Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
PaSSBot
This app is a stochastic filter bank audio processor for iPad, offering advanced sound manipulation with various filter types and powerful stochastic generators. It allows for precise control over filter parameters and harmonic distribution, ideal for creating complex audio textures.
- Stochastic filter bank audio processor
- Multiple filter types (Biquad, Ladder, SEM, Resonators)
- Up to 64 filters in stereo
- Powerful stochastic generators
- Individual filter parameter control
- Harmonic distribution options
- Precision DSP rendering (<1ms control rate)

PaSSBot is a unique stochastic filter bank audio processor. The desktop VST/AU version of PaSSbot has already arrived in February 2020 and this iOS version is equivalent to the latest version 2.1. PaSSBot filter types are Biquad, StateVariableFilter, Ladder, SEM and Resonators. With behaviors of bandpass, Lo + Hipass, Notch and up to 64 of them in true stereo ! The user can set values of center frequency, gain and resonance of the each filter, which will be then eloborated with powerful stochastic generators ( 4 independent GENs for each filter ) with continuous or discrete probabilistic distributions but also with standard waveforms. One can set each filter parameters individually, but also distribute them in harmonic order, again the harmonic spread ratio can be set by the user or even can be modulated by a GEN. Precision DSP rendering, less than 1milisec. control rate precision. The filters can run continuously or be triggered manually. In that case, each filter will be applied an independent AR envelope with configurable random duration. Important notes : - A recent iPAD model is being recommended and also setting the host buffer size to 128 or higher greatly helps to the CPU needs which also heavily depends on the number of parallel filters being used. - The resonators can be sensitive to input signal level. - The PaSSBot manual can be found at this link. https://www.sonic-lab.com/PaSSBot_files/PassBot_manual.pdf sonicLAB PaSSBot youtube playlist : https://www.youtube.com/playlist?list=PLP0cOkraQHDYUoMG6BETTN1eGm-Kq5z0T

Bungee turns your iPhone and iPad into a musical instrument. Touch the screen to play a granular synthesizer, pluck glowing stripes like strings, and let sequences and drum beats play along. No music theory needed: every note fits the scale, so everything you play sounds musical. Made for ambient music, beats, sound design and live jamming, from your first touch to a full performance. PLAY THE PLATE Every finger sprays clouds of tiny grains of sound. Move left and right to travel through the sound, up and down to change the grain size, press harder for denser clouds and swipe fast for stutter bursts. Up to ten fingers play at once. PLUCK, HOLD AND STRETCH STRIPES The stripes behave like strings. Pluck them, hold them to sustain, stretch them until they snap, or bow them with a slow swipe. Hold one stripe with up to four fingers and pull: the note rises as it stretches. Each stripe plays a note of the scale, and you can draw your own. THROW THE NODES Nodes sit on the stage and play whenever a stripe touches them. Drag them into place, or flick one and it flies across the stage like a bullet, bouncing off the edges and plucking every stripe it crosses. TEN LOOKS, ONE INSTRUMENT Pick a theme and the whole app changes with it, from the stage to the menus: - Chrome: liquid-metal strings and mirror-polished shapes (the default) - Clay: soft white clay on black - Neo Brutalism: bold colour, thick outlines, hard shadows - Acid: poster neon, holographic shapes and acid smileys - Pixel: 8-bit stripes and sprites, with a pixelated sound to match - Op Art: hairline stripes on a bending grid - Thermal: a heat camera where every pluck glows white-hot - Glacier: false-colour satellite maps - Orbit: planets gliding along luminous orbits - Bubble: liquid bubbles on cream Your home-screen icon can follow the theme too. 56 READY-TO-PLAY INSTRUMENTS Every template is a complete instrument with its own sound, stripes, effects and sequence, laid out on shelves: Techniques, Ambient, Melodic, Beats, Drums and Glitch. Long-press any template to preview it or star it. Or start a New project on an empty stage. LEARN IN NINE STEPS The guided tour shows each move on the stage, waits for you to try it and moves on: playing, swiping, the sequence, drawing stripes and working with nodes. DRUM MACHINES BUILT IN Ten drum templates play real beats: footwork, house, boom bap, bongos, metal, wood, chiptune, IDM clicks, water drums and half-time trap. Play along on the stripes. SOUND NODES AND SAMPLES Drop sample, synth, noise and drone nodes on the stage and play them by holding or dragging, each with its own volume. Choose from 13 built-in samples (kalimba, felt piano, Rhodes chords, tape choir, rain, birds, shortwave radio and more), or import your own audio from Files: WAV, MP3, M4A, AIFF, FLAC and OGG. SEQUENCER Pick a pattern and a tempo, or open Advanced for the step grid, Euclidean and Turing patterns, swing and direction. Sequences drive the notes, move nodes and animate the stage in time with the music. EFFECTS AND MIXER Shape your sound with reverb, delay, phaser and drive, and balance everything in a touch-friendly mixer. MIDI, AUV3 AND ABLETON LINK - Use Bungee as an AUv3 instrument inside your favourite host app - Connect a MIDI controller and it maps itself: Korg nanoKONTROL2, Novation Launch Control XL, Launchkey Mini and more, plus MIDI learn for anything else - Sync the tempo with other apps and devices over Ableton Link MAKE IT YOURS - Save projects and your own templates, and share them - A retro terminal view that shows every event as you play WHO IT'S FOR - Ambient, lo-fi and electronic musicians looking for new textures - Beatmakers who want a playful drum machine - Sound designers who want a hands-on granular synth - Beginners who want to make music without learning an instrument Everything is generated live on your device. No account, no sign-up, no subscription. Touch the screen and start playing.

Verdict
The clearest difference is price: Bungee at $9.99 against PaSSBot's $34.99. Bungee also leads on update cadence (every 5 days vs every 4 months). PaSSBot's advantage is iOS requirement (11.0 vs 16.0). On ads, in-app purchases and device support there is nothing between them.
