Perc8 vs EchoSketch

Perc8 is a professional drum synthesizer and step sequencer designed for techno, acid, industrial, and experimental electronic music. Build anything from tight loops to complete arrangements with eight independent synthesizer voices, deep per-step control, flexible effects, and a dedicated master bus. SOUND DESIGN Choose from a broad collection of kick, snare, clap, cymbal, hat, percussion, noise, tonal, and synth engines. Five purpose-built FM engines cover FM Kick, Snare, Hat, Perc, and Tone. Digital Perc adds a 16 × 16 WAVE × SHAPE sound space for animated digital percussion. Start quickly with 40 curated factory voice presets, then reshape them through Perc8’s complete synthesis and processing architecture. Every voice provides eight expressive engine macros plus resonant filters, EQ, drive, amplitude shaping, dual LFOs, effects sends, and output routing. Optional Drive Match on each voice and the master bus helps you judge saturation character without added loudness dominating the comparison. SEQUENCING & ARRANGING Program beats with probability, trigger conditions, fills, retriggering, ties, variable pattern lengths, and up to 16 parameter locks per step. Arrange pattern entries into Blocks, set repeats and Fill behavior, mute voices independently per entry, and draw long-form parameter automation with multiple interpolation shapes across the chain. ADAPTIVE WORKSPACE Perc8 adapts its editor to the available space. Work quickly in the compact iPhone and AUv3 layouts, or use dedicated full-screen Pattern, Chain, FX, and Master workspaces on iPad. Controls remain direct and touch-focused across standalone and hosted use. EFFECTS & MIXING Process voices through a dub-style stereo delay, algorithmic reverb, and chorus/flanger modulation, all with sequencer automation. Mix all eight voices with level, pan, mute, solo, EQ, sends, and flexible bus routing. Finish the kit with stereo image controls, master EQ, drive, Drive Match, trim, and limiting. STANDALONE & AUV3 Use Perc8 as a standalone instrument or as an AUv3 plug-in in hosts such as AUM. Route voices to individual outputs, synchronize to host transport, automate parameters, control voices over MIDI, and save complete projects, kits, or individual voice presets.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
