I love samplers. I especially love sampling my own voice and putting little 80s’esque panned repeating vowels throughout my own tracks. iOS has a good selection of samplers already such as sirSampleton and SampleWiz. I Am Sampler is new and is also quite good! It has 4 sample banks, LFO, bit crusher, delay and a reverse mode. We live in G-g-g-olden times. $1 USD in the App Store (link).
