MIDIKeys - Piano Keyboard CoreMIDI Control Surface|音樂線上App不用買-HotApp4Game

Note - iOS 8.3 caused the sliders in this app to become transparent. Will issue an update as soon as possible. I apologize for any inconvenience.MIDIKeys is a CoreMIDI keyboard control surface for the iPhone and iPod Touch.MIDIKeys doesn't produce any sound on its own, it is for playing hardware or software VST-style MIDI synthesizers via CoreMIDI hardware interfaces connected to the dock connector or virtual MIDI instruments such as IK Multimedia SampleTank or Sonosaurus ThumbJam running on your device.Please visit the app support website for the settings you will need to enable in the synth app you are using to have it work with the control surface. The entire range may be transposed up or down up to one octave in semitone increments using the "Transpose (semitones)" slider on the settings page or shifted a full octave (up to the two octave limit) by touching the 8va -/+ buttons on the main screen.Both fixed or variable note MIDI Note On event velocity based on touch position within the key are available as options on the settings page.While playing, you may also optionally send real-time volume, expression, modulation, or wind controller MIDI messages by tilting the iPhone/iPod Touch to the right or left.Touch anywhere on the background image at the top of the screen to cycle through the available skins. Settings are saved for the next time the app is run.
