  1. pecos jim-avatar

    Very cool versatile app. Haven't tried pro version yet, but the free version is fun and useful. You can import audio and loops, resample and tweak the audio, lots of possibilities if you get creative with it. It's a great tool for a DAWless guitar looper stuff.

    Hours of creative production possibilities. Many effects and filters. Great tool for musique concrète.

  3. Scott L Wilson-avatar

    A great granular synthesizer! Love it!

  4. ken fusion-avatar

    This app is awesome . Downside of play store hounding for a review immediately after download . I was still finding my way around.(previous review, had a question) I look forward to going deep into this amazing tool for use in sound design . Thank you for your hard work , and timely response to my review .I did not expect this level of functionality on an app. I am blown away .i will re edit my review .

  5. Ess Ortijs-avatar

    This app is beautiful. The amount of flexibility and depth within it are fascinating. Ican take a simple loop and create and morphing, expansive texture with little effort. I've used it in a number of pieces and am more than pleased. I'd like some clear instructions online somewhere that I may refer to in order to access some of the deeper capabilities, but overall, I'm very happy.

  6. 077-avatar

    Why can't I clear or discard what i just did? Also, there's no such undo/redo feature in this app. It would be great if there'd been one cause then you can experiment and explore more. Hope the engineers focus a bit more on UI cause it's a great app and can be something really cool.

  7. Big Iggy-avatar

    Awesome sauce!! Especially for free! Super fun and easy to mess around with for new ideas!

    This is instant inspiration if you are into granular or glitchy stuff. I recorded myself knocking on a table w my phone's mic and turned it into sth i can vibe to by just messing around.

  9. Thomas Joseph-avatar

    This Is one of the best apps I've ever Installed! Definitely useful to experiment with any sound or track imaginable. With lots of effects, features, and options available, which I like. I hope this app stays In this store for what It's worth!

  10. Tyler Martin-avatar

    Such a cool app! Capable of very interesting textures. Remarkably powerful and full featured!

    This app can do a whole range of mangling, and the 4 tracks allow for some pretty deep and complex textures.

    This is amazing! Brilliant! Incredible! So much fun I'm sure they'll pass a law soon. Get it while you can. Lol

    Dramatic discovery. Endless possibilities of sonic creation. Woefully underdocumented BUT well worth the ten million bucks worth of power at your fingertip. It will make you want to write the lost manual on your way to Xanadu.

  14. Michael Toop-avatar

    Amazing app. Loads of audio features.

  15. Larry Cushman-avatar

    When people say an app is COOL or is GREAT, it is no comparison to this app. This is the BEST app I've ever seen or used. Thankyou Grainstorm for providing me with this CREATIVE outlet my soul requires.

  16. Martijn J-avatar

    Please provide information about the update here in the playstore. BEFORE you download it.

    Awesome for recording straight into Renoise and Reason!

  18. Brian-avatar

    Very easy to loop & grunge up a sample.

  19. Kris Dubenic-avatar

    This app is essential for any ambient/noise musician. I've been using the pro version for over 1 year and it has allowed me to make some serious tracks while travelling/not in the studio. It can turn anything into an endlessly evolving ethereal dream or your worst nightmare. I still haven't tapped into the vast power and possibility inherent in this program. The highest recommendation to those considering it and a hearfelt thanks to the developers for making such an amazing app.

  20. ঊ eggo.-avatar

    The interface is incredibly confusing and hardly anything makes sense. I couldn't play any sounds that I uploaded. Nothing was clear. EDIT: I appreciate the feedback and actually acting upon it, very uncommon to see. I'm trying the app again and I like it.

  21. Kris Amphlett-avatar

    Great work! I only used it for 10 minutes and I could already work out what the controls were. It would be really handy if there was a way to be able.e to view the waveform and scanning while adjusting parameters... unless the parameters have midi compatibility? Either way, very interesting and worth getting of your into granular synthesis and sound design, or just want to make weird and wonderful sounds!

  22. km c-avatar

    Makes cool sounds but its very hard to understand (what's actually happening) even as a music producer with experience of synthesis. Also, glitchy sometimes and hard to use controls precicily. Also no way to export or record in app?

  23. John Gregory-avatar

    This app is a ton of fun for creating experimental tonality. Don't expect anything that's going to be easily loopable but do you expect to have a great time making noise. I'm anxious to plug it in and do some recording! I would love to have a version of this that I can pay for it that's a little bit more expansive with features (easy MIDI looping, a sequencer, etc. .) but I'm excited to have a new toy to play with. If the developers would like any feedback I would love to make some suggestions...

