"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."
