Master keyboard
A master keyboard [ ˈmɑːstəˌkiːbɔːd ], also known as a MIDI keyboard, is a keyboard with an integrated MIDI controller for generating control data (MIDI commands) without generating its own sound.
The MIDI output of the master keyboard can be connected to a sound module or a computer , which then generates the desired sounds when you play the keys. A sequencer (e.g. computer with sequencer software) can also record key movements via MIDI and play them back later on any MIDI-capable device.
Simple master keyboards are available from around 35 euros and have up to three octaves with mini buttons. The higher-quality master keyboards have 88 weighted standard keys with hammer action to simulate the feel of a piano . In addition, they offer playing aids such as modulation wheels , aftertouch and other special functions in order to be able to control devices that are mostly connected via MIDI, for example to select instrument sounds on these devices. In addition to a MIDI connection, master keyboards have recently also offered a USB connection, or they have dispensed with a MIDI connection entirely.
Most digital pianos and personal keyboards mostly also have simple master keyboard functions.
