Here is the secret behind every great drum: the professionals build them in layers. A kick is a sub, a click, and a body. A snare is a tone, a crack, and a wash of noise. The traditional way means juggling samples, plugins, and routing to pull it off. Bruno makes that professional technique effortless.
Bruno is built around three ideas:
• Four synthesis engines per drum, layered in parallel, each with its own complete signal chain
• Six voice types that reconfigure all four engines for the right frequency range
• Intelligent randomization and a context-aware tweak system
The result is punchy kicks, cracking snares, shimmering metal, evolving percussion and twangy plucks.
Whether it is your first drum synth or your fortieth, Bruno meets you where you are. Hit the dice for an instant new sound. Roll a single engine or nudge one tab at a time. Or dive deep into per-engine sound design when you are ready.
SIX VOICE TYPES
• Kick, Snare, Hat, Clap, Tom, and Pluck
• Each voice retunes all four engines for its own frequency range and parameters
• Parameter values are preserved when you switch voices, so happy accidents carry across
• String-model Pluck with pickup comb, stiffness, and modal resonance
FOUR INDEPENDENT ENGINES
• Analog, FM, Fold, and Resonant, summed in parallel
• Every engine has its own tune, decay, and volume plus pitch envelopes
• Filters: 8 types with cutoff, resonance, bipolar envelope, and decay
• Three LFOs per engine: Cutoff, Pitch, and Character, with sync, gate, phase, and range
• Per-engine compressor, drive with 4 saturation types, delay with 4 types, and 3-band EQ
• Per-Engine noise, includes independently controlled noise decay, with white, pink and crackle noise.
• ON and OFF per engine, so a drum can be one engine or a dense four-layer stack
SHAPE THE TRANSIENT
• Dedicated Vol Env tab with click amount, click tone, decay curve, and tail
• Per-engine Body Peak EQ for tuned resonance and thump
• Voice-specific controls like Kick Tick, Snare BP wires, and Pluck stiffness and hum
MASTER FX BUS
• Saturator, Compressor, Transient Shaper, Reverb, Stereo width, and Limiter
• Global 3-band EQ with quick presets
• Copy to All across filter, compressor, delay, EQ, and every LFO
INTELLIGENT RANDOMIZATION
• Musical preset generator tuned per voice for usable drums, not noise
• Generate by style and target by category for each of the six voices
• Roll a whole preset, a single engine, or one tab at a time
• Tweak system for subtle, context-aware variations
• 100-entry history you can step forward and back through
• One-tap dice for instant inspiration
