MNTRP is a drone instrument shaped like a journey: Earth to the Moon and back. A spaceship travels a figure-8 trajectory across the screen, and where the ship stands on that path IS the sound. There are no patches to browse — you play a position in space. THE TRIP The voyage passes through five stages, each with its own synthesis engines: • Liftoff — deep roaring engines, shaking metal • Interstellar — adventurous, airy drift (crossed twice: outbound and homebound) • Around the Moon — dark, mysterious, bowed strings • Reentry — the burn of coming home As the ship moves, the stages blend continuously into each other — a morph, never a switch. FLYING • Drag the spaceship along the path, or move the mission slider. • Or set a flight time (10–300 seconds) and press FLY: the ship flies itself and the sound travels with it. Missions loop — the entered time is one lap. Single-run mode lives in OPT. • The ship's position sets WHERE you are; the keyboard sets what sounds there. Nothing plays until you play. HOLD latches keys for hands-free drones. THE FIVE SHIP SYSTEMS The five big knobs mix the ship's systems, and each system keeps the same role through every stage: • ENGINES — the low floor: rumble, pedal, buffet • HULL — the ship's pitched voice • LSS — life support: the air • NAV — events and markers • COMMS — radio artefacts and telemetry TUNE Twelve shaping knobs under the TUNE panel: CUTOFF, RESO, DRIVE, TILT, TONE, SUB, ATTACK, RELEASE, GLIDE, RATE, DEPTH, SPACE. TRIPS — KNOB AUTOMATION Hold a still finger on any knob for two seconds to lock its value at the ship's current position — a red dot marks it on the knob's arc. Lock two or more points and the knob glides between them as the ship flies, around the full loop with no jump at the wrap. Name your trips, save them, load them. POV Press POV to ride in the cockpit: the Moon approach, the dark far side, Earthrise, the sun with its waving corona. Tilt your device to look around — the scene is a real 3D space in low-res pixel art: parallax stars, orbiting satellites, meteors, a photographed Milky Way. The sunlight follows your tilt, the terminator creeps across Earth and Moon — and at the right angle you can pull the Earth's shadow onto the Moon for an eclipse. AUV3 MNTRP ships as an AUv3 instrument and an AUv3 effect for hosts like AUM, GarageBand and Logic. The instrument is the full trip; the effect flies your own audio through the engines — the host signal bows the Moon's strings and feeds the reentry burn. Full state saving in the host; hardware MIDI in the standalone app. No accounts, no network, no data collected. Just the trip.

Make noise, texture, and percussion sing. Add motion and stereo spread to basic sounds. Load samples and sculpt them endlessly. Leave your mark on any sound with harmonic filtering. Sightlines is a playable harmonic filter. Built from a collection of resonant bandpass filters tuned to the harmonic series, designed to bring out a customizable set of musical frequencies in any sound. Tune it to a fixed frequency like a resonator, or send it MIDI to make it come alive as an instrument. Sightlines can be loaded as an instrument or an audio effect. As an instrument, use it with samples, noise, or oscillators to construct sounds never heard before. As an effect, add movement and interest to any sound, and even impart tonality onto unpitched input. SOUND SOURCES • Noise – filter variable color noise and random noise bursts for Sightlines’ simplest and quickest output. • Samples – send samples through resonant filters as one-shots or infinite looping versions of themselves, great for found sound and tonal samples alike. • Synth – skip the filters entirely and use Sightlines as a harmonic synth, where you can customize and modulate the proportion of each harmonic in the signal. • Audio effect – use Sightlines as an audio effect on any track. MOVEMENT AND EFFECTS • Manipulate overtones – stretch, bend, and reimagine the harmonic series to retune Sightlines’ output into realistic or indescribable sonic spaces. • Quantize frequencies – snap all of Sightlines’ filters to a scale, to impart that key quality onto any sound. • Balance bands – maneuver through the harmonic space by scanning, tilting, or spreading Sightlines’ bands. • End of chain – make your output shine with a built-in chorus, BBD-style delay, and reverb. FEATURES • Modulation – modify any control in Sightlines with multiple LFOs, sequencers, smooth random sources, and performance effects. • Presets – full preset control over every parameter in Sightlines. Cross-platform preset format for sharing with friends. • Waymaker – connect to Sightlines’ sibling application, Waymaker, for direct sequencing of Sightlines’ without MIDI routing. Also available for macOS and Windows in VST3 / AU / AAX formats from Aqeel Aadam Sound.

MNTRP's advantage is price ($6.99 vs $7.99). On rating, review sentiment, ads and in-app purchases there is nothing between them.
