"This really is the synth that keeps on giving! Inspiration and intuition truly blend together in this musical instrument." Alan Parsons Sunrizer Synth is a virtual analog synthesizer that takes the definition of iOS synthesizer to the next level. Thanks to carefully designed architecture and heavy usage of coprocessor it blurs the boundaries between iOS and hardware synthesizers. Sunrizer was built to perform and works perfectly with any MIDI keyboard or sequencer. A lot of research has been done in order to achieve unique character, warmth and clarity. HIGHLIGHTS · True SuperSaw sound emulation, first found in the legendary Roland JP-8000 synthesizer. SuperSaw is a layered waveform consisting of multiple saw waves which are detuned to create an extremely full and epic sound. · Two filters per voice with configurable routing. 16 filter types available, including less common like Comb, Formant or Frequency shifter. · The Morph Group function lets you continuously morph of up to 30 parameters in a sound (including effects), using only the modulation wheel. · Full support for CoreMidi, MIDI mapping, Virtual Midi Ports and background audio. · Multi mode lets you multiply oscillators to get unbelievably fat and full sound. · Support for microtuning - load scl and tun files. Create fascinating microtonal music which uses intervals not found in the Western system of 12 equal intervals to the octave. OSCILLATORS · 2 warm-sounding analog modelled oscillators, 2 sub-oscillators (except SuperSaw). Available waveforms: Saw, PWM pulse,Triangle, SuperSaw, FM (frequency of phase modulation). 6 oscillators per voice in multi-sono mode. · Oscillator 2 hard-sync and configurable routing · FM (true frequency modulation) and PM mode · Osc-mix, ring modulator · White noise oscillator FLEXIBLE MULTI FILTERS · Two independent filters per voice with configurable routing. Filter types: LPF, HPF, BPF, Analog LPF, Notch, Comb, All pass, Power LPF, Power BPF, Wave shaper, Resonator, Resampler, LPF+Resampler, Frequency shifter. · Configurable routing: serial or parallel with bypass option. · ADSR envelope, keyboard tracking and full LFO control. MODULATION · Two LFOs per voice. It's possible to assign each LFO to almost any parameter. 3 LFO running modes: trigger, 1 shot, global. 6 waveforms, phase and fade-in knobs. · The Morph Group function lets you continuously morph of up to 30 parameters in a sound (including effects), using only the modulation wheel. · Two Modulation ADSR Envelopes for amplitude and filters cutoff. · Pitch and modulation wheels. EFFECTS · A number of effects are built in: distortion, hi-q reverb, chorus, rotary speaker simulation, equalizer, phaser and stereo delay. Dual-band FX processing. ARPEGGIATOR · Sunrizer incorporates very powerful programmable arpeggiator. You should think of it more like a small step sequencer. OTHER FEATURES · Over 380 presets, 7 additional banks available for FREE in web library (more coming soon) · Hold button allows you to to keep notes sustaining until you play new notes · With Chord Memory function you can play the chord by only pressing single keys · Phrase sequencer · Compatible with AudioBus · Adjustable polyphony: 6-20 voices · Playback modes: poly, solo, arp · Built-in recorder supporting AudioCopy, DropBox and iTunes file sharing. · Supports AUv3, MIDI, IAA, AudioBus 2.0 Visit www.beepstreet.com for user manual and audio demos. * Sunrizer is now available on Mac and PC, check our website for more info "Specs aside, the most important thing is the sound… and it’s great." musicradar.com "Sunrizer is the first truly mature polyphonic synth for the iPad, a real, smooth and powerful sounding option for all sorts of stage and studio performances."

SynthMaster One iOS is KV331 Audio's first full blown universal synth app on iOS platform. It's a powerful wavetable synth with an intuitive workflow. With its simple layout, rich wavetable/waveform content and inspiring factory presets library, designing new sounds with SynthMaster One iOS is a joy. SynthMaster One iOS is feature wise identical to the desktop version except the following: * 16 voice polyphony (32 for the desktop version) * Comes with 650 presets (1250 for the desktop version) FEATURES * Universal App: SynthMaster One is now a universal standalone/AUv3 synth app running on iPhone 7 and above. * 650 Factory Presets: SynthMaster One iOS comes with inspiring factory presets from a world class team of sound designers: Arksun, Aiyn Zahev, BigTone Studios, Brian Transeau, Bluffmunkey, Bulent Biyikoglu, Gercek Dorman, Dejavu Sound, Fragment Audio, Kurt Ader, Mirko Ruta, Nori Ubukata, Rob Lee, Ufuk Kevser, Selcuk Ergen, The Machine, Vandalism Sound, Venus Theory, Vorpalsound and Xenos Soundworks * AUv3: SynthMaster One iOS supports AudioUnits V3, allowing multiple instances to run under supporting DAW apps like GarageBand, Cubasis or Beat Maker. * Files App Integration: Easily import/export presets, waveforms or scales using the common file browser UI (requires iOS 11+). * Real-time Modulation Feedback: See in real-time how modulation sources and targets change. This is a very helpful feature when designing sounds! * Cross Platform Cloud Synchronization: Easily synchronize your SynthMaster One related data across multiple platforms (Windows, MacOS, iPad, iPhone) * Semi-Modular Architecture: For each SynthMaster One instance, there are 2 oscillators with 2 sub oscillators, 2 Filters, 4 ADSR Envelopes, 3 LFOs, a powerful 16 step arpeggiator/sequencer and also 11 different effects that can be inserted on to 6 FX insert slots. The sub oscillators can be connected to the oscillators in 5 different modes which let you use it as a regular sub oscillator or do complex modulations such as ring modulation, amplitude modulation, phase modulation or frequency modulation. * 32 Step Arpeggiator/Sequencer: The arpeggiator in SynthMaster One features classic arpeggiator modes such as Up, Down, UpDown, DownUp, UpDown2, DownUp2, AsPlayed as well as Sequence, Chord and Arpeggiate modes. * Wavetable Synthesis: SynthMaster One implements true wavetable synthesis which opens up new possibilities for sound design. It comes with a rich content library with hundreds of waveforms and wavetables. * Stereo Oscillators with up to 16 voices Unison: Each of the 2 oscillators in SynthMaster One have stereo output, and can have up to 16 voices "unison". Using the "voices", "voices mix", "detune curve", "detune spread", "pan stread", "tone spread" and "phase spread" parameters, each oscillator can generate a rich "supersaw" type sound. * Zero Delay Feedback Filters: All of the 4 filter categories in SynthMaster One are developed using the zero delay feedback filter technology. With advanced filter parameters like input gain, drive, acid, filter nonlinearities and up to 4 times oversampling you can get that "analog" sound from the filters! * Rich Set of Effects: SynthMaster One features 11 different effect types: Distortion, LoFi, Ensemble, Phaser, 6 Band EQ, Compressor, Vocoder, Delay, Chorus, Tremolo, Reverb. * Microtuning: SynthMaster One supports Scala tuning, so tuning can be set either for each preset or globally by loading from a Scala tuning file. SynthMaster One comes with 300+ scales ranging from 5 note equal tempered scales to 12 note alternate tuning scales. * Preset Browser: SynthMaster One features a comprehensive preset browser with separate search criterias for instrument type, preset attributes, music style or preset author. SUPPORTS * All 64-bit iPad devices * AUv3 Audio Unit Extensions * Note-per-channel MIDI controllers (MPE) * Ableton Link * Bluetooth LE MIDI Controllers * AirDrop
