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.

ScouterSynth is a music tracker built like a handheld console. Eight tracks, a D-pad, two buttons, and no menus — every operation is a chord you can play with your thumbs. WRITE Phrases of sixteen rows, chains of phrases, and a song made of chains. Write a bassline once and place it four times with different transposes; change it later and every one of those places changes with it. Phrases can be shorter than sixteen rows, so six-eight is as easy as four-four. SOUND A synth voice per track — saw, pulse with PWM, triangle and sine, through a resonant filter and an envelope — or a sample, played whole or sliced. Wavetables for the sounds a plain oscillator cannot make. Per-tick tables for automation that runs faster than a row. SAMPLE Import from anywhere on your phone, or record straight into a slot from the microphone. MP3, AAC, M4A, AIFF and WAV are all converted on the way in. Whatever you choose is copied into your project, so a saved song carries its audio with it. MIX Ten lanes on one screen — eight tracks and two send buses — with level, pan, mute and solo, and three effect slots on each: filter, bitcrush and a tempo-synced delay. Watch the desk as a set of numbers or as ten live traces. PLAY A performance pad wires any two parameters to an X and a Y axis and moves every track at once. A grid of twelve pads holds six punch-in effects — an octave down, tape slow, a stutter, a bitcrush, a high pass and a low pass — held rather than latched, so nothing can be left on by accident, and six one-shot samples to fire over the top. SEE A radar sweep that reads the mix by frequency, a scope on the output, and six palettes to put it all in. INTEGRATE MIDI in and out with clock. A Bluetooth game controller, mapped button by button to whatever pad you own. Export the whole arrangement to a WAV. Songs, samples and exports all sit in the Files app where you can reach them. No accounts. No subscriptions. No network. The manual is inside the app — press SELECT and B on any screen.
