Great. Game!!!! ,

The Best I’ve seen on IOS so far!

First of all I’d like to say I hope you [The Developer] never sell out like some of these other music apps have. I can tell a lot of thought was put into making this App and I sincerely hope you continue to be successful and genuine on you’re journey!

As far as the app itself I’d say it’s quite literally what I’ve been looking for all day. I’ve bounced back from app to app, even GarageBand and I gotta say this app is well worth it and I highly favor it now over the last couple things i’ve downloaded.

The premium price is well worth what your getting and it even comes in parts. So your not paying for more than what you need. I’m happy to find there is no subscription. And there isn’t a million add-ons I need to buy every time I want ONE more single feature. It’s fair and well worth what your paying.

I’m able to take files straight out of my iPhone, throw it into the app on some Pads, chop it up and create patterns straight off my phone with ease! Among a plethora of other things I haven’t even discovered yet.

I really just wanted something I could use while on the go when I’m out’n about feeling inspired. All I got left to say is this app among an overly saturated App Store full of glitchy, uninspired, greedy Music Production apps is amazing and well worth the cost.

Trust if you continue down this path of being altruistic and offering quality along side reliability I will continue to support you!

My New SP-404 (and more)

This app is incredible. It’s maybe my single favorite app ever (not just music). If you are proficient with an SP-404 you will love this app.

It makes sample chopping such a pleasure. Beautiful, smooth, stable, precise - everything you could ever ask. So artfully laid out. The whole thing really is a work of art because of its beautiful simplicity and power. It embraces why people love the 404 despite its limitations and also embraces the iPad as an instrument. Thanks so much to the developer for this.

The one thing it kills compared to the 404 is the sequences. Bravo on that. It’s such a fast workflow. I can’t even explain how efficient it is. You just have to get in there and use it.

The effects are great on here but totally different than the 404. Good call on that too. You cannot do the 404 fx on an iPad. It wouldn’t work. This was a much smarter direction. (But if you nailed that vinyl sim, oh boy😳). The effects are really more like the pocket operator’s fx but more robust.

The one thing I would ask (to speed up my personal workflow significantly) would be to have an “export current sample” option just like you can export the current loop only. I do so much sample chopping in here and sometimes have a whole mess of things all in one file and would love to be able to just export one sample at a time.

Again, thanks for making my favorite app.

i love this app. 10 stars.

OLD VERSION: but lately after this new update even with NOTHING else playing on my ipad, everything is closed, background app refresh off, etc. It keeps randomly crashing on me and i lose all this work i had done. It is very very frustrating. not even beatmaker 3 or nanostudio do that. and Koala has never done it before. so If the amazing devs could figure this out for me then ill IMMEDIATLY GIVE 5 STARS. i only did one to get your attention. i use this app daily and i rely on it for a side income involving music production! please help!!

UPDATE: thank you so much for the extremely fast customer support. you sir are amazing!! i havent even had time to test the new update, but because the amazing dev got in touch with me so fast and worked so hard to try to fix it, i know that if i have any issues i can just email him directly and he will help me!! thank you so much

Developer Response ,

Hi pr4y, I’m really sorry this is happening to you. Since first reading your review, I have done everything within my means to make koala as stable as possible, and I have made an update for you specifically, I really really don’t want you to be frustrated or have a bad experience with koala. Again, I’m extremely sorry. Please update and let me know if it fixes your problems. (I can be contacted at https://www.elf-audio.com/contact.php)

UPDATE: I have now made a lot of stability enhancements to koala, if you get a chance can you let me know if it's working for you? All the best, and sorry again.
