To achieve the classic phase effect, the original signal is blended with a slightly out-of-phase copy of itself. Altering the timing difference between the two signals produces the swooshing sound characteristic of phasing. Most phaser units available on the market are built around this circuit topology, each with its own specificities and limitations. Guitar pedals provide a great sonic signature out of the box and are a great source of inspiration, but we often overlook the impressive built-in effects sections of some hardware synthesizers. FAC Phazer combines the best of both worlds into a single plugin, offering access to all parameters involved in crafting the phasing effect. The design and development were inspired by both pedals and built-in phaser effects found in hardware synthesizers. This led to the creation of four unique characters: Classic, Midori, Step, and Tirus. All parameters can be applied to each of these characters, allowing you to create new, exciting, and outstanding sounds. The presets Slow, Moderate, and Jumpy Phase Pedal or also Fleur d’Oranger bring the classic pedals sound signature within your reach. If you're seeking more modern characteristics, the Step Sound I preset offers a splendid stepping mode, while the Midori Phase Shift II preset emphasizes the feedback in a unique way. On the other hand, the Tirus Anthem preset is an excellent starting point for exploring phasing effects produced with built-in synthesizer effects. An important aspect that strongly contributes to the variety of the sonic palette provided by the plugin is the modulation options. The LFO can run in free mode, be synchronized to the host tempo, or be defined by external automation parameters. The documentation is available at fredantoncorvest.com/FAC_Phazer.html

Please note: This App comes with an AUv3 plugin extension. Red Animal is a component modeling emulation of a vintage Vox Continenal 301 electronic organ. INSTRUMENT BACKGROUND Bands like the Doors, the Animals, the Monkees made the Vox Continental one of the most famous electronic organs of the 60's. This particular model was made in the UK and also in Italy and was rather simple in both electronics and features. Like many other electronic organs of the same age, the sound generator is based on the so-called "Top Octave Synthesizer", TOS for short, responsible of the generation of 12 waveforms, one for each note of the last octave of the organ keyboard. The basic waveform in this case is a low-pass filtered square wave. The lower octaves are produced by means of "divider" circuits that halve the frequency of each waveform, going so forth for each lower octave down to the pedalboard tones. This organs offers only two different registers: Sine and Master, with 4 different foot lengths. The sound engine of GSi Red Animal is also featured in the GSi Gemini and the Crumar Mojo 61. Of course this type of instrument gives its best if run through external effects and amps. Have a look at the GSi catalog and experiment with some of the effects offered by GSi. Main features: - Component Modeling engine (no samples, all real-time synthesis) - Full Polyphony (61 notes, 12 Top-Octave Oscillators + Frequency Dividers) - Key multi-contact simulation with authentic and adjustable key click - Authentic recreation of the Vox register filters - Recreation of the background noise and leakage - Adjustable vibrato (speed and depth) - Built-in Stereo Delay effect - Built-in Stereo Reverb effect - Built-in programmer with unlimited Programs - Embedded user's manual - Available as Stand-alone application and audio plugin - Very low CPU and RAM usage

Verdict
The clearest difference is in-app purchases: Red Animal at none against FAC Phazer's 3. Red Animal also leads on iOS requirement (9.3 vs 16.4). FAC Phazer's advantage is price ($9.99 vs $14.99) and rating (5.0 vs 4.8). On update cadence, ads, monetization model and device support there is nothing between them.
