Manifold vs PaSSBot
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Manifold
This app acts as an intelligent MIDI controller for the Elektron Octatrack sampler. It offers advanced randomization, parameter control across all tracks, and specialized sound design functions. Real-time scrubbing, instant parameter recall via snapshots, and a chromatic keyboard are also included.
- Intelligent randomization, morphing, and resetting
- Control parameters across all tracks
- Sound design functions (fade, mixer, etc.)
- Modulation mode for animating parameters
- Real-time sample start and FX scrubbing
- Snapshot recall for parameter states
- Chromatic keyboard and transport controls

- 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
Verdict
The clearest difference is review sentiment: PaSSBot at 100% against Manifold's 33%. PaSSBot also leads on rating (5.0 vs 4.3) and iOS requirement (11.0 vs 13.0). Manifold's advantage is price ($12.99 vs $34.99). On ratings volume, update cadence, ads and in-app purchases there is nothing between them.
