Pitch vs Amplitude

Two knobs hidden in every sound.

Two knobs hide in every sound: how fast, and how big.

// WHAT IT DOES

Every wiggle has two basic measurements. How fast it repeats decides the pitch. How tall each wiggle is decides the loudness.

On a synth those are controlled in different places. The oscillator section chooses pitch. The amp section chooses loudness — usually with an so it can change over the life of a note.

They're independent. You can play a quiet high note or a loud low one; the synth treats those two properties separately.

Think of it like → Pitch is how fast you wave your hand; volume is how wide. Try waving fast and small, then slow and huge — same arm, two independent variables.
▸ WHY YOU CARE
  • It explains why turning up the volume doesn't change the pitch — they live in different parts of the signal chain.
  • It also explains why -to-volume sounds 'expressive' but -to-pitch sounds 'broken'.
  • When you mix, EQ deals with pitch content and faders deal with loudness — same .

// SEE & HEAR IT

▸ Two oscillators blend to one waveform. Detune fattens by making them slightly out of tune.

▸ HOW IT WORKS
▸ Signal flow — watch the dot

▸ LISTEN FOR
  • Pitch changes feel like the note is climbing or falling.
  • Loudness changes feel like the note is getting closer or further.
  • The two never bleed into each other on a sane preset.
▸ WALKTHROUGH (4 steps)
  1. 1. DO: Init the synth. Play and hold a C3.
    ▸ LISTEN: A steady tone at one pitch, one loudness.
  2. 2. DO: Slowly turn the oscillator pitch up an while held.
    ▸ LISTEN: Loudness doesn't change; only the perceived note moves.
  3. 3. DO: Return to C3. Slowly pull the amp level down.
    ▸ LISTEN: Pitch doesn't change; only loudness drops.
  4. 4. DO: Set velocity → amp. Play soft, then hard.
    ▸ LISTEN: Hard hits are louder, with the SAME pitch.
▸ COMMON MISTAKES
  • Confusing 'I made it brighter' with 'I made it louder' — brightness comes from filter/spectrum, not amp.
  • Routing velocity to pitch on a polyphonic patch (creates detune chords).
