qerror and qerrorFX - max for live

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
