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.
MIDI is a protocol that was developed so that electronic instruments could communicate with each other as well as computers and other electronic devices. Through MIDI, a variety of musical information can be transmitted. MIDI is not only used to indicate what note is played, but the duration of the note, the velocity/volume, and sometimes the aftertouch or other information as well. MIDI is also used to transmit non-note information such as pan, effects, track or overall volume, and the like. In essence, MIDI is a basic communications protocol used by musical instruments and computers, much like Firewire is a protocol for computers and peripheral devices like hard drives, scanners, and camcorders.
