Available as a fully built module or a “finish-it-yourself” (with the surface mount parts pre-soldered). Both options come with the firmware pre-installed. You can swap our panel for another manufacturer’s panel!

Beads is a granular texture synthesizer that transforms incoming audio into shimmering atmospheres, fractured rhythms, pitch-shifted echoes, and evolving soundscapes. It captures sound in a recording buffer, then plays overlapping fragments called grains, with control over their timing, duration, pitch, playback direction, and envelope.
Reimagining the ideas behind Clouds, Beads combines improved audio quality and a longer recording buffer with flexible grain triggering and built-in randomization. From delicate variations to dense sonic transformations, its hands-on controls make it easy to explore the details hidden inside your sounds.
Each of the four main grain parameters has its own attenurandomizer. Use external CV to modulate a parameter or control its random variation, or leave the input unpatched to introduce internal randomness. Small adjustments add subtle movement; larger settings scatter grains across different positions, pitches, lengths, and shapes.
Four audio quality settings offer distinct characters, from clean digital processing to Clouds-inspired coloration and worn cassette textures. These settings shape more than resolution: they also influence saturation, limiting, reverb tone, and media-emulation effects.
Turn SIZE fully clockwise to explore delay and beat-slicing functions, including tap tempo, external clock synchronization, and pitch-shifted repeats. Leave both audio inputs unpatched and Beads becomes a granular wavetable synthesizer, using eight internal waveform banks. Separate feedback, dry/wet, and reverb controls put the final sound within easy reach.
Features
- Real-time granular processing with stereo input and output.
- Automatic input gain adjustment with manual override.
- Continuous, gated, and externally clocked grain generation.
- Forward and reverse grains with variable envelope shapes.
- Four attenurandomizers for grain modulation and randomization.
- FREEZE stops buffer recording; leaving it engaged for more than 10 seconds automatically saves the buffer contents for the next power-up.
- Delay, beat slicing, pitch shifting, and built-in reverb.
- Internal wavetable sound generation when both audio inputs are unpatched.
Controls
- TIME knob for position within the recording buffer.
- SIZE knob for grain duration and playback direction.
- PITCH knob for transposition, from -24 to +24 semitones.
- SHAPE knob for the grain envelope.
- DENSITY knob for grain rate or clock-related behavior.
- Four attenurandomizer knobs.
- Separate feedback, dry/wet, and reverb knobs.
- FREEZE and SEED buttons.
- Audio quality selector and CV assignment buttons.
Inputs and outputs
- Two audio inputs with automatic mono/stereo detection.
- FREEZE gate input.
- SEED trigger, gate, or clock input.
- DENSITY CV input, with 1V/octave grain-rate tracking.
- TIME, SIZE, SHAPE, and PITCH CV inputs.
- PITCH CV supports 1V/octave tracking with its attenurandomizer fully clockwise during external-audio processing.
- Assignable CV input for feedback, dry/wet, reverb, or combinations of these parameters.
- Stereo audio outputs; the left output sums both channels when the right is unpatched.
- Optional grain-trigger output using the right output jack.
