PLICATA is a compact patchable monophonic instrument for hands-on sound design and performance. A morphing oscillator feeds wavefolding, a resonant filter and flexible VCA contour, while an independent SUB oscillator adds octave, interval and eight waveform modes. PATCH IT The 28-socket patch system opens audio, CV and event routing. Modulate FOLD without replacing the oscillator path, reset the LFO externally, replace the internal SUB source, control SUB level by CV, distribute modulation through MULT, or build feedback and audio-rate networks. Patch cables are recalled with your sounds. MICROTONAL XY PERFORMANCE The 13-key XY keyboard spans C4–C5. Tune every key independently by ±100 cents or start from 12-TET, Just Intonation, Pythagorean and quarter-tone templates. Horizontal movement adds pitch expression up to ±24 semitones; vertical movement can map each key to as many as eight sound parameters or performance macros. PERFORMANCE VIEW + 32-STEP ARPEGGIATOR Tap PERF for an expanded keyboard-focused surface. The arpeggiator follows INTERNAL, HOST or MIDI clock and offers UP, DOWN, UP/DOWN, AS PLAYED, RANDOM, WALK, CONVERGE, DIVERGE and CHORD styles across up to four octaves. Build patterns from 1 to 32 steps with independent pitch, octave, velocity, gate, probability and ratchet lanes. HOLD captures the note pool; FILL creates a momentary variation. Adjust swing, gate, velocity behavior, probability and ratchets live. Rotate patterns, create temporary MUTATE variations, FREEZE the result, and recall seven ARP scenes with optional MIDI keyswitch control. MACROS, MIDI AND SYNC Six bounded performance macros shape tone, motion, fold, envelope, drive and level. IGNITE is editable: choose multiple targets, ranges and response curves, then store the mapping independently from sound presets. Play compatible instruments from PLICATA’s built-in keyboard using MIDI or MPE OUT, with independent pitch expression for each note in MPE mode. PLICATA also supports MIDI/MPE input, host sync and externally reset or free-running LFO operation. COMPLETE SOUND STATES PLICATA ships with 20 factory sounds and a full user-preset system. User sounds recall synthesis, patch cables and performance configuration together. Search, organize, favorite, duplicate and tag sounds, or use GEN to create a complete new musical state without overwriting your library. USER presets share the same library between standalone and AUv3. Optional private iCloud sync keeps them available across devices using the same Apple Account. Local presets remain available offline; sync requires network access and available iCloud storage. STANDALONE + AUv3 Use PLICATA standalone or as an AUv3 instrument inside compatible Apple music hosts. FEATURES • Morphing oscillator, wavefolding and pulse-width shaping • Independent SUB oscillator with interval and eight waveform modes • Resonant filter, ADSR articulation and drive • 28-socket audio, CV and event patch system • 13-key microtonal XY keyboard with independent tuning • Dedicated PERFORMANCE view with expanded keyboard • 32-step arpeggiator with nine styles and three clock modes • Per-step pitch, octave, velocity, gate, probability and ratchet • HOLD, FILL, rotate, MUTATE/FREEZE and seven ARP scenes • Six performance macros plus editable IGNITE • MIDI/MPE input and built-in keyboard MIDI/MPE output • Factory and user presets with complete-state recall • Complete-state generation with GEN • Standalone and AUv3 operation Explore PLICATA: https://trambustissimo.com/#plicata Support: support@alessandroguardascione.com

Verdict

The call

The clearest difference is price: User Scale at Free against PLICATA's $7.99. User Scale also leads on review sentiment (100% vs 67%) and iOS requirement (8.1 vs 17.0). PLICATA's advantage is rating (4.6 vs 3.5) and update cadence (every 3 days vs every 13 months). On ratings volume, ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PLICATA holds the better App Store score, 4.6 against 3.5. Both are backed by a comparable volume of ratings — 2 and 5 respectively. Written reviews complicate that: 100% of User Scale's written reviews are positive against 67% of PLICATA's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

User Scale ships an update every 13 months, PLICATA every 3 days. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
