Midi Mock is a virtual musical keyboard that generates Midi note events through your Mac keyboard or mouse. This app sends Midi note events to software synthesizers and hardware synthesizer modules connected to your Mac, providing visual feedback of the notes being pressed on the keyboard.
Midi Mock can be also used as a polyphonic synthesizer on its own, to play the built-in Mac DLS sounds either through the Mac keyboard or by connecting a USB Midi keyboard to it.
It has mouse-operated pitch-bend and modulation wheels, octave transpose buttons and a velocity slider.
The "Global Keys" switch activates a feature to capture keypresses also when Midi Mock is not the frontmost window, making it perfect for playing softsynths through your Mac keyboard (e.g. Logic software instruments like the EXS24).
On the US keyboard layout, the keys generating Midi note events are the ones corresponding to the following letters and symbols:
top rows: Q2W3E4RT6Y7UI9O0P-[
bottom rows: ZSXDCVGBHNJM,
The physical position of the keys will be the same on any keyboard layout, but they may correspond to different letters and symbols depending on the specific country layout.
The arrow keys are mapped to the functions of internal sound program increase and decrease (right, left) and octave transpose (up, down), with autorepeat.
Added six keys to facilitate playing through the Mac keyboard; on the US keyboard layout the new keys correspond to the following letters and symbols: ] Backspace L . ; /
