Mid vs TGX
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Mid
This app offers unique stereo transformations, allowing for smooth, continuous intervals between L/R and M/S representations. It enables new modulation possibilities and can be used as a width-preserving panner or to transform any stereo effect into an M/S one.
- Continuous mid-side interval
- Width-preserving panning
- Spatial modulation effect
- Transform stereo effects to M/S
- Lossless stereo field preservation
- Tempo sync capable LFO
- Paired mode for effect modulation

Ever wonder what lies between the L/R and M/S representations? Mid-Side Continuum extends the definition of mid-side encoding to create a smooth, continuous interval allowing in-between values and gradual changes. Channel mode switches can now be turned into faders, opening up new modulation possibilities as well. The algorithm used by the plugin is a true extension of the mid-side encoder/decoder concept and doesn't involve any cross-fading or other artificial constructs. The plugin can be used in two ways: • In standalone mode, as a width-preserving panning effect, or a special modulation effect for spatially balanced sounds • In paired mode, allowing other effects to operate anywhere between L/R and M/S modes, with modulation options available FEATURES: • Provides a new kind of spatial modulation effect for stereo signals • Can be used as a panner that doesn't squash wide components (existing ambience, reverb, stereo FX), strongly panning narrow parts at the same time • A great companion for delays or delay-based effects: explore adding space or change the panoramic character without re-configuring delay taps • Turn any stereo effect or effects chain into a M/S one (or any graduation on the L/R - M/S curve), by sandwiching them between a pair of Mid-Side Continuum instances • Unlike panning, stereo panning, or binaural panning, Mid-Side Continuum preserves the exact geometry of the stereo field by using a lossless transform • Higher rates of change can be used to create additional kinds of effects (chorus, warble/flutter), depending on the width characteristics of the original input • A tempo sync capable LFO is available to add automatic modulation; the LFO phase can be offset to allow precise timing control and alignment THE PANNER FOR REVERB-RICH SOUNDS: Panning high-ambience and reverb-rich sounds need no longer result in squashed stereo images. The exact, full width of the stereo field is preserved when using Mid-Side Continuum as a panning tool. Unlike binaural panning, the overall stereo frequency response is kept maximally flat, thanks to the used algorithm's audio engineering-focused feature set. In fact, Mid-Side Continuum's algorithm is a lossless, completely reversible one (based on True Pan's technology). WRAP ANY EFFECT TO CHANGE / MODULATE THEIR STEREO MODE: Two Mid-Side Continuum instances can be conveniently linked in a way that the second one cancels out the transformation, restoring the original sound. Once linked, the second plugin will automatically re-align if parameters are changed in the first one, without missing a single sample. Between these two points, any number of audio effects can be inserted, all of which will receive the transformed signal instead of the original L/R one. This setup can be used in multiple ways: either to just turn any stereo plugin into a M/S one, or to modulate the stereo field of the wet signals (while keeping the dry signal intact) without the need for setting up additional routing, thus keeping tracks neatly self-contained. VERSATILE EXTENSION TO DELAY-BASED EFFECTS: • Alter stereo delay patterns or turn a mono multi-tap delay into a stereo one on the fly • Instead of having to choose from the two, explore any setting between L/R and M/S delay modes to select the best-fitting stereo response • Remove excessive L/R slappiness without losing any stereo width by spatially equalizing the delay output, filling in directions not populated by L/R taps • Improve the clarity of the mid channel / mono mix when combining panned delays with shorter notes or more rhythmic passages • Lessen any "clockwork-like" quality of panned delays that may be experienced with some instruments or passages • Change or fine-tune delay patterns that emerge in the mono mix when using stereo delays PLEASE NOTE: • An Audio Unit v3 compatible host app is required to use this plugin

Released in 1991 this one is probably our second favorite synthesizer next to the EX5. The thing that made this synth amazing was it's AFM (Advanced FM Technology). Not only could it read the DX7 patches, but the enhanced AFM allowed for even better FM EPs with a ton of expression. The other thing you will recognize from this synth is it's incredible A/D converters which really make the synthesizer sound warm and phat. You can still hear the digital edge, but it's mixed with a warm analog tone that made all of the patches just sound professional and organic. Highlights: • Standalone and AUv3 Compatible • Yamaha SY99/77 Virtual Sample Library • 18GB Library (11GB Lossless on Disk) • Includes all 256 Factory Presets • Includes all RAW Waveforms • Includes all Drum Kits --------- The Ultimate Recreation of a Legendary Synth Classic: • Factory Presets - You get 128 Factory SY99 Presets and 128 Factory SY77 Factory Presets • Raw Waveforms - We give you access to the RAW Waveforms so that you can re-create some of your favorite patches. Our synthesis is powerful enough to get very close! • Capturing Nostalgia - Most of our presets use the exact wave layers as the hardware, which allows you to tweak to your liking. When needed, we used the sampled version. • Taking it to Another Level - Because our synthesizer is a bit more powerful than the hardware, you can now create presets that rival the hardware. • We sampled the factory presets with the effects on to capture the "exact" nostalgia of the hardware. --------- Standalone vs Pure Synth® Expansion - Standalone version has the black skeuomorphic interface - Expansion Unlocks inside of Pure Synth® FREE Player (https://apps.apple.com/us/app/pure-synth-platinum/id1459688500#see-all/in-app-purchases) - The Expansion includes the iPhone Version and the standalone does not - The Expansion includes the dynamic modulation from Pure Synth® - The Expansion allows you to mix and match libraries with one single interface ------- Sample Size and Space ▪ 18GB RAW Sound Library Before Lossless Compression ▪ 11GB Actual Size on Device After Lossless Compression ▪ 2GB RAM or Higher Required ***Lossless compression is a way to compress audio files without losing quality. ---------------- Device Specifications: ▪ 2GHz ARM Processor Recommended - iPad Pro 12.9 and 9.7 in, iPad 5th Gen, iPad Pro 12.9 in. (Gen 2), iPad Pro 10.5 in., iPad 6th Gen, iPad Pro 11 in., iPad Pro 12.9 in. (Gen 3), iPad Air (Gen 3) ▪ For External Sample Streaming, we only recommend Fast External SSD Drives (Not USB Thumb Drives) ---------------- External Drive Storage Our app is one of the first apps ever to offer external Drive Storage. In order to save space, you can store all of the samples on an external SSD and it will stream and read the sounds in real-time.
