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.
