Frequently Asked Questions
It smoothly transitions between lowpass, bandpass, and highpass filter types, subtly altering resonance and Q-factor along the way – it's not just a simple mode switch.
Yes, it functions as a sine wave oscillator, but its timbre is very basic and lacks shaping options; best suited for simple drones or sub-octave duties.
The Altar II has a more vintage, warmer tone, while Ripples is cleaner and more precise – it's a matter of preference, but the Altar II offers a distinct character at a more accessible price point.
