When World War I started, the proponents of women's suffrage ceased their activities and supported the war effort. In February 1918 women over the age of 30 received the right to vote. Suffrage rights for men and women were equalized in 1928. European countries such as Finland (1906), Norway (1913), and Denmark and Iceland (1915) granted women the vote early in the 20th century. Other continental powers were quick to accord women the right to vote at the end of World War I.
The MIDI sequencer allows the user to record and edit a musical performance without using an audio-based input source. The performance is recorded as a series of events that would ordinarily be played in from a keyboard instrument.
These messages are sent via a MIDI cable to other devices where they control sound generation and other features. A simple example of a MIDI setup is the use of a MIDI controller such as an electronic musical keyboard to trigger sounds created by a sound module. This MIDI data can also be recorded into a hardware or software device called a sequencer, which can be used to edit the data and to play it back at a later time.
