MegaBass goes Titanium. The biggest, deepest MegaBass ever built — a complete drum machine, multitrack recorder, mixer, and arranger in one app. Make the beat, record over it, chop it, mix it, and arrange the whole song without ever leaving your device. Built for producers who go all the way in. QUAD DRUM MACHINE Program your pattern on a tight step sequencer, lock the groove, and build it out up to 64 bars. FULL MULTITRACK RECORDING Lay down up to 8 audio tracks right over your beat. Count-in (1-2-3-4), set your record length in bars, plug in your earbuds, and punch in clean. WAVE EDITOR Chop and trim every take with fine, precise control. Zoom the waveform out wide, drag the in/out handles, and dial it in tight. 8-TRACK MIXER Every audio track plus your drum kit — faders, pan, solo, mute, FX sends, and live LED meters on every channel. SCROLLING TIMELINE Drag your clips onto the bars, stretch the waves to see every detail, and scroll through all 8 tracks at once. TONAL KEYS — MONO / POLY Play melodies and basslines, then flip to MONO so your low end cuts clean with no overlap. ALL-NEW DARK LOOK Redesigned electro interface with the signature MegaBass war-dogs theme. REBUILT ENGINE A faster, smoother audio engine — locked tight, no freezes, no dropouts. Up to 64 bars • Live sequence mode • Song arrangement • One-shot mixdowns. Record. Chop. Mix. Arrange. All in one machine. This is the one.
