UPISketch4 vs Phasetable

UPISketch is a composition tool that keeps the principle of “pitch versus time” of the classical score, extended in the continuous domain. It allows for freely drawing absolute pitch curves applied to existing sounds. It uses granular synthesis. It can be used to sketch musical ideas, try alternative scales (divisions of the octave), and more. It is inspired by the famous UPIC machine that was invented in 1977 by Iannis Xenakis and the CEMAMu engineers. Version 4 introduces significant changes: improved sound quality, sequence recording, and a magnetic grid feature.

Four oscillators. Your own wavetables. Import a WAV, shape it while it plays, then put every detail in motion with MPE. Phasetable is a precision wavetable instrument for immediate exploration and serious production. Start with 54 factory banks or bring in your own WAVs. Open the standalone app or load the AUv3 inside a compatible host, touch a key, and hear motion before you reach for a manual—then go as deep as the session demands. BUILD THE SOURCE • Four independent wavetable oscillators with frame scan, coarse and fine tuning, equal-power pan, phase control and individual filter routing • 12 phase-warp modes, including PWM, Sync, Formant, Quantize and FM Self • Up to four unison copies per oscillator, plus phase or ring cross-modulation • Automatic band-limiting keeps movement clean across pitch, unison, Warp Mode and Cross Mod MAKE IT MOVE • Four wavetable-shaped motion lanes, free-running or tempo-synced from 1/32 to 4 Bars • Lanes that run globally, retrigger per note, or start every note from a random phase • 12 modulation sources, 36 destinations and 328 valid modulation routes • Dedicated Amp and Filter envelopes plus two velocity-sensitive envelopes that can loop per voice—all four route through the matrix • Velocity, key tracking, pressure and timbre as playable modulation sources • Envelope following that can steer lane depth, rate or frame from the dynamics of a performance SCULPT THE SIGNAL • Eight ladder-filter responses with drive, resonance, key tracking and a dedicated envelope • Per-voice noise for breath, impact and texture • Dirt for wavefolding and harmonic excitation • Tape for wow, flutter, feedback and stereo instability • Tempo-aware Echo and a four-line Space reverb IMPORT, BUILD AND EXPORT YOUR OWN WAVETABLES Bring your own wavetables into Phasetable. Import common PCM and floating-point WAV files as single cycles or multi-frame banks. Compatible cycle metadata finds frame boundaries automatically; unmarked files can be treated as one cycle or sliced into 2,048-sample frames. Multichannel files are mixed to mono, and every cycle is precisely resampled. Draw freehand or by line while the sound plays. Normalize, center, invert, reverse, smooth or reduce seam discontinuities. Add, duplicate, delete and reorder frames with 64 levels of undo and redo. A bank can hold up to 256 frames at 2,048 samples each. Save imported or drawn banks with complete presets, synchronize them through iCloud Drive, and embed them in project state. Export standard 32-bit floating-point mono WAV files for exchange with other compatible tools. PERFORM AND PRODUCE • Poly, Mono and Legato modes with glide and adaptive polyphony up to 16 voices • MIDI 1.0, MIDI 2.0 and MPE with per-note bend, pressure and timbre • MIDI Learn, controller feedback, assignable CCs and reliable host automation • A responsive 25-key performance surface with octave, sustain, velocity and panic controls • Live displays for envelopes, filter response, lane phase and every effect • Standalone sample rate, buffer size and MIDI input selection, plus output device choice on Mac START FAST. FINISH YOUR WAY. Explore 54 factory banks across nine spectral families and 34 factory presets spanning essentials, basses, keys, plucks, leads, pads, sequences, textures and effects. Search by category. User banks and presets can synchronize through iCloud Drive. Host automation and project recall remain attached to the same controls across compatible versions. Project state carries the tables it uses, so the sound you designed is the sound the session recalls. An integrated guided tutorial and detailed manual make the same instrument approachable on day one and transparent under expert scrutiny. Phasetable is built for iPhone, iPad, Mac and Apple Vision Pro.
