Tri-O is an algorithmic MIDI controller that allows you to easily create life-like effects for your digital a/v project. Based on an open-ended Cartesian geometry system, TRI-O generates a set of complex signal flows. On its surface, three speed-adjustable discs drive the endless transformation of a triangle. The machine calculates the area, side lengths, and angle values of the changing triangle, converts them into separate MIDI signals so that they can be assigned respectively to different parameters of a (external) sound synthesizer. All the output signals of TRI-O are non-linear, unpredictable and "organically" interrelated. It can be connected to MIDI-compatible synthesizers, audio/visual workstation, etc., via a USB cable.

Some highlights

-works on USB-MIDI compatible device
-3 adjustable speed knobs(top surface) for each wheel to avoid pattern repetition of the signal
-1 selector knob and 2 max/min knobs (front) enables scaling output signals respectively
-light, firm, portable, walnut wood body

Motivations

The design idea behind “Tri-O” is simultaneously originated from the challenging to the “precise control” promoted by popular MIDI controllers and questioning the practicality of applying randomness to music compositions. It seeks a balance point between top-down control and absolute autonomy in electronic music practice.

For a user interacting with TRI-O, the attempt to "control everything precisely" is a little bit out-dated, since here it is the instrument that does the main job- it flows as if it's improvising, but it behaves in a humanized fashion comparing to a random number generator. Since we only have the access to alter its behavior (by changing the wheels' speed), we are not likely be able to turn it to the exact value we want. But instead, we work cooperatively WITH it-it's fun to play with. This redefines the role of a user- a plan maker, and a modifier instead of a dominator. TRI-O is an experiment on this new relationship.
