Custom Waveforms

Available from firmware 1.2.0

The PGB-1 allows you to draw and edit custom single-cycle waveforms that can be used with various synth engines.

Accessing Custom Waveform Editor

  1. Press Menu

  2. Navigate right to Custom Waveform

  3. Press A to enter

Editor Options

Draw Your Own

Edit the waveform manually:

  • Use ← / → to move the cursor horizontally

  • Use ↑ / ↓ to adjust the waveform value at that point

  • Use the touch strip to set the value directly

  • Hold ← while moving the touch strip to draw continuously

Load Preset

Load from built-in waveform presets:

  1. Navigate to the Load option

  2. Use ↑ / ↓ to browse presets

  3. Press A to load

Available presets include various classic waveform shapes that serve as starting points for your designs.

Using Custom Waveforms

Custom waveforms are available in specific synth engines. Look for engines with “Custom Waveform” in the name:

Bass/Lead Engines

  • Custom Waveform Glide

  • Custom Waveform Phaser

  • Custom Waveform Pluck

  • Custom Waveform Echo

  • Custom Waveform PDR (Phase Distortion Resonance)

Kick Engines

  • Custom Waveform Kick

  • Custom Click Kick (custom waveform with click)

Chord Engines

  • Custom Waveform (4-voice polyphonic using custom waveform)

Live Editing

One powerful feature is the ability to edit the waveform while playback is running:

  1. Start a sequence with a track using a custom waveform engine

  2. Enter the Custom Waveform menu

  3. Draw or load new waveforms

  4. Changes take effect immediately

This enables real-time sound design during performance.

Waveform Storage

  • One custom waveform per project

  • The waveform is saved with the project

  • Different projects can have different custom waveforms

Basic Shapes

  • Sine-like: Smooth curves for soft, warm sounds

  • Square-like: Flat tops/bottoms for hollow, reedy sounds

  • Sawtooth-like: Diagonal slopes for bright, buzzy sounds

  • Triangle-like: Symmetrical slopes for smooth, flute-like sounds

Tips

  • Use the touch strip for quick, expressive drawing
