The Samchillian Tip Tip Tip Cheeepeeeee is a keyboard MIDI controller of my own invention based on changes of pitch, rather than fixed pitches. This concept gives the performer the ability to perform extremely quick, rhapsodical lines.
 
Here's how it works: a user first selects a scale and a key (e.g. F# pentatonic), and then every key that is subsequently pressed will move the user up and down a certain amount within the selected set of notes, depending on the number of positive or negative number of steps assigned to that key. Also the user is able to select from a number of scales - including microtonal scales - and key signatures. A pattern, or "melodic contour", once learned, can then be played in any key or scale without needing to relearn fingering.
 
In the current incarnation I use a modified PC computer keyboard made by Kinesis®, which plugs into a laptop running the software that generates MIDI information. This information is then sent to a sampler or synthesizer which creates the sound.
 
Remember that since it is a MIDI controller, there is no distinctive sonic character to the instrument. However, the instrument tends to produce unusual phrases and patterns. Everything played on the Samchillian is completely live.
 
I had the help of these people in the making of Samchillian: Dan Coates and Ray Haleblian for software and Joe Waltz for hardware. And thank you to Adrian Romero for his support. (Also Lee Thalblum, and Richard Smith of MVS.)
