Oscillator vs Musk MIDI Keyboard

Oscillator is a simple and rough audio generator application which has the following functions. You can use it as a test tone and play it as a strange musical instrument. - Four waveforms. (i.e. sine wave, square wave, saw wave and white noise.) - Exponential Frequency control using the slider. - Frequency numeric input using the software keyboard. - Equal distance panning control using the slider. - dB style amplitude control using the slider. - Sound output on/off button. - All sliders and buttons are multi-touch controlled. Please note the limitations below before you purchase/use this application. - The frequency control is not effective with the white noise oscillator. - The panning control is not effective with an iPhone internal speaker because it is monophonic. Use headphones or stereo speakers. - The audio output might be interrupted on a keyboard input, a view change and so on. - The accuracy of the audio output is not very high but it is reasonable.
