Bitwig educator and Polymer specialist demonstrates wavetable synthesis as part of a broader synthesis walkthrough, focusing on how to load wavetables and use a ramp modulator to scan through wave shapes on each note. Unlike sampling, wavetables require loaded content to produce sound, but the library inside Polymer already contains a wide range of shapes, including importable formats.
The ramp modulator works like a simplified envelope: it moves from one value to another in a straight line, and here it drives the wavetable position so each note reads through the shape from start to finish. Adding a slight curve to the ramp softens the attack into something more chiff-like, and velocity can be mapped to the curve amount for extra expressiveness.
Looping the ramp modulator shifts the behavior from a one-shot scan into something more like a sequenced oscillation, giving each voice its own cycling movement through the wavetable. In a polyphonic context, this creates an evolving, self-generating quality that goes well beyond static waveform playback.
