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.
Some synthesizer, sampler, and sequencer modules don't include a keyboard, and are triggered via MIDI. Soft synths, samplers, and sequencers are digital versions for the computer. A MIDI keyboard connected to the computer is normally used to trigger the computer's soft synths, samplers, and sequencer. Computer soft synth and sampler programs are often as feature-rich (minus keyboard), but are significantly cheaper.
