Device Details


Overview

Name | Version: qerror quantization error synth and FX 1.0
Author: tomme
Device Type: Instrument
Description: Sounds born from quantization error
Quantization error = difference between original analog signal 🎤 and digital representation 💻 after quantization.
This creates noise/distortion ⚡, especially in low-bit-depth systems.

👉 qerror devices link pitch ↔ quantization error to shape timbres:
🎶 Low notes = coarse, buzzy error
🎵 High notes = finer, hiss-like error
🎹 Attacks/decays = bursts then thinning

🎹 qerror instrument
Sine wave 🌊 → copy reduced in bit depth 🪓 → subtracted from original ➖ → leaves only the quantization error ⚡ = synthesis output.

Parameters:
🔢 steps – number of divisions
📊 steps % – ADSR depth on steps
🔄 mode – 1 (round), 2 (round + normalize), 3 (truncate)
⏬ resampling + resampling %
🎚️ LPF frequency / %
🎧 wide
🌀 glide



🎛️ qerrorFX
Same principle, but applied to input sounds 🎤.

Parameters:
🔢 steps + steps %
🔄 mode (1,2,3)
⏬ resampling + %
🎚️ LPF frequency / %
Onset notes 🎶 trigger steps, resampling, and filter.
🌊 smooth → softer attack
🕰️ decay → longer tail
