Expression types include: Velocity sensitivity —how fast the key is pressed. Aftertouch, or pressure ...
Also in 1983, Dave Smith's company marketed the first polyphonic synthesizer keyboard that could play more than one sound at a time called the 'Six-Trak'. It had a six track sequencer and each track could access a different sound. The same year the SCI Pooppit T8 with optical key sensing became the first piano action emulating MIDI keyboard.
