A full studio. On your phone.
BeatForge pairs an AI composer with a real production environment — pure on-device synthesis, a sampler, deep sequencing and lossless mastering. Here's everything inside.
Sound engine
17 instruments
Electric piano, organ, clav, bell, marimba, plucked guitar, synth strings, choir, warm pad, flute, brass, plucks, saw & supersaw leads, sub, reese and acid basses — generated locally.
Record or import
Sample through the mic or import audio. Multi-sample zones play the nearest root in tune, with velocity layers, per-zone loop, root and reverse.
4 melodic + 7 drum lanes
Bass, lead, second lead and pad voices over kick, snare, hat, clap, ride, tom and perc — each independently sequenced and mixed.
Sequencing
- Flexible grid — 8 to 64 steps, switch between 16ths, triplets and 32nds.
- Piano roll — scale-locked by default so every note sounds musical, or go fully chromatic.
- Per-note p-locks — set velocity, probability, ratchets (sub-step retriggers) and filter cutoff on a single note.
- Groove — swing, micro-timing and per-step accents for a human feel.
- AI composer — describe a vibe and the model drafts drums, bass and harmony in key, ready to edit.
Mixing & mastering
- Per-channel mixer — level, mute, solo and lock on every drum lane and voice.
- Per-role shaping — tone EQ tilt, sidechain duck depth and delay sends per part.
- Master bus — glue compression and a final limiter.
- Live LUFS meter — watch integrated loudness and peak in real time as you mix.
Arrangement & performance
- Song mode — chain sections into intros, drops and breakdowns, each with its own tempo.
- Perform mode — trigger, mute and switch sections live; the change lands cleanly on the bar.
- Set Builder — auto-order tracks by Camelot key and energy, beatmatch to one tempo and crossfade into a single mixed set.
- Discover — hear what others made and remix any track into your own studio.
Export
Lossless master
24-bit / 48 kHz stereo master, mastered to a target loudness.
Per-lane WAV

On-device by design
Synthesis runs entirely on your iPhone — no sample streaming, no account required to make music, and it keeps working with zero signal. The AI composer is the only part that uses the cloud; everything you create is rendered locally.
