Ritual Electronics Altar // State variable Eurorack filter with lots of CV control

Published on Feb 13, 2019 DivKidVideo

"**TIMING INDEX / SECTIONS BELOW** I was pleased to see Ritual Electronics announce Altar after first enjoying Miasma and working with them on that demo (link below). Altar is a state variable filter that rather than switching between low, band and high pass modes allows you to vary and blend between them both with the knob AND with CV control. That's a fairly unique feature as you rarely see CV controlled filter types/states on modules. There's also CV over cut off frequency and resonance all with attenuverters and a second cut off control with the 1v/oct input. Finally there's a nice asymmetrically clipping gain stage on the input to push things that bit harder for filter burn and a bit of saturation.
