With SpaceCraft (MIDI, MPE, AUv3, IAA) you can transform any sound into a playable musical instrument via Granular Synthesis. You can create textures, soundscapes and arpeggiated rhythms from sounds such as your voice, ambient noise or the high quality built-in audio samples. Tap the 'Input' button (top left) to record audio via your device's microphone or load a file from your device (access* to iCloud, Dropbox, Google Drive, Audioshare*** etc.). Experiment with turning everyday sounds into unusual instruments. Save your creations and corresponding samples via presets. Also, tap the 'rec' button (top right) to record your performance (maximum 20 minutes). This is used in standalone only as the AUv3 host can be used to record the output. Supports AUv3 and IAA (recommended to use in the effects slot to allow live input audio recording). * NOT COMPATIBLE with GarageBand as AUv3 (but can be loaded as Inter App Audio (IAA) or via an effects insert in the GarageBand sampler, with no MIDI capability) ** iOS11 and above provides equivalent folder access to the built-in iOS 'Files' app. Note that iOS10 and below has limited access to folders (no Audioshare folder access for iOS10 and below) *** Access to Audioshare files is done via the iOS files app
