I continue to build my sound effects library with lots of different cartoon voices including hi-pitched "minion-like" sounds. I usually start with my Neumann U87 to record the vocalizations and then mix them out so I can sample them. Then I pitch the samples up using my keyboard and then drop them back into Logic Pro X to add EQ and compression. Some of my minion sounds have been incorporated into the well known Youtube Fuzzy Puppet Show cartoon.
