Voxkit! app for iPhone and iPad

Voxkit is a fundamentally different iOS music instrument, designed for drums, bass lines, and backing chords. While you can trigger sounds by touching the screen, the app is designed to trigger notes with sound.

Play with drum sticks on a practice pad -- Voxkit can hear the strike, and transforms this into a drum sample, a bass note, and more. You can beat box, tap a pencil on a desk, clap your hands.

Triggering notes with sound has a number of advantages. First, you can use drum sticks on any surface (other than your iOS device, of course); the bounce you get from the stick will help you keep in time. Theres also less latency and jitter in the notes; sound moves through iOS like clockwork, while touches on the iPad screen can sometimes be delayed.

Voxkit uses a high performance spectral analysis engine to detect the tone of the first fraction of a second of sound -- and from this, it can trigger up to four different notes. Play a snare on a practice pad, use your voice to trigger a bass drum, and strike the sticks together for a cymbal.

The interface is arranged with four rows, with four pads each. Each row supports a separate SoundFont instrument; built in to the app are hundreds of sampled sounds from pianos, guitars, bass, synthesizers, and thousands of percussion sounds.

Each pad can play a single note, a chord, or even send MIDI control change and program change messages.

The app supports Audiobus 2.1 with preset sharing, Inter-App Audio, MIDI input and output, and MIDI over Bluetooth. Presets for the pads can be shared and imported from Email, or through Twitter.

With four separate SoundFont engines, and incoming audio signal processing, we recommend the iPad4 and better for the best performance. For less powerful devices, individual SoundFont engines can be turned off if not needed, and the app can be used as a simple MIDI controller. With the built-in Apollo MIDI over Bluetooth, you can use the app as a wireless controller for another device running a synthesis or sampler engine.
