Perc8
Drum synth, sequencer, FX
$9.99 · Designed for iPad. Not verified for macOS.
Perc8 is a professional drum synthesizer and step sequencer designed for techno, acid, industrial, and experimental electronic music. Create everything from tight four-bar loops to complete arrangements using eight independent synthesizer voices. Each voice is a fully-featured drum instrument with its own engine, filters, effects sends, and modulation.
SOUND DESIGN
Design unique percussion sounds with multiple engine families including kicks, snares, claps, cymbals, hats, and noise percussion. Each engine offers eight expressive macros for intuitive, musical control. Shape tone with 7 filter types and multiple distortion algorithms. Process the entire drum kit with professional effects: delay, reverb, and chorus/flanger.
SEQUENCING & ARRANGING
Build sophisticated patterns with a step sequencer featuring probability-based triggers, conditional fills, per-step parameter locks (p-locks), and variable-length retriggering. Chain patterns into full songs with timeline-based automation. Modulate any parameter across your arrangement with the Chain editor.
STANDALONE & AUV3
Use Perc8 as a standalone app or as an Audio Unit plugin in your DAW. Route individual voices to separate outputs. Export patterns and kits. Create and organize presets: voice presets, full kits,
and complete projects.
