Fantastic sound. This is going to be my number one synth for audiobus

Really appreciate the update.

Otherworldly sounds. Fantastic interface. Crystal is unique and powerful!

Great, great app, especially if you also use the desktop version. The biggest improvement would be the ability to Load/Save banks so you could upload desktop banks and have multiple ones to choose from at once. Show more

This thing has lots of parameters. I tried the VST version of this, and it had lots of potential, but on the iPad it is easier to use. If you like designing evolving pads, this app rocks. Lots of sonic potential, comparable to PPG Wavegenerator. Audiobus support would rock. Show more

No good. The idea is great. It crashes on ipad2 with latest OS. It sounds are ok until you try to adjust parimeters, then all clicks and then crash. No good. Newest update does not solve the crash issue. Horrible app. This app is no fun. The sounds are not up to par with other synth apps like Animoog and TC-11. I do realize that it is cheaper in price, but the bar has been set. Adjusting parameters in this app is no fun. The interface is not too good. I would recommend avoiding this app and getting something better. Show more

Sup with the horrid icon. I would of thought by now we would of at least had one to compliment the Retina Display. Long overdue for a redesign.

This music synth is a bread-and-butter sound maker that I've been relying on for years: first on the desktop, then the iPhone, and now the iPad. This update adds a couple of bells and whistles to the mainstay features, which continue to be outstanding: lots of good preset sounds, plus the ability to be creative and make your own. Lots of functionality with a very user-friendly interface. This can be used stand-alone, but works best when coupled with a MIDI keyboard. Recommended both for beginners or advanced alike. Show more

I really like this app because it is so inspiring and makes very rich sounds. I could play it all day with the way the music swirls and moves. I can breed new presets so there are always new presets to play with. Well done! Show more

It's great that you can share patches with the desktop version, but the lack of polyphony on the iOS version is a serious deficiency. It's confounding that the desktop version supports polyphony on a 500 MHz PC, but the iOS app doesn't support polyphony even on an iPad 2 with multiple 1+ GHz cores. As of this writing, the app's description makes no mention of this frustrating limitation. Show more

The sonic possibilities are good, so if you want to tinker around with making patches, it's great. If you want to then use those patches for music, it goes downhill somewhat due to latency, and limited midi capability (limited cc mapping foretc.). Crystal synth has definite potential, though and is a bargain for the price, even for a single evening's tinkering. Show more

the sound just starts becoming distorted and buggy about as soon as I press a note on the iphone 4. Pretty interested in this app... it worked for a second and it could sound cool.. please fix! Show more

Not much to say over that other than the title . Very complex wavetable/subtractive synth for 5$

This virtual instrument is one of the best for the iPad, you create amazing soundscapes and the quality and control are topnotch. It only need virtual midi to work at the same time with other apps. Show more

I've had the AU for years and to this days use the presets, modified a bit to taste on almost every track (and i have almost all the big boy synths). Show more

Crashes on launch with iPad2 running iOs 5. An utter waste of money until (if) it gets fixed. Beware.

This is a great app please fix to work with OS5...!

Decent engine, however within 10 minutes of owning its crashed twice, not sure what to think about that. Play surface stopped responding once, next time it crashed when trying the record function... Show more

I like the sounds except there are a lot of crackles and pops going on. Something about the sound engine isn't optimized. There are other synths out there doing as much or more than Crystal XT and they don't seem to have the issue. Show more

I have several synths of all different types, and Crystal is extremely impressive. The tweaking abilities are enormous, not to mention the mind boggling possibilities that come with that. It really is a tweakers dream. It's all laid in a very intuitive interface. I found no need for documentation. Maybe if you're new to synthesizer basics a little instruction might help, but it's just laid out so well even the dimmest lit light bulb could deal with this. The presets are all pretty darn good as well, very unique and creative. It's easy to take one of those and make it your own with some creative tweaking with up to 3 different voices, multiple delay layers, envelope, and everything else you can possibly desire. Exporting to other apps is easy as it gets. Just record a performance, go to the other app and paste. Too easy! The price is a fantastic value. I just can't recommend this enough Show more
