Morph

Morphing is the act of gradually transforming one sonic state into another rather than switching between them abruptly. The most familiar example is a wavetable oscillator, where moving the table position smoothly blends between the stored waveform snapshots, letting a single note sweep through many different timbres. Morphing appears elsewhere too: some synths let you crossfade between entire preset states or between filter and effect settings, and spectral synths can morph the harmonic content of a sound directly. Because it happens continuously, morphing is best driven by modulation — assign an LFO or envelope to the morph position and the timbre evolves on its own, which is why wavetable synths excel at the living, constantly shifting textures that static waveforms cannot produce.
