How Can Quantized Notes and Pitch Glitches Have Different Dynamics?

Separating Quantized Melodies and Pitch Glitches with Different Envelopes

Once quantized and non-quantized pitch streams exist, they do not need to share the same dynamic behaviour.

The chapter presents a technique that treats the two streams as separate musical entities.

Two Independent Signal Paths

The quantized melody is routed through a VCA controlled by an envelope.

The non-quantized pitch stream uses a different VCA path.

A Bernoulli gate determines which path becomes active.

The result is that scale-based notes and pitch glitches can possess entirely different dynamic characteristics.

Why This Matters

Listeners often perceive timbre and dynamics as strongly as pitch.

If both streams share the same articulation, the distinction between them may be subtle.

When they receive different shaping, the contrast becomes much clearer.

Musical Applications

The quantized melody might:

• use plucked envelopes,

• have a clear attack,

• occupy the foreground.

Meanwhile, pitch glitches might:

• appear without envelope shaping,

• emerge suddenly,

• function as interruptions or ornaments.

Creating Musical Roles

This technique effectively creates two performers within the same patch.

One performer follows tonal rules.

The other occasionally breaks them.

Conclusion

Separating quantized and non-quantized pitch paths through independent VCAs and envelopes creates a richer and more expressive musical result than simply switching between different pitches.
