BLEASS Alpha Synthesizer is a versatile virtual analogue polyphonic synthesizer built for immediate, hands-on sound design. Its three oscillators combine variable waveshapes and pulse widths with unison, hard sync, cross modulation and ring modulation, while dual variable-state filters with drive add further colour and character. The streamlined interface follows the natural signal path, keeping powerful synthesis controls accessible at a glance. Bring sounds to life with three ADSR envelopes, two multi-waveform LFOs and extensive modulation possibilities, while the Motion Sequencer adds rhythmic and expressive movement that can work hand in hand with the built-in arpeggiator. MPE support extends the performance possibilities, and BLEASS' efficient audio engine keeps the experience smooth and responsive on mobile devices. A complete built-in effects section includes Overdrive, Bitcrusher, Tremolo, filtered ping-pong Delay and Reverb, adding everything from subtle movement to more radical processing directly within the synth. More than 200 factory presets provide ready-to-play sounds and starting points for your own creations. BLEASS Alpha Synthesizer can be used as a standalone app or AUv3 instrument on iPhone and iPad. Also available for Windows and macOS. More information and technical specifications available on: https://www.bleass.com/alpha/

• Inspired by famous phaser units from guitarist and keyboardist world • Unique sonic character combined with a large amount of control • Adjustable LFO; diverse waveforms and synchronizable to host tempo • Versatile: External modulation (parameters), Step mode, and more • Unique Butterfly Meter: Shows LFO modulation and output level • Suitable for all musical genres and instruments • Stereo, adjustable phase modulation distance between both channels • Includes various presets for inspiration • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Phazer will satisfy most fans of phasing effects, seducing them with its rich sonic palette and elegant interface. 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
