The Soundplane Model A is a computer music controller with the sensitivity and feel of an acoustic instrument. It detects a wide range of touches on its walnut playing surface, from a light tickle to a very firm press. Unlike a MIDI keyboard, which typically sends out just one velocity value at the start of a note, the Soundplane communicates three dimensions of information, x, y and pressure, over the entire duration of every touch. As a synthesist, this lets you replace a triggered envelope with an intimate connection and breathe life into each note.
