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.

· 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.

"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."

port the full version to iphone please

Crashes all the time on 6s, which is so sad because Sunrizer is one of the most warm and analog sounding synths apps out there. Add to that the in depth arpeggiator and good price tag and you have a pretty much flawless app 5/5 if not for all the bugs. Wish they'd update it to the ipad version SUNRIZER (full) for newer iphones since they could easily port it and the newer phones would run it flawlessly. Loses a star for crashing on ios 9 and also lacking the ipad version features when they'd be simple to port.

Come on. We support you please support us

GREAT!! ... but what's up with background audio & midi?

this was the first "real" synth app I purchased on on my iPad (4th gen retina) that I still use today. I held out on this version for the iPhone simply for the point of redundancy and storage (16G iPhone5s)
but with animoog for iPhone & Modular, my phone's core midi was getting a bit lonely ... plus I'm not one to use presets and I've spent lots of time making my own on the iPad - might as well use them across all devices, right?

well ... wrong. kind of.
Background Audio does not work on my iPhone5s nor does it send or receive midi on ANY channel.
I'm not sure I want to reset my phone for just this reason, but I'm at a loss. I've tried everything I can think of (including the recent update for animoog which sounded like the culprit, but nope).
gotta get this figured out and 5 stars it is.


I had a Korg MS2000 back in the day... This sounds better. It is simply astounding to hear how far iOS music apps have come. This doesn't sound like some half-way decent, toy pocket synth. It sounds like a full, powerful, "take me seriously" synth that can rival a lot of the hardware synths out there costing 100's and even 1000's more. I'm using sunrizerxs on my iPhone connected to a MIDI keyboard on stage for live shows! I'm blown away.....
