What it does

Built for playing live, not for looking at.

LIBRARY

Nineteen sampled instruments

Concert, salon and studio grands, uprights, reed and string electric pianos, three historical harpsichords, chamber strings, solo violin, harp. Up to eight velocity layers, with string resonance, hammer and pedal noise — the detail that makes a piano sound alive.

SYNTHESIS

Three engines, not three presets

Subtractive with alias-free oscillators, a state-variable filter with drive, unison and analogue drift. Four-operator FM with eight algorithms. Additive with 32 partials, inharmonicity and spectral evolution. Every parameter is editable.

PERFORMANCE

Four slots, split and layer

Drag zones across an 88-key keyboard to build splits and layers, with velocity range, transpose and MIDI channel per slot. Each slot carries its own arpeggiator.

EFFECTS

A full chain, per slot and global

Interactive high-pass and low-pass filters, chorus, tempo-synced delay with ping-pong, five reverb algorithms — room, hall, cathedral, plate and spring — with per-slot sends, and a lookahead limiter that keeps a ten-note chord clean.

SAMPLER

Your own recordings, playable

Import audio from Files, let the app find the root note, set the loop on the waveform and map it across the keyboard. You hear it while you edit: what you hear is what you get.

RECORDER

Sample your own piano

Note by note, with the app guiding you. It detects each take, waits for the tail to die away and moves on. When you finish it tells you what your piano is tuned to, stretch curve included, and lets you keep that character or correct it.

On stage

It behaves like hardware.

A purpose-built C++ audio engine with low latency and 128 voices under CPU protection. Live meters, memory warnings, and a screen that will not sleep while you play. CoreMIDI over cable and Bluetooth MIDI, universal MIDI Learn on any parameter, maps saved per preset, tempo from incoming clock and preset changes over Program Change.
