FrankenJazz vs Pulse16

Write a jazz progression, hear it immediately, and study what makes the changes connect. FrankenJazz is a private lead-sheet and harmony workshop for iPhone, iPad, and Mac. Enter chord symbols in a compact chart, choose a key and tempo, then play the form with a responsive chord-tone piano. The app reads Roman-numeral context, traces guide-tone movement, and lets you compare five practical voicing families. Use the bundled progression library as a starting point or build your own. Change the key, tempo, groove, instrument, and voicing while the chart remains editable. Playback includes seeking and looping for close listening and practice. When the chart is ready, export a FrankenJazz document, plain text, or a standard MIDI file. Local recovery protects the current session if the app closes unexpectedly. FrankenJazz works without an account or network connection. It includes no telemetry, advertising, sample downloads, or cloud processing.

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 • Six built-in grooves – Acid Drive, Peak Time, Neon Nights, Midnight Run, Kit Jam, French Filter: 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 • 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 AUTOMATION • Draw curves right over the pads of the synth track: cutoff, resonance, drive, distortion and reverb change from step to step • 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 (soft, hard, fuzz, overdrive) and a low-pass or high-pass filter on every sample track and kit pad 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 • 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 LIKE A PRODUCER • Volume and pan for every track, plus master volume • Sidechain pump on every track: the beat breathes with the kick, like French house • Boost: multiband compression on the master for a louder, denser mix, with low, mid and high • Reverb send for drums, samples and vocals; the synth has its own stereo reverb MADE FOR PHONE AND TABLET • On tablets, sound, mixer and presets stay open next to the pads • Low-latency audio engine No account, no ads, no tracking.
