absolutely amazing! I've been using it for about 2 weeks and it's really really fun to make music with. you have to get kinda creative with your workflow, but the software is very powerful. the only thing I would like to see is a better pitch shifter, like one with an lfo, or even better, the ability to pitch shift in the sequencing tab. also it would be cool if you made a setting that allows you to play a sample all the way through and program pitch shifts through the sequencer.

Just stumbled on this app a couple weeks ago. Gotta say, it's the best sampler for android you'll ever find! I paid for the full version and paid for all the added features and if they release more features.....I'll be paying for those too! It's so intuitive I didn't even need a manual. It's so close to replacing my my entire DAW. Endless possibilities. Easy workflow. I can't get over how incredible it is. I've been creating source sounds on my PC and importing them to the app. 10X stars!!!!

Great sampler. Could have saved myself a lot of money on hardware if I had realized how intuitive and easy beatmaking could be on my phone. Once you figure out your little work flow this is a brilliant piece of kit for getting ideas down if they're centered around samples. You can screen record anything you see or hear on the internet, extract the audio, and import it into Koala sampler. In less than 1 minute you can start slicing & dicing. Pay the extra for the full version! Worth every penny!
