuverter as
well allowing for great timbre modulations. 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 is a completely original fi lter design by Mathieu
Fröhlich (creator of Squarp’s Hermod).
