It’s great! It’s got two in-app purchases. The mixer is invaluable! I didn’t find much use for the extra time stretching options that came with the other plugin, but that’s probably due to the way I compose. I make loops out of one-shot samples. If you’re sampling entire loops, those are probably quite useful as well. Each plugin is only $5 or so. So $15 for everything Koala Sampler has to offer. Totally worth it!
