Koala is the ultimate pocket-sized sampler. Record anything with your phone's mic or load your own sounds. Use Koala to create beats with those samples, add effects and create a track!
Koala’s super intuitive interface helps you make a tracks in a flash, there is no brake pedal. You can also resample the output of the app back into the input, through the effects, so the sonic possibilities are endless.
Koala's design focuses totally on making the music making progress instant, keeping you in the flow and keeping it fun, not getting bogged down by pages of parameters and micro-editing.
"Been putting that $4 koala sampler to good use lately. Undeniably great tool that puts some of these expensive beat boxes to shame. A must cop." -- flying lotus, twitter

This will make you spend around 18 euro all together. no problem. Anyways I think that a.i. splitstems is weaker than anything. I just can't get much out of it. importing video is easy but navigating trough the phone to find something with it is just crazy hard. I cannot find anything in my phone, I rather screen record any audio and then import as video. 2 and half stars

so fun! I play and record songs on a variety of formats and never really played with samplers because I found them complicated at least for me. koala is so easy to pick up and just experiment and have fun with. I doubt I could really have something in my head and make it exactly the way I intended, but I dont really think that's the point here. at least for me, it's more about working fast and exploring, which koala excels at.

I love this app so much, and I would give it 5 stars if it weren't for this one weird bug that happens intermittently. Sometimes, when I open the app, the audio output just won't work at all regardless of the device I'm using. I've fully upgraded the app because it's just so feature-loaded and I adore the workflow of it, but this bug drives me crazy and completely kills my creative impulse when it happens!
