Ohm Split pulls a finished song apart into vocals, drums, bass and the rest, right on your iPhone or iPad — for one payment instead of a monthly bill. BEFORE YOUR FIRST SPLIT Separation needs a one-time model download that shows its size first and a percentage as it arrives, and that you can cancel. After that, Ohm Split runs with no connection at all. A short sample track is built in, so you can try it before you touch your own music. SPLIT • 2-stem (vocals / instrumental) or 4-stem (vocals, drums, bass, other), with a real percentage while it works. LISTEN • Solo, mute and monitor any stem, set its level, and watch live meters. • Pick any subset of stems; an Original lane plays everything you left out. • Undo and redo mixer changes. EXPORT • Stems stay lossless WAV or FLAC. • Bounce the mix exactly as you hear it — mute the vocal for an instrumental, solo it for an acapella. • Share a stem or a bounce as AAC, or as MP3 where your device supports it. The lossless originals are never replaced. YOUR AUDIO STAYS PUT No account, no upload, no data collected. The only thing Ohm Split downloads is the separation model you approved. One purchase covers iPhone, iPad and Mac. Requires iOS 17 or later.

Ember is a full drive chain in one pedal — not another single-circuit distortion. A gritty, tweed-flavored overdrive sits on the bottom, a filthy fuzz runs layered on top, and compression is built in. It's the stacked-amps sound that normally takes three pedals and an afternoon of gain-staging, dialed in with one knob. THREE VOICES WARM — distortion the way it was first discovered: a pushed vintage amp with sliced speaker cones. Raw, retro, and touch-sensitive. Roll BITE up and it tips into blown-speaker sizzle with a starved-supply quiver in the note. DRIVE — everything, more. A doubled, dual-amp crunch straight out of the 1980s. The sustain sings, sizzles, crackles, and rings — and stays articulate. Chords keep their edges; every note in a run stays clear. RAVAGE — unhinged. The amps are on fire and the ship is going down. Stomp BOOST and single notes bloom into screaming, feedback-laced sustain that hangs on for the better part of a minute. Pinch harmonics, smoldering solos, sixties-fuzz recklessness at modern gain. WHAT IT'S FOR • Recording guitar direct — a finished, layered drive tone with no amp, no mics, no reamping. • Replacing a drive + fuzz + compressor stack, and the hour spent making them agree. • Leads that hold: BOOST adds gain, presence, and a sustain compressor that carries the note for you. • Practice anywhere — standalone app, plug in and play. CONTROLS THAT MATTER • DRIVE — one knob from edge-of-breakup to inferno. The molten orb burns hotter as you push it — and as you play harder. • TONE — dark and thick to bright and cutting, with a speaker-style rolloff that keeps fizz out. • BITE — round and smooth to sharp and shredded. • BIAS — starve it for choked, dying-battery textures. • IN / OUT / MIX for gain staging and parallel blends, stereo or mono, click-free bypass. ON STAGE AND IN THE STUDIO • AUv3 for GarageBand, Logic Pro, AUM, and any Audio Unit host. • MIDI learn on everything — knobs, voices, BOOST, bypass, even program-change recall of specific presets. A MIDI footswitch runs the whole pedal hands-free. • Factory presets plus custom presets. One purchase. Mac, iPad, and iPhone.
