Perc8 vs ARC

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.

Eight tracks. Synths, samplers, drums. Play it like an instrument. ARC-24 is a groovebox for iPhone and iPad. Pads, loops, and a mixer in one place. Everything stays in key. Pick a key and a scale and the pads follow, so you can play fast without landing on a wrong note. Record a loop, keep overdubbing while it runs, and fix whatever you fumbled on the grid afterwards. Once you've got a few loops going, chain them into a song. Or leave the transport running and fire them off by hand from the mixer. • Eight tracks that sort themselves out. Synth, sampler, or drums, decided by what you play first. Overdub while the loop cycles. • Note and chord pads locked to your key and scale. Hold latches notes so they sustain. Pulse retriggers them on the beat. • A sixteen pad sampler. Import WAV, AIFF, MP3, M4A, AAC, or FLAC, pull audio from a video, or record through the mic. Chop it into slices across the grid, or map one sample over every pad and play it pitched, in scale or chromatic, at the original length or at tape speed. • Ten drum kits, from 909 and trap to lo-fi, boom bap, and hand percussion. Tune, pan, and level every pad. • Synth editing that goes deep enough to matter. 21 presets to start from, two oscillators, filter, envelope, and LFO when you want to build your own. Save the keepers. • 25 arpeggiator patterns, all of them in your key, from slow drifting phrases to sixteenth note runs. • A piano roll editor. Move, stretch, and delete notes while the loop keeps playing. • A real mixer. Faders, pan, mute, solo, and three band EQ on every channel. • Every track gets its own effects rack, not a shared send. Resonant low and high pass with cutoff and resonance. Compressor and gate. Distortion, bit crusher, ring mod, flanger. Tempo synced delay in digital, analog, or tape. Reverb with chorus and tape wow. Character for texture, air, width, and warmth. • Motion, so synth parts never sit still. Slow LFOs drift the filter as the loop runs, and Bloom opens the cutoff every time you play a note. • Song mode. Arrange loops into sections, or switch between them live from the mixer without ever stopping. • MIDI in from a USB or Bluetooth controller. • Export to WAV or AAC. • iCloud. Start something on the iPad, pick it up on the phone. Seven days free, the whole app. After that one purchase unlocks it for good. No subscription, no renewal, nothing to cancel.
