Transfer your Beatmaker 3 kits to your iOS device and they load as presets. See Transferring to iOS Devices.

Beatmaker 3 accepted sample audio file formats: .wav

Kits are saved in the bmk2 format, which loads fine in Beatmaker 3. Empty pads show an EMPTY.wav file.

The Choke Hi-Hats option in Preferences works for Beatmaker 3 kits too, so a closed hat cuts off an open one.
