SunrizerXS synth

By BeepStreet

Open iTunes to buy and download apps.


Sunrizer XS 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 XS was built to perform and works perfectly with any MIDI keyboard or sequencer. A lot of research has been done in order to achieve unheard warmth and clarity.

*** The app requires at least iPhone 3GS or iPod Touch 3rd gen. iPhone4 or iPod Touch 4rd gen. recommended for full polyphony ***

· 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. It's possible to use 2 supersaw oscillators per voice · Polyphony: 7 voices on iPhone 4, 3 voices on iPhone 3GS
· Two independent filters per voice with configurable routing. You can select between various filter types including classic resonant LP,HP,BP,Notch and less common like Comb and Formant.
· 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, Akai SynthStation 25, MIDI mapping with learn function, Virtual Midi Ports and background audio

· 2 warm-sounding analog modelled oscillators per voice + 2 sub-oscillators (except SuperSaw). Available waveforms: Saw, PWM pulse,Triangle, SuperSaw.
· Oscillator 2 hard-sync and configurable routing
· Osc-mix, ring modulator
· FM (true frequency modulation), PM mode for second oscillator
· White noise oscillator

· Two independent filters per voice with configurable routing. You can select between various filter types including: resonant LP,HP,BP,Notch, Comb and Formant.
· Configurable routing: serial or parallel with bypass option.
· ADSR envelope, keyboard tracking and full LFO control

· 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

· A number of effects are built in: distortion, chorus, equalizer, stereo delay. All parameters can be modulated using mod-wheel.

· Sunrizer XS incorporates very powerful programmable arpeggiator. You should think of it more like a small step sequencer.

· Over 200 presets, ability to share cutom banks via email
· 7 voices polyphony
· Playback modes: poly, solo, arp
· Built-in recorder supporting AudioCopy and iTunes file sharing.
· Supports CoreMidi. MIDI key velocity can affect up to 3 parameters.
· Configurable piano keyboard size

"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."
Mark Jenkins, author "Analog Synthesizers"

"This virtual synthesizer is the highest quality digital instrument I have yet to discover for the iPad"

"Close your eyes for a minute and just listen. This thing sounds EXPENSIVE. "

"I predict that the one app that leads the charge of the high-end synth apps will start with an S."

Very impressive

I play lots of iOS synths and while most are useless, this one's a keeper. Only thing I'm puzzled and still questioning is, how do I play recordings, or is it possible to run recorded tracks in order to layer more tracks over those? An instruction/help section should be added. I've figured how to use the synth for the most part, it's very well laid out, but a user manual would be much appreciated. Thanks again for an awesome synth. Def one of the best if not the best for $3. You really can't ask for more at this price, I'm guessing, a user manual would take some time to write for this synth as it is a very detailed va synth. But hey if you guys put a manual together and make it an iap, I'd buy it. I feel like this synth has a lot of potential and use. Love how you included the natural circular knob twist feature as an option. Most iOS synths I played do not have this option, they all give the default linear knob turns, which is okay, but def not natural feeling when attempting a rotary motion.

Perfect. Great bang for your buck.

SunrizerXS is pretty much everything I was looking for in a mobile synth. Easy interface, great sound (for iPhone at least) and most of all, an arpeggiator sequencer. The main reason I bought this honestly was because of the step sequencer, since I’m no good tiptoeing around a keyboard I love to build sequences. Obviously the sequencer is limited to just building simple patterns but due to audiobus support you can easily track them out into Beatmaker 2, or just sample them on something else (like my MPC500)

The interface functions just like any subtractive synthesizer. If you’ve used one before it’s not hard to figure out. If you haven’t then this is a pretty good place to start honestly. You really can’t go wrong with this app. At this price you have very little to lose and a lot to gain

Works great with SynthStation 25

I bought this app mainly to use as a second performance synth with my Akai SynthStation 25 controller, and it works perfectly. The presets are amazing, the ability to customize tones is great too and very straightforward. My only request would be to be able to make a bank of favorites since there are so many presets and I forget which ones I like best.

For three bucks, this has almost all of the features of the much more expensive NLog synth, which was my default until this one.
