Step sequencer & bass synth

Free · In‑App Purchases

Tap out a beat on 16 pads or play a kit live, add a sliding 808 or an acid synth line, switch eight patterns live and sync your gear via MIDI clock. Pulse16 is a beat maker and step sequencer for making beats anywhere: a drum machine with 16 pads, a deep 808 bass, a punchy synth and acid lines with 303-style slides. READY TO PLAY • Five built-in grooves – Acid Drive, Peak Time, Neon Nights, Midnight Run, Kit Jam: drums, bass line and tempo in one tap • Built-in techno and synthwave drum sounds (kick, clap, gated snare, hats, rim, tom) BUILD A BEAT IN SECONDS • Tap the 4x4 drum pads to switch steps on and off — the playing step lights up as the beat runs • Three drum tracks for samples, a kit, the 808 or a mono synth, plus one synth track • Velocity per step from 5 to 100 % for groove and dynamics • Set each track's length from 1 to 16 steps for polyrhythms • Tempo from 20 to 300 BPM, with tap tempo • Eight patterns A–H: switch live, right on the next bar; copy, paste and clear patterns, copy and shift single tracks • Duplicate a track: its steps repeat and the length doubles – build one beat, then vary it KIT MODE: 16 SOUNDS ON THE PADS • Turn any drum track into a kit: 16 sounds on the pads, like a groovebox • Play the pads live and record them into the pattern with Rec – in time, with erase and undo • Or set the steps of each sound by hand • Volume, pan, tune, distortion and choke groups per pad • The pads of your MIDI controller play and record the kit too, with their velocity 808 KICK AND BASS • Turn any drum track into an 808: a booming kick or a tuned bass line with a note per step • Shape it with decay, punch, click and drive • Slide per step: the 808 glides into the next note, like a classic acid bass line; the glide knob sets the slide time • Four 808 presets, from Classic Kick and Long 808 to Trap Slide and Distorted MONO SYNTH ON ANY TRACK • Turn any drum track into a second synth: the full synth with all its sounds, one note at a time • Slide per step: notes glide into each other like a TB-303; the glide knob sets the time • An acid bass line on one track, chords on the synth track AUTOMATION • Draw curves right over the pads of the synth track: cutoff, resonance, drive, distortion and reverb change from step to step • Glide smoothly from step to step or hold each value • Every pattern keeps its own curves YOUR OWN SOUNDS • Load WAV, AIFF, MP3 or FLAC files • Record your own samples with the microphone • Trim each sample right on its waveform and preview it instantly • Tune every sample up or down by two octaves, with fine tuning • Distortion on every sample track: soft, hard, fuzz or overdrive A BASS SYNTH WITH CHARACTER • Sine, square, saw and triangle waveforms • Low-pass and high-pass filter with resonance and envelope • Attack, decay, sustain and release • Distortion, drive, sub oscillator, unison and reverb • Four LFOs, free or synced to the tempo, one of them can sweep the filter • Set a note for every step with the built-in keyboard • Nine factory sounds, from Berlin Minimal and Acid 303 to the synthwave Outrun Bass • Arpeggiator: every note becomes an arpeggio – major, minor, sus4, 7th, power or octave chord, up, down, up-down or random, 1/8 to 1/32 triplets, over 1–3 octaves PLAY IT WITH HARDWARE • Connect a USB MIDI controller and assign its knobs, faders and pads with MIDI learn: synth, mixer, tempo, play/stop, tracks, patterns and steps • MIDI clock over USB: follow a drum machine or DAW, or send the clock and start your gear in time SAVE YOUR WORK (ONE-TIME PURCHASE) • Save and load whole projects: patterns, samples, sounds and mixer • Save your own synth and 808 presets • One purchase, no subscription; everything else is free MIX IT • Volume and pan for every track, plus master volume MADE FOR PHONE AND TABLET • Clean dark design built around the pads • On tablets, sound, mixer and presets stay open next to the pads • Low-latency audio engine No account, no ads, no tracking.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

New: velocity per step on every track and every kit pad – long-press a step and set it from 5 to 100 %. Duplicate repeats a track's steps and doubles its length: build one beat, then vary it. Arpeggiator on the synth track: chord, direction, rate up to 1/32 triplets, octaves and gate. A held synth note now stops once its step is deleted.
