Deconpose splits any song into individual instrument tracks — vocals, drums, bass, guitar, piano — directly on your device. No uploads, no account, and the separation needs no internet.

MS-12 is a 16-pad sampler and step sequencer built around the sound of classic 12-bit hardware. Sample anything through the microphone, trim it, and play it straight from the pads. The sample rate and bit depth engine gives you the gritty, saturated character early digital samplers were loved for — not a filter placed on top, but the sound of the conversion itself. SAMPLING • Record from the built-in mic, a USB or Lightning interface, or line input • Resample the app's own output to bounce layers down • Threshold recording starts the moment sound arrives • Stereo or mono (L/R) capture SOUND • Adjustable sample rate (8–44.1 kHz) and bit depth (4–32 bit) • Presets for classic 12-bit voicings • Ring modulator, compressor, punch and saturation per pad EDITING • Trim, fade in and out, normalize, reverse, gain, silence • Time stretch • Auto slice by transient detection, or set slice points live with the pads • Split a stereo sample into separate mono left and right samples SEQUENCER • Step sequencer with velocity and tune per step • Real-time recording with selectable quantize • Up to 4 bars per pattern • Note Repeat • Song Mode chains patterns into a full track PLAYBACK AND MIXING • Volume and pan per pad, mute and solo • Mute groups so pads cut each other off, like a real drum machine • Pad Link to trigger several pads at once • Multi Level and Multi Pitch to spread one sample across the grid • 13 effects: tape echo, delay, reverb, chorus, flanger, phaser, tremolo/pan, distortion, overdrive, fuzz, wah, isolator and a 4-band EQ EXPORT • Bounce a pattern to a WAV file • Save projects on the device and reopen them later FREE VERSION MS-12 is free to try, and the sound engine is not held back — nothing about the audio is degraded in the free version. You get Bank A (16 pads), one 1-bar pattern, two effects, and microphone sampling up to 10 seconds per pad. A single one-time purchase unlocks everything: all four banks (64 pads), unlimited patterns up to 4 bars, Song Mode, all 13 effects, unlimited sampling time, loading your own audio files, project save and load, and WAV export. Anything you made before buying carries straight over. No subscription. No ads. No account required.
