Build a Lo-Fi Bell

A rounded Wavetable bell with two high triangle tones, a soft room, gentle panning and digital texture.

Follow the synthesis steps in order. Use the audio examples and device screenshots alongside the settings.

Step 01 / 4

Tune the three bell tones

Load Wavetable and apply the starting settings. Enable both main oscillators and Sub. Select Basics → Basic Shapes for each main oscillator, with Position 25%, the triangle region. Set both oscillator effect modes to None and keep both pans centered. Leave Filter 1 Off for this first step and Filter 2 Off throughout.

Control Oscillator 1 Oscillator 2
Wavetable Basic Shapes Basic Shapes
Position 25% 25%
Semitone +16 st +18 st
Detune +30 ct −15 ct
Gain −21 dB −24 dB
Effect mode None None

Set Sub Gain −6.0 dB, Sub Tone 12%, and Sub Octave −2. Set global Transpose +12 st. These settings belong together: the sub ends up one octave below the played note, while the two main oscillators sit more than two octaves above it. Their unequal intervals create the bell character.

Set global Volume −7.0 dB, Poly 5, Unison None and Glide 0 ms. Keep global Time at 0% and Global Mod Amount at 100%.

Use this amplitude envelope:

Amplitude control Value
Attack 1.00 ms
Decay 4.30 s
Sustain −38 dB
Release 350 ms
Attack slope 0%
Decay / Release slopes 50% / 50%
Loop mode None

The fast attack gives a clear strike. The curved decay lets the bell fade while the key remains held; the quiet sustain leaves a faint residual tone. Set the three active MIDI modulation connections to Velocity → Amp 50, Pitch Bend → Pitch +2 st, and Mod Wheel → Osc 1 Position 15. Keep other matrix connections at zero. The mod wheel moves oscillator 1 toward a brighter waveform.

Step 02 / 4

Round the sound with a low-pass filter

Enable Filter 1. Choose Lowpass, the 24 dB slope and PRD circuit. Set Frequency 1.65 kHz, Resonance 34%, and Drive 0.00 dB. Use Serial filter routing and keep Filter 2 Off. Leave filter modulation from envelopes, LFOs and note pitch at zero.

The filter rounds the triangle harmonics and emphasizes the region around the high bell tones. Its fixed cutoff makes higher notes softer as more of their spectrum moves above the cutoff.

Next: Surround the bell with a room →

Step 03 / 4

Surround the bell with a room

Add Reverb after Wavetable.

Reverb control Value
Predelay 8.00 ms
Size / Smoothing 80.00 / Fast
Decay 1.50 s
Stereo 100.00
Density High
Dry/Wet 44%
Input Lo Cut / Hi Cut Off / Off
Reflect / Diffuse level 0 dB / 0 dB
Early-reflection Spin On
Spin rate / Amount 0.30 Hz / 17.50
Early-reflection Shape 0.50
Diffusion High On, Shelf
High frequency / Gain 4.50 kHz / 0.70
Diffusion Low Off
Diffusion / Scale 60% / 40%
Chorus On
Chorus rate / Amount 0.02 Hz / 0.02
Freeze Off

The early reflections connect the bell to the room. The high-frequency damping softens the reverberation, and the short room decay leaves the instrument's longer envelope clear.

Next: Add stereo motion and digital texture →

Step 04 / 4

Add stereo motion and digital texture

Place Auto Pan-Tremolo after Reverb. Select Panning, Amount 22%, Sine, Time Mode Rate, and Frequency 1.00 Hz. Choose Stereo Mode Phase, with Phase 180° and Offset 0°. Set Shape, Attack Time and Dynamic Modulation to zero; leave Invert, Harmonic and Vintage Off.

The small panning amount moves the bell and its room together without spreading them across the entire stereo field.

Add Redux last. Set Sample Rate 16.0 kHz, Bit Depth 12, and Dry/Wet 40%. Keep Jitter 0%, Shape 0%, DC Shift Off, and both Pre-Filter and Post-Filter Off.

The lower sample rate introduces additional high-frequency tones, while bit reduction roughens the quieter part of the decay. The dry blend retains the rounded bell underneath.

Use a light touch for quieter bells, or higher velocity for a stronger strike. Hold notes to reveal the long decay and quiet sustain. Chords combine the low fundamentals with the closely spaced high partials. Up to five notes can sound at once. Raise the mod wheel to brighten the first high oscillator.
