Store description excerpt
Most songs cycle through a small, fixed set of chords. Oyoroi Jam gives you buttons for exactly those chords, laid out as full-width pads you can hit without looking. No fretboard, no 88 keys, no chord shapes to memorize. JAM IN A KEY No song in mind? You don't need one. Pick a key and Oyoroi Jam lays out the eight chords it is built from, in the order a keyboard climbs and labelled by degree. You are playing in about five seconds with nothing to set up, and Save turns anything you like into a song you can keep, edit, and practice. HOW IT WORKS Add a song, pick the chords it uses, and you have an instrument for that song. Tap a pad for a clean chord. Swipe across it to strum: how far you swipe sets the note spread, how fast you swipe sets the attack, and which direction you swipe decides down-strum or up-strum. String Crossing, a third mode, sounds a chord one note at a time as your finger passes each one, so a slow drag arpeggiates and a fast one strums. Where you tap a pad sets how hard that chord lands, so one pad can whisper or shout. Hold a chord and lift to damp it, or tap and let it ring. Change chord while you are still holding one and the notes both chords share carry through instead of restriking. BRING YOUR OWN SONGS Paste a chord chart, open a .cho, .crd, or .pro file, or AirDrop one from your Mac. Oyoroi Jam reads the chords out of a ChordPro chart and turns them into pads, so a song you already have a chart for takes about ten seconds. Lyrics aren't imported: what you get is the chord palette, ready to play. PLAY • Six instruments, all sampled from a General MIDI soundfont: acoustic guitar, electric piano, synth pad, organ, bell, and bass (which plays roots and octaves rather than full triads) • Per-chord inversion control (root, first, second) when the default voicing sits wrong • Transpose from -6 to +6 semitones on the fly, each pad still showing its original chord, so you can match a singer without re-editing • Three acoustic spaces to play in: Studio Dry, Warm Hall, and Spacious Arena • A separate six-pad drum kit (kick, snare, hi-hats, clap, tom), sampled from a real kit and drawn to answer every hit • Record what you play and share the take to Messages, Voice Memos, or anywhere else you send files PRACTICE • Practice Mode works on any song. Set a tempo, time signature, and how many bars each chord lasts, and it walks you through in time, with a scrolling queue showing what comes next • Nudge the tempo up or down while you play, so you find the speed by feel • Build a real arrangement out of named sections (Verse, Chorus, Bridge) rather than looping one flat list, and duplicate a section when it repeats • Quarter-note, eighth-note, or syncopated click patterns, in four click sounds • Visual pulse and audible click toggle independently, so you can feel the beat, hear it, or both ORGANIZE • Setlists: ordered collections for a gig, with Prev and Next inside the player so you can move through a set • Sort a song's pad
