Controlling Your Universe
Published in Keith Robinson, Ableton Live 9, 2014
When activated, the Key switch will turn orange, as will all of the map-able parameters and controls across Live’s user interface. Key mappings function just like MIDI mappings. To make assignments, enter Key Map Mode then click on a clip, control, or parameter. After you select one, type the key on the computer keyboard that you wish to make the assignment to. In order for key mapping to work, you must make sure that you have deactivated the Computer MIDI Keyboard. This is the keyboard-like button located next to the Key button. When this is activated (yellow), your computer keyboard will function as a MIDI note input device rather than a remote control. In this situation you would not be able to execute your key map assignments. While activated, any keys that share both mappings and MIDI input functions will cause the Computer MIDI Keyboard button and Key to light up orange when the conflicting keys are pressed.
Boolean Algebra and Circuit Realizations

There are two categories of switches, toggle and push-button. Toggle switches, such as light switches on a wall, remain in one state until “toggled” to the other state. This type switch will be discussed with respect to flip-flops and memory devices. The push-button switch is a momentary switch such as those found on a calculator or computer keyboard. These switches have a normal position and an asserted position and their behavior can be simulated by transistors in a logic switching circuit.
Combining evolutionary computation with the variable neighbourhood search in creating an artificial music composer
Published in Connection Science, 2019
As two useful features, the SYMPHONY (i) provides an opportunity for the user to see the notes while they are played, and (ii) enables the users to input a piece through playing it on a computer keyboard. Figures 8 and 9 show how the computer keyboard can be used by the user for playing notes and how saving capability can combine the played notes with the generated ones. Figure 9 also depicts how the SYMPHONY allows the user to select the parameters through a simple text file before the programme is being executed. Controllable parameters not seen in Figure 9 have been represented in Figure 10.