  24. ed willow-avatar

    My fav app for experimenting with sound

    Just what I was looking for! Perfect for my spooky soundscapes. Instructions are clear, but it's not a beginner friendly tutorial (it can be a problem for some users). Just one question - could it be updated to record selected track outputs separatley or it would be too demanding for a phone? (Samsung note 10+) Need to test it with a midi device before purchase

  26. Nate Buker-avatar

    Completely unresponsive after installing and starting up. Stunning disappointment.

  27. ola wikström-avatar

    Some weird bugs has appeared since the last two updates.. 1) can't import m4a files or some mp3/wav files anymore. The app says "invalid data found when processing input".. 2) when importing mp3-files(the ones that I'm actually able to open) the app changes playback speed to what sounds like 0.5 speed. The sound is also heavily distorted. So far I haven't been able to use the app since these errors started occurring, hope they get fixed in some way. Cause I looooooove the app. And I miss it

    how can you export the processed audio file? Nice app

  29. Sach Motee-avatar

    don't often do this but this is a genuinely great synth for android. spend some time with it and it rewards. I had the free version and was so impressed I've bought the jenkin version. Would love to be able to use this live, on the fly with a mike/instrument

  30. Joe La Sac-avatar

    As a dabbler in music production, this app is sweet! Records up to 4 tracks. Find the "sweet spot" with speed, pitch, and low latency granular modulations that allow you to morph the audios into amazing experiments.

  31. Al Yeska-avatar

    I wish I were knowledgeable enough to like it more. There is no friendliness in this app for the naive. Nor is the browser easy to navigate, in it's root depth. I lost my place and can no longer find waves to load. Perhaps, one day, small sample packs could become available to download?

  32. Kylie M-avatar

    Cool app but how do you save anything you've made into a new file of its own? It's so confusing.

    This is a lot of fun. When I stream the sound to my amplifier, I can hear it in full quality, with a little delay. Awesome! I will by "pro" later, just to support the project.

  34. bobby greene-avatar

    i Love it theres nothing comes close to for catching electronic voice phenomena .im not joking but I have had entire conversations with many dead relatives and other trapped spirits and several demons it May not have been designed for it but that's what I have been using it for and it works great

    Profoundly astounding granular synthesis app, very easy to figure out for anyone with an open mind and an appreciation for lovely oddities like this. Having years of experience in sampling and sythesisers did help but having none would get some pretty good results also

  36. A Binder-avatar

    Really nice app with so many possibilities, and thats only in the free version. good for making brutal noises, ambient vaporwave tracks, cool loops, etc etc etc Pretty easy to learn and relatively intuitive if youre familiar with synths.

    Hey there. very nice tool. makes so much fun to experiment. is there any possibility to record without using an audio interface on my computer and connect my smartphone to it?

  39. Andreas Hamre-avatar

    this app activates your mic twice a day in the background even if you're not using the app. I see you claim this is not true in another review so I'll be happy to provide you screenshots of my permissions log.

  42. Althepsyphros-avatar

    Absolutely profoundly atrocious instructions. Worst instructions I have ever read in my entire synth using career. I still cant figure out what half of the knobs are actually doing.

  43. J McLain-avatar

    Great great app that you can make so many on the go soundscapes with.

    I LOVE IT! What sort of sick, twisted mind does this? ... Makes this?... Listens to this? It's so freakishly cool! If you've got a lifetime to waste tweaking virtual knobs and reshaping samples, you will absolutely love this, and never find all the of the possibilities. Gorgeously twisted sonic experimentation with loads of weird science for your darkest moments. If you tweak audio, try this.

  82. Jer Nej-avatar

    (Edit: excellent update, double tap to go back to default is perfect!) Amazing. Even free version. Perfect for quick fix while commuting or go deep while in studio/home. And it keeps being updated. GUI is very minimal which I love - it is a bit cluttered but with so many features that's a normal compromise. Anyhow, really really good stuff here.

  83. Liuong-avatar

    This app is amazing for quick sound design..I just bought unlocker today but it doesn't want to load presets..it saves them but on load it does nothing..Am i doing something wrong or your app have a bug ? Im using galaxy edge 7..Please help..

  96. A Google user-avatar

    This is an interesting noisemaker. It makes the wife quite grumpy; she has banished me to a closet. The instructions could be a little more clear. Perhaps a tutorial could be created? I haven't quite figured out how to save anything for use in a project, but maybe that's a paid feature? The effects were rather hard to find; I actually found them by accident. Overall, it's a cool app. The various controls can be a bit buggy and insensitive, and that would have to be worked out before I felt compelled to upgrade. If composing computer generated music is something that your into, this app is worth exploring. If you are an occasional hobbyist, you may find this app to be a little highly priced, and a little more in depth than you want or need, but it's still worth downloading the free version, just to check it out. Guaranteed to thoroughly annoy spouses, parents, teachers, siblings, or anyone else that's bothered by unnatural noise.
