Moog Music has a new video out today on The Moog Ladder Filter, the patent for which Bob Moog is being inducted into the National Inventors’ Hall of Fame.
Rick Shaich, Moog Hardware Engineer, narrates the video and explains the Ladder Filter’s important distinction of being “voltage controllable… It’s really the heart of subtractive synthesis, which is ‘The Moog Sound.'”
It’s a great explanation of what a Ladder Filter is/does, and the role it has played in modern music.
SineVibes had introduced Torsion, a new monophonic Audio Unit synthesizer that offers multiple synthesis technologies and modulation sources.
Torsion’s sound structure is similar to a traditional subtractive synthesizer – three oscillators going into a low-pass filter and into an amplifier. But Torsion’s oscillators are different: they produce simple additive waves based on just a few partials, which are then enriched with spectral content using a technique called waveshape modelling (which literally “curls” the wave in real time).
To further spice the sound up, there is a ring modulator and an audio-range oscillator for filter FM. Continue reading →
