GSDSP MagicFusion vs TATAT
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
GSDSP MagicFusion
This advanced audio effect plugin offers precise spectral fusion and multi-curve vocoding. It allows users to extract spectral characteristics from one audio source and apply them to another, enabling detailed transformations from subtle shading to extreme effects.
- Multi-curve spectral vocoding
- Frequency-domain processing
- Independent fusion amounts per frequency
- Dynamic response control
- Formant shifting
- AUv3 audio effect plugin

The world’s first frequency-domain vocoder with multi-curve control and precision spectral fusion. Multi-Curve Spectral Vocoding MagicFusion is a multi-curve spectral vocoder workstation operating entirely in the frequency domain. Instead of relying on bandpass filters and envelope followers, it extracts the spectral characteristics of a modulator and applies them to a carrier, enabling precise, customizable vocoding across the entire spectrum. Apply independent fusion amounts per frequency or frequency range, then mix, modulate, and spread them to create anything from subtle vocal shading to extreme spectral transformations. Vocoder Signal Flow MagicFusion requires two audio inputs: the carrier (main input) and the modulator (sidechain). The plugin extracts the modulator’s spectral envelope and applies it to the carrier, creating a fused signal where both sources interact. This process provides clean, flexible control over the degree of spectral fusion and allows highly detailed shaping across the frequency spectrum. Dynamic Response & Formants Adjust the Smooth control to define how quickly the vocoder reacts, from fast, precise transitions to slower, more rounded movement. The Formant parameter shifts the spectral character of the modulator, while Detail adjusts the complexity of the filter response — from clean, intricate results to more organic, pumping behavior. MagicFusion is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).

TATAT is a MIDI FX designed to create always-changing sequences, to quickly sketch music ideas, to add unexpected events to fixed patterns. If you’re looking for new ways of generating musical ideas, then look no further than TATAT! Set up your parameters, define a mood and listen to an endless flow of notes which you can then record, tweak, and play along to. HOW IT WORKS /// TATAT generates infinite and always changing sequences of notes. You cannot say exactly what TATAT will do, but you can suggest a path to it: by setting up its parameters you can create what we call a mood for TATAT. A mood is a configuration of notes, intervals, time fragmentation, velocity fluctuation, and other factors. Once you set a mood that you are happy with, you’ll listen to an infinite stream of events, always changing, all staying in the mood. At this point, according to your needs, you can: - Let TATAT play its stream, and make some intervention to control it: to add silence (Less), to obtain smooth accelerando and ritardando (Ratio), to control how TATAT generates intervals. You can enable Key In function to change notes on the fly. - Add some stability by controlling/automating the Liv/Mem slider, moving between the generated stream and frozen patterns. - Use TATAT to send its notes to enrich (by enabling Thru) existing/incoming MIDI data/parts. TATAT gives you excellent results both with melodic/harmonic and percussive parts! MULTIPLE TIME RES /// Set chance for each time resolution to rule the stream, and scale results with main ratio to create organic time fluctuations. NOTES /// Set chance for each notes to get triggered, enable the keys toggle to change the notes on the fly, giving a different color to the stream. DOUBLE HIT /// Set two intervals and the probability they got triggered, adding harmonic weight to the stream. LET’S PROCESS THE STREAM! /// You can process the generated notes with several parameters: add a velocity variation, a delay, set the length, randomize, and mute some notes. It’s easy and intuitive. FLOW VS PATTERN /// LIV/MEM parameter has a 0-100% range. When is set on 0%, a buffer with given length continuously records the stream; when it’s different than 0%, the buffer got locked, and you set the chance to get live or buffered notes. When you set 100% you always have the buffer content as a static pattern. You add the stability you want to the lunatic stream! 2 FLAVOURS: DARK AND LIGHT SKIN *** Please note: TATAT is an Audio Unit extension (AUv3) – it only works in an AUv3 host app compatible with MIDI FX like AUM, Logic Pro, Cubasis, etc... ***

Verdict
The clearest difference is price: TATAT at $3.99 against GSDSP MagicFusion's $29.99. TATAT also leads on chart position (#185 vs unranked) and ratings volume (22 vs 4). GSDSP MagicFusion's advantage is update cadence (every 6 weeks vs every 19 months) and review sentiment (100% vs 90%). On rating, ads, in-app purchases and monetization model there is nothing between them.

GSDSP MagicFusion costs $29.99 and TATAT $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
GSDSP MagicFusion holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: TATAT has 22 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of GSDSP MagicFusion's written reviews are positive against 90% of TATAT's.
GSDSP MagicFusion ships an update every 6 weeks, TATAT every 19 months. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
