Motif
This selects a motif and applies it to the modulation oscillator. A motif is a decorative embellishment of a periodic waveform. It can emulate various types of gadrooning—specifically reeding and fluting—commonly seen in classical architecture and furniture design. The table below explains the available motifs.
| Motif | Appearance | Method | Expression |
|---|---|---|---|
| Reeds | Convex ridges | Negative values are made positive; full-wave rectification | abs(x) |
| Flutes | Concave grooves | Positive values are made negative; inverted full-wave rectification | −abs(x) |
| Parted Reeds | Convex ridges separated by gaps | Negative values are zeroed; half-wave rectification | max(x, 0) |
| Parted Flutes | Concave grooves separated by gaps | Positive values are zeroed; inverted half-wave rectification | min(x, 0) |
