Converting wavetables to Ableton Operator AMS waves

Posted on January 5, 2021 by bartwronski

This blog post comes with Ableton Operator AMS “wavetables” here. In Ableton’s FM synth you can use different types of oscillator waves as your operators (both carriers as well as modulators), as well as draw custom ones: What is not … Continue reading →

Checkerboard rendering, rotated anti-aliasing and grid frequencies

Posted on May 14, 2018 by bartwronski

This post is inspired by three interesting statements or questions that I heard and are interconnected by non-obvious theory: First was regarding so called checkerboard rendering (example1 example2) – what is advantage of using it? After all it’s the same as … Continue reading →
