Starrypad turns your iPhone into a drum pad, looper and sampler. Play sixteen velocity-sensitive pads with acoustic drums, 808 sounds and original synth phrases. The C Synth kit follows your tempo while keeping note pitch independent. Shape each pad with level, pan and tuning in the Mixer. Record from the microphone or import audio from a video you choose, trim the sound and assign it to a pad. Record loops, add layers and undo the latest pass. Switch from recording to playback without stopping the loop. Play along with music from another audio app. Background playback depends on the other app and your audio route. This does not import or record protected streaming audio. Export loops as WAV or MIDI. Connect an optional class-compliant USB MIDI controller. No controller, account or subscription is required. Settings and help support English, Japanese and Simplified Chinese. Familiar performance legends stay in English. Audio processing and your recordings stay on the device.
