Experimental MIDI sequencer/pattern generator designed for iPhones. // FEATURES - 3 tracks (A, B, C) - Triggers for each track (3 × 8 triggers) - Pitch values shared across tracks (row of 8 values) - Heptatonic scales quantizer (5 scale patterns × 7 modes × 12 roots) - Scale morphing using Triadic transformations - Degree mask per track (exclusion of specific degrees from the scale) - Degree shift (degree transposition) per track - Gate length per track - Track length control for Track A and Track B (with optional reset synced to Track C) - Track C Pause control (Track C will wait 0-8 steps before looping back to start) - Clock divider per track - Random step jump per track (probability) - Clock acceleration linked to B Track's playhead position - Swing and BPM clock control - Velocity and MIDI channel (1–3) per track - Velocity can be modulated by LFO (per track) with Rate and Amount control - Pattern evolution synced to Track C loop - Evolution has selectable groups of processes/transformations - Variations generator based on current pattern and evolution settings (16 x 4 variations) - Optional automatic capture of output to .MID files (synchronized to Play button) // EVOLUTION When evolution is triggered (Track C loop), it will randomly select one of the enabled transformation groups and apply one of the transformations contained in that group. Transformation groups can also be "locked-in" so they happen each time when evolution is triggered. List of available groups and transformations within them: PITCH - The order of pitch values is reversed - Two pitch values are swapped TRIGS - Two trigger states are swapped (within a single track) - Trigger patterns of two tracks are swapped - The trigger pattern of a single track is reversed SHIFT - The degree is shifted randomly on a single track MORPH - One of the 3 triads defining currently selected scale is rotated (replaced MODE transformation from previous version) PAUSE - Empty steps are added at the end of track C (0-8) FLIP - The pitch values of single track are inverted - The pitch values of all tracks are inverted STEPS - The track length of A or B track is randomized MASK - The degree mask is shifted horizontally by one step (left or right) BPM - BPM is halved or doubled - BPM is inverted (120 BPM taken as the axis) - BPM jumps to a random value READ 1ST - First variation on current variation page is loaded (this transformation is excluded from variation generation). ACCELERATE - Acceleration parameters is randomized (speed up of clock depending on Track B playhead position) RANDOM POSITION A - Random step parameter of Track A is randomized // PRESETS There are 5 × 24 available slots for user presets. BPM and scale settings can be ignored when loading a preset. Evolution variations (64) are saved within presets. // SAVING TO MIDI FILES Output can be automatically saved to a .MID type. File will be located at the “On My iPhone/sqsl Mantra” folder and named using the current date and time. Takes start when PLAY is activated and end/save when PLAY is deactivated. File saving can be enabled (“AUTO SAVE” setting on the MIDI page) even after playback has started, since note events are always automatically captured in memory. Important notes: - Mantra does not make any sounds on its own, it generates MIDI messages (notes). - Mantra is standalone application and it can not be loaded as AUv3 in other apps/hosts.

Ohms Sample turns any sound into a touch instrument and a generative loom. It is native on macOS and iPadOS, with all audio kept on your device. ONE PLAYABLE SURFACE * Orbit, Pulse steps, Mutation gestures, trigger pads, and a collapsible snapshot bank share one large instrument view; only Take opens a separate workspace. * Reweave sits beside transport and redraws the visible routes as it changes them. * Choose System, Light, or Dark appearance. PLAY AND EDIT * Slicer taps the waveform; Looper compresses a two-finger loop into grain; Tape scrubs speed and direction; Keyboard plays one slice chromatically. * Scroll and zoom the PCM-derived Sample Canvas from 1× to 8×. * Select a range, cut it or keep only it, reverse it, and apply pitch-preserving stretch from 50% to 200%. * Restore the untouched source at any time. * Detect and drag up to 16 transient-aware slices, with tune, volume, pan, attack, release, reverse, and loop per slice. WEAVE THE ORBIT * Draw weighted routes between the sample's circular slice arcs. * A seeded engine walks those weights while the live playhead makes every choice visible. * Run a 1–64 step Pulse lane, each step with its own openness. * Arm four weighted Mutation gestures per slice: stutter, reverse, speed, and scratch. * Morph across a 3×4 snapshot bank and punch in with four manual trigger pads. GRAIN AND EFFECTS * A preallocated native Swift engine renders up to 128 grain voices with position, size, density, pitch, jitter, reverse probability, and stereo spread. * Add resonant low-pass or high-pass filtering, feedback delay, and reverb. KEYBOARD AND MIDI * On Mac, A–P play the sixteen pads unless Sample Brain search is explicitly focused. * Generic MIDI controllers can use notes 36–51 or 60–75 for pads and 52–55 for triggers. * Learn CCs for grain, FX, and morph controls; receive and send MIDI clock; use virtual ports; and echo Orbit decisions as notes. LAUNCHPAD HARDWARE * Launchpad Mini MK3, X, and Pro MK3 get sixteen large 2×2 color blocks on Pads, plus focused Weave, Pulse, and Memory pages. * The on-screen mirror and hardware LEDs use the same direct visual language. CAPTURE SAFELY AND SEARCH LOCALLY * File and folder controls open system pickers. Sample Brain indexes any number of chosen folders for local search. * Microphone capture is armed only in Take. Finished audio stays staged beside the loaded sample until you choose Use Recording or Keep Current. * On macOS, Sample Anything can freeze the last 60 seconds of system audio from an in-memory buffer — audio only, never screen frames — with the same staged decision. EXPORT, SESSIONS, AND AUv3 * Export the edited audio as WAV, or save sample, slices, weave, mutations, snapshots, FX, and grain as a session. * The full generative engine and insert FX run sample-accurately in a macOS and iPadOS AUv3 instrument with 23 automatable parameters and host-saved state. Each instance keeps its own sample and can follow host tempo. * The AUv3 requests no microphone, file, screen-capture, or network access. PRIVATE BY CONSTRUCTION * No account, analytics, telemetry, advertising, cloud, or network calls. * No subscription or in-app purchase. $29.99 once for macOS and iPadOS as a universal purchase. REQUIREMENTS * macOS 14 or later, or iPadOS 17 or later. Sample Anything is macOS-only; microphone recording works on both.
