Takete has been designed to operate at its best on iPad Air 1 or equivalent. It will work on any device from iPad 2 and up though. It is a very scalable piece of software. This means that an inferior piece of hardware can be utilised by adapting your usage to the devices ability. This will involve using lower resolution videos and relying more on video FX than video file players. For audio the best way to maximise performance is to use less channels simultaneously, avoid CPU intensive FX such as reverb and minimise usage of more intensive instruments like Granular.
