Audio Object is a pocket-sized music instrument for iPhone. It looks and works like a small piece of hardware — a wooden body with an instrument panel on each face. Pull the wood edge and the body rotates to the next face. WHAT IT DOES - Four-track looper with bar-quantized recording and per-loop trim - Three-voice drum machine as the click track — kick, snare, hi-hat with a per-step accent grid - Eight-pad sampler with grid, auto, and tap chopping, two switchable banks, three-band EQ, varispeed tuning - Project save, load, and WAV stem export with tempo map - Streams audio to any Mac DAW over USB (Inter-Device Audio & MIDI) - Sends MIDI clock over USB — Ableton, Logic, and Bitwig lock transport to the phone - Records stereo from any Core Audio interface (iRig, Focusrite, MOTU, and others) HOW IT WORKS Six faces. Perform pads on one, sampler on another, click and time signature on a third, projects on the back, I/O on top, master on the bottom. No menus, no tabs. Every control lives on the body. The click track is not a metronome. It is a three-voice drum machine with per-step accents, subdivisions from quarter notes to swing, and time signatures from 3/4 to 12/8. Set up a kick-snare-hat pattern, press record, loop on the beat. The sampler holds eight pads across two banks. Record from the mic or load from Files. Chop by grid, by transient, or by tapping markers. Each pad carries a three-band EQ, varispeed pitch, and an amplitude envelope. All eight play polyphonically. Recording quantizes to the bar, the beat, or runs free. A dedicated loop-adjust face trims each loop to the sample — drag the region brackets, snap to the grid, hear the result while the brackets move. Plug the phone into a Mac over USB. Audio Object appears as an audio input and MIDI clock source. The DAW locks transport to the phone's tempo. No drivers, no setup. Plug a USB audio interface into the phone. Audio Object names the device on screen and records through its preamps at up to 48 kHz stereo. WHAT IS NEXT A synthesizer — bass, chord, and lead modes — is in development for the next major release.

SimpleSampler turns any sound into an instrument. Record a piano note, a clap, your voice or a glass you tap with a spoon. The app detects the pitch and puts the sound on a keyboard, so you can play it across several octaves right away. RECORDING Press record and the app shows you what it hears before the take starts. The recording begins with your first sound, not with the button press, so there is no silence or click at the start. If you don't like the take, cancel it and nothing is saved. KEYBOARD AND DRUM PADS The keyboard shows two octaves at a time and scrolls. It is fully multitouch, so chords and glissandos work. Eight drum pads hold eight different samples for beats. Pitch and length are independent: higher notes last as long as lower ones. If you prefer the classic tape sound, where higher also means faster, switch it on with one tap. LOOP STATION Tap a loop slot, play something and tap again to close the loop. Every new layer stays in time with the first one. You can also record a loop straight from the microphone. Your loops are still there the next time you open the app. RECORD YOUR SONG One button records everything you play: keyboard, pads and loops. It records what the app outputs, not what the microphone picks up, so the result is clean. Share it via AirDrop, Messages or any other app. PORTRAIT AND LANDSCAPE On iPhone, hold it upright to record and edit samples and turn it sideways to play. On iPad you get pads and keyboard on one screen. No account, no subscription, no tracking. Your recordings stay on your device unless you share them.
