The Samchillian Tip Tip Tip Cheeepeeeee
Leon Gruenbaum · 2007
Almost all traditional musical instruments have a one-to-one correspondence between a given fingering and the pitch that sounds for that fingering. The Samchillian Tip Tip Tip Cheeepeeeee does not - it is a keyboard MIDI controller that is based on intervals rather than fixed pitches. That is, a given keypress will sound a pitch a number of steps away from the last note sounded (within the key signature and scale selected) according to the 'delta' value assigned to that key. The advantages of such a system are convenience, speed, and the ability to play difficult, unusual and/or unintended passages extemporaneously.
