• Fantastic ★★★★★
    This thing is also a work of art. It is a sound maker's dream tool. It's very cool that the designer gives such credit to John Chowning and Max Matthews (look them up if you are not familiar.) Hours and hours of very original sounds come out of this. Ps. I'm not affiliated with apeSoft in any way. Even if they wanted to pay me to write these reviews i would turn down the offer. ( not vst versions!) Edit: made a comparison to iPulsaret but i was thinking iDensity not Stria. 2 years later i am still impressed.

  • Experimental Madness! ★★★★★
    Stria seems essential to me as someone who loves experimental music, avant-garde weirdness. Amazing way to play with process sound. Fans of apps like SoundScaper will love all of apesoft's apps in this series. It was also a bonus to look into where the word Stria came from in relation to electronic music. Have fun!

  • Fascinating app -but requires patience ★★★★★
    My initial impression was that this app was good for ethereal sound effects. After exploring it in depth by stripping down to the basics, I am now finding there are quite musical alternate tuning capabilities. The ability to modulate every parameter via the controller page opens up endless possibilities. Been able to conjure up sounds and alternate turnings reminiscent of W. Carlos's "Beauty and the Beast". Very cool.

  • Wondeful and Strange ★★★★★
    If you are into CCRMA/IRCAM, or just want crazy unique sounds then this is pretty decent. Not as essential as some of their other apps, but definitely inspiring.

  • apeSoft does it again ★★★★★
    This is my favorite synth of apeSoft's lauded catalog of iOS synths. There's a plethora of FM synths available but few that reach the capabilities of Stria. In fact, the quality of sound and range of timbres that Stria offers. I've been trying to get Stria to work with Line 6's Mobilekeys49 controller. To date that is the only negative I find with this delightful synth. As is true with every apeSoft synth there is a good store of sonic mayhem to be had. A couple things that make Stria different are the controls for major and minor synthesis features. If you've worked with iDensity or iPulseret you'll feel comfortable with this similar styled GUI. Even better, Stria has a much simpler approach to FM synthesis. Instead of the typical mimicking of analog interfaces apeSoft uses what they call an analog design, and it works like that, but it is a bit more from the digital age minus tons of menus that obfuscate programming. Programming is simple by FM terms and fairly simple for the amount of function available. I'm a sucker for additive synthesis which is an another great feature of Stria. It's a modest implementation but compared to most "additive" synths for the iOS it's nicely featured and easy to program. So, what about the sound? What's so great about Stria? First of all the quality is very clear without the frequency distortion that plagues many iOS FM synth implementations. The range of sounds are typical FM: great bells, percussion, and motion sounds. The additive sounds are a bit more basic but sound warmer than many additive synths tend to. Throughout its range Stria sounds warmer, fuller, and more organic than one might expect. In part this is due to the intensity of modulation and frequency relations. A very useful part of Stria's sound engine are the many assignments available in the Controller section of the synth. You can work with MIDI or between various editing systems that are part of Stria's sound design system. Think of the Controller menu as a soured up modulation matrix that goes way beyond modulation. Now, for the things I'd like to see: 1) a keyboard 2) a system that allows users to find where notes are, the basics are already in Stria's programming system 3) scale design with the most used as presets These three additions would be very useful and personally welcomed. As Stria works presently (iPad 3, 32gb) you use an X/Y screen for velocity/volume. Each axis works as programmed, usually with pitch on the Y axis as well as anything else you want to program. This is its best feature and why a keyboard should be included.
